X-Ray Laser For Creating Supercharged Particles

samzenpus posted more than 2 years ago | from the charge-it-up dept.

William Robinson writes "Scientists have found way to use X-Ray Lasers to create supercharged particles. The specific tuning of the laser's properties can cause atoms and molecules to resonate. The resonance excites the atoms and causes them to shake off electrons at a rate that otherwise would require higher energies. This could be used to create highly charged plasma."

An example for applciation: High charged particles are used for ion-beam radiotherapy in the fight against cancer. There are no known side-effects like at chemotherapy, but of course you cannot use the beam for every type of cancer. Unfortunately, the acutal beam of high chared particles needs an particle-accelerator which dimensons surpasses any garage. The new tech could probaly shrink the size of an ion generator, which would help to spreade the therapy with ions more to compensate the common x-ray radiotherapy with its bad collateral damage.

What I've seen of heavy ion beam therapy uses carbon ions, which should be something that could be fully ionized in something the size of shoe-box to a mini-fridge depending on if you want to count the power supply and vacuum equipment. The majority of the size is that ion based therapy uses much higher energies of couple hundred MeV per particle than other kinds of beam based therapy. This probably won't help much with that, especially considering in this case the x-ray laser source uses a GeV electron accelerator. Although if they get it to work with much weaker x-ray laser sources, it might help a little.

This is what Peter Hagelstein was developing before his research got co-opted by his thesis advisor to lend credibility to the ludicrous Reagan-era atom-bomb-pumpe-X-ray-lasers-from-space project. Of course, none of Peter Hagelstein's other la-la-land technology dreams have been founded in reallity either. (Take a look at his constant refrains about how there really is something to cold fusion, scrambling unrelated pieces of irreproducible research results to claim that it *must* be a working, coherent whole, if only people would throw more money down that set of unrelated pits.)

For fusion, at least thermal based fusion, the temperatures used would be thousand times that what is needed to ionize hydrogen or helium. So the fuel is fully ionized through the majority of the plasma in most fusion setups, with the hard part being keeping plasma hot and dense enough so there is time for nuclei to collied and fuse. Higher atomic number elements would be harder to fully ionize, but also would require higher temperatures for fusion anyway.

Although the problem with larger elements, is they radiate a lot of energy, turning thermal energy into light that easily escapes the thin plasma in magnetic confinement plasmas. Even though the core of a fusion plasma is hot enough to fully strip most iron ions, there are still a few around, and more so on the colder edges of the plasma, and it is a major source of energy loss from the plasma. Usually this is dealt with by just being careful what materials are introduced to the plasma, so there are fewer impurities to worry about in the first place, although there are cases where the cooling is used constructively, with impurities added if they can be kept to specific regions. Fully ionizing them could help some, but I highly doubt the process of generating these x-rays would be anywhere near the power level needed to make that a net gain, and will be that way for a long time. And if they could get the particle accelerator component used in the FEL much more efficient, it might mean is more of an option than using muon-catalyzed fusion would be a more serious thing to consider at that point than shaving off a few percent of the energy loss on a fusion reactor.

Shaking molecules until they lose their electrons? That's called heating. That's how CRTs work.

So, these guys found a way to heat up a bit of material with X-ray lasers... M'kay...

This isn't "heating atoms by making them enter resonance." It's, ah, one of those details that GP was talking about. The part where the inner electrons of large atoms follow many and complicated multi-photon-absorbtion paths to being ionized, which extremely high-spin orbitals as well as a near continuum of high-laying Rydberg orbitals, which mean that slight changes in pulse length, shaping, and frequency will be able to have a large effect on ionization rates.

Let me give you a hint: If there's a paper being published in Nature about it, they probably did not, in fact, "just, like, change the dial, man."

It isn't that hard to get a paper into a Physics Review or PRL, and for some fields, that is kind of the go to journal(s). Many physicists would be happy to publish in Nature and would consider it a step up in publicity. It is not like it makes the science in their paper worse, and I doubt many get rejected from Physics Review and decide to submit to Nature next as a backup.

Tuning a laser to the resonant frequency of a specific atom so that it requires LESS energy to strip electons than theoretically calculated is NOT the same thing as heating the bipolar water molecules in your cup-o-soup while you're on break from workin in the coal mine.


Seems odd that it's x-rays that escape a black hole, though it may be coincidental. Do you think there's a connection, and would you speculate on how many kitchen microwaves it might take to allow this to happen? Or what exactly is resonating in the standard model of xenon. Is it the electrons themselves or is there something about the nucleus that changes, making it a less energetic process by which the electrons are held in orbit around this newly configured mass. Perhaps the photon bombardment has found a harmonic that effects the strong nuclear attraction of protons within their otherwise stable configuration.

I wonder what harmonics are generated.

Or maybe something you don't remember correctly. Hawking radiation that escapes a black hole would be made of a soup of particles that have antiparticles and what they might decay into, so a lot of electrons and neutrinos and gamma rays in the end, although initially it would be just leptons and baryons, not gamma rays. You are probably referring to the x-rays observed and expected to be coming from the accretion disk around a black hole. At that point, any light would escape. The distinction for x-rays, is that the matter falling into a black hole would be heated up quite hot from the friction as the material transfer angular momentum to other material so it can fall in. Hot enough that the blackbody radiation peaks in the x-ray band, something that doesn't happen much elsewhere and is a clear signature that astronomers can look for, not to mention the potential for high resolution imaging as x-ray optics improve. However, structure of the accretion disks can also be studied with radio waves, and may have high resolution imaging from large base line radio telescopes, because the blackbody emission (and other emissions) are across most of the EM spectrum.

Or what exactly is resonating in the standard model of xenon

It is the electron structure, same as multiphoton absorption at lower energies.

Microwave ovens don't use any particular resonance and aren't even near the peak absorption, off by a factor of 10 in frequency from the peak for room temperature water and still off by a factor of 3-4 for boiling water (peak varies from ~100 GHz for 0 C water to ~10 GHz for 100 C water). The frequency used in microwave ovens is determined by what blocks of the spectrum have been allocated for industrial use and economics. It is why in industrial microwave ovens they use 900 MHz, because it is another industrial block and cheaper to make large, high power sources for than 2.4 GHz. For home use, the 2.4 GHz is a little more compact, but cheaper, especially in the past, than jumping up to the 5.8 GHz band. Additionally, putting the food in a metal box so that the microwaves can make several passes without much else to absorb it means that particular efficiency of water is not that important as long as it is much more than the walls (although hot spots when trying to defrost stuff can kind of suck).

That said, this work here is pretty substantial. If you wanted disparage this work, you could have maybe instead have compared it to the large amount of work on multiphoton ionization work done by (non-x-ray) laser material interaction research, as this doesn't have much to do with heating the atoms There has been a lot of work into how multiphoton absorption can trigger and be used for ionization (or to deal with it when it is counter productive). However, there is still a ways to go on the modeling. A couple different models make different assumptions to simplify the quantum mechanics calculations, and the impact and usefulness of those assumptions is still being looked at. Testing these models at much higher energies and ionizations like here is a major step toward that. Maybe that is why the paper spends some effort comparing results to predictive models. And not to say that further optimizing and experimental refinement of the use of LCLS is not noteworthy.

"So you just got the Kinect/Xbox360 gaming system and you're having fun, hanging out in your underwear, plopped down in your favorite lounge chair, and playing games with your buddies. Yeah, it's great to have a microphone and camera in your game system so you can "Kinect" to your pals while you play, but did you read that Terms of Service Agreement that came with your Kinect thingy? No? Here, let me point out an important part of that service agreement.

        If you accept the agreement, you "expressly authorize and consent to us accessing or disclosing information about you, including the content of your communications, in order to: (a) comply with the law or respond to lawful requests or legal process; (b) protect the rights or property of Microsoft, our partners, or our customers, including the enforcement of our agreements or policies governing your use of the Service; or (c) act on a good faith belief that such access or disclosure is necessary to protect the personal safety of Microsoft employees, customers, or the public."

Did you catch that? Here, let me print the important part in really big letters.

"If you accept the agreement, you expressly authorize and consent to us accessing or disclosing information about you, including the content of your communications⦠on a good faith belief that such access or disclosure is necessary to protect the personal safety of Microsoft employees, customers, or the public."

OK, is that clear enough for ya? When you use the Kinect system, you agree to allow Microsoft (and any branch of law enforcement or government they care to share information with) to use your Kinect system to spy on you. Maybe run that facial recognition software to check you out, listen to your conversations, and keep track of who you are communicating with.

I know this is probably old news to some, but I thought I would mention it because it pertains to almost all of these home game systems that are interactive. You have to remember, the camera and microphone contained in your game system have the ability to be hacked by anyone the game company gives that ability to, and that includes government snoops and law enforcement agents.

Hey, it's MICROSOFT. What did you expect?

And the same concerns apply to all interactive game systems. Just something to think about if you're having a "Naked Wii party" or doing something illegal while you're gaming with your buddies. Or maybe you say something suspicious and it triggers the DHS software to start tracking your every word. Hey, this is not paranoia. It's spelled out for you, right there in that Service Agreement. Read it! Here's one more part of the agreement you should be aware of.

        "You should not expect any level of privacy concerning your use of the live communication features (for example, voice chat, video and communications in live-hosted gameplay sessions) offered through the Service."

Did you catch it that time? YOU SHOULD NOT EXPECT ANY LEVEL OF PRIVACY concerning your voice chat and video features on your Kinect box."

"Listen up, you ignorant sheep. Your government is spending more money than ever to spy on its own citizens. That's YOU, my friend. And if you're one of these people who say, "Well I ain't ever done nothing wrong so why should I worry about it?' - you are dead wrong. Our civil liberties are being taken away faster than you can spit. The NSA is working away on its new "First Intelligence Community Comprehensive National Cyber-security Initiative Data Center' to keep track of every last one of us. This thing will be the size of 17 football stadiums. One million square feet, all to be filled with more technology and data storage than you could imagine. And 30,000 spy drones are set to be launched over America which can each stay aloft for about 28 hours, traveling 300 miles per hour. WHY? Why do we want these things in our skies?

The military is now taking a keen interest in the Microsoft Kinect Spy System, the fastest selling electronic device in history. Conveniently self-installed in over 18 million homes, this seemingly innocent game system, armed with facial recognition programming and real-time recording of both sound and video, will be used by our own government to spy on and record us in our own homes.

And it doesn't stop there. Other game systems such as Nintendo's WWII are also being turned into government-controlled spy systems. WHY?

That's the real question. WHY?!!! Why is our own government spending billions and billions of dollars to spy on its own people? To keep us safe? Do you really believe that?"

It is just multiphoton absorption. Instead of exciting/expelling an electron with a single photon of the correct energy, you are hitting it with 3 or 5, etc., photons with a third or fifth of the energy each respectively. The atom absorbs the same amount of energy in either case. And the absorption of multiple photons is much less frequent than single photon absorption, getting substantially worse for more photons. So you need a crap ton more photons to do multiphoton absorption, making it rather inefficient... although possibly more efficient than generating the shorter wavelength needed for single photon absorption.

Nobody Seems To Notice and Nobody Seems To Care - Government & Stealth Malware

In Response To Slashdot Article: Former Pentagon Analyst: China Has Backdoors To 80% of Telecoms 87

How many rootkits does the US[2] use officially or unofficially?

How much of the free but proprietary software in the US spies on you?

Which software would that be?

Visit any of the top freeware sites in the US, count the number of thousands or millions of downloads of free but proprietary software, much of it works, again on a proprietary Operating System, with files stored or in transit.

How many free but proprietary programs have you downloaded and scanned entire hard drives, flash drives, and other media? Do you realize you are giving these types of proprietary programs complete access to all of your computer's files on the basis of faith alone?

If you are an atheist, the comparison is that you believe in code you cannot see to detect and contain malware on the basis of faith! So you do believe in something invisible to you, don't you?

I'm now going to touch on a subject most anti-malware, commercial or free, developers will DELETE on most of their forums or mailing lists:

APT malware infecting and remaining in BIOS, on PCI and AGP devices, in firmware, your router (many routers are forced to place backdoors in their firmware for their government) your NIC, and many other devices.

Where are the commercial or free anti-malware organizations and individual's products which hash and compare in the cloud and scan for malware for these vectors? If you post on mailing lists or forums of most anti-malware organizations about this threat, one of the following actions will apply: your post will be deleted and/or moved to a hard to find or 'deleted/junk posts' forum section, someone or a team of individuals will mock you in various forms 'tin foil hat', 'conspiracy nut', and my favorite, 'where is the proof of these infections?' One only needs to search Google for these threats and they will open your malware world view to a much larger arena of malware on devices not scanned/supported by the scanners from these freeware sites. This point assumed you're using the proprietary Microsoft Windows OS. Now, let's move on to Linux.

The rootkit scanners for Linux are few and poor. If you're lucky, you'll know how to use chkrootkit (but you can use strings and other tools for analysis) and show the strings of binaries on your installation, but the results are dependent on your capability of deciphering the output and performing further analysis with various tools or in an environment such as Remnux Linux. None of these free scanners scan the earlier mentioned areas of your PC, either! Nor do they detect many of the hundreds of trojans and rootkits easily available on popular websites and the dark/deep web.

Compromised defenders of Linux will look down their nose at you (unless they are into reverse engineering malware/bad binaries, Google for this and Linux and begin a valuable education!) and respond with a similar tone, if they don't call you a noob or point to verifying/downloading packages in a signed repo/original/secure source or checking hashes, they will jump to conspiracy type labels, ignore you, lock and/or shuffle the thread, or otherwise lead you astray from learning how to examine bad binaries. The world of Linux is funny in this way, and I've been a part of it for many years. The majority of Linux users, like the Windows users, will go out of their way to lead you and say anything other than pointing you to information readily available on detailed binary file analysis.

Don't let them get you down, the information is plenty and out there, some from some well known publishers of Linux/Unix books. Search, learn, and share the information on detecting and picking through bad binaries. But this still will not touch the void of the APT malware described above which will survive any wipe of r/w media. I'm convinced, on both *nix and Windows, these pieces of APT malware are government in origin. Maybe not from the US, but most of the 'curious' malware I've come across in poisoned binaries, were written by someone with a good knowledge in English, some, I found, functioned similar to the now well known Flame malware. From my experience, either many forum/mailing list mods and malware developers/defenders are 'on the take', compromised themselves, and/or working for a government entity.

Search enough, and you'll arrive at some lone individuals who cry out their system is compromised and nothing in their attempts can shake it of some 'strange infection'. These posts receive the same behavior as I said above, but often they are lone posts which receive no answer at all, AT ALL! While other posts are quickly and kindly replied to and the 'strange infection' posts are left to age and end up in a lost pile of old threads.

If you're persistent, the usual challenge is to, "prove it or STFU" and if the thread is not attacked or locked/shuffled and you're lucky to reference some actual data, they will usually attack or ridicule you and further drive the discussion away from actual proof of APT infections.

The market is ripe for an ambitious company or individual to begin demanding companies and organizations who release firmware and design hardware to release signed and hashed packages and pour this information into the cloud, so everyone's BIOS is checked, all firmware on routers, NICs, and other devices are checked, and malware identified and knowledge reported and shared openly.

But even this will do nothing to stop backdoored firmware (often on commercial routers and other networked devices of real importance for government use - which again opens the possibility of hackers discovering these backdoors) people continue to use instead of refusing to buy hardware with proprietary firmware/software.

Many people will say, "the only safe computer is the one disconnected from any network, wireless, wired, LAN, internet, intranet" but I have seen and you can search yourself for and read about satellite, RF, temperature, TEMPEST (is it illegal in your part of the world to SHIELD your system against some of these APT attacks, especially TEMPEST? And no, it's not simply a CRT issue), power line and many other attacks which can and do strike computers which have no active network connection, some which have never had any network connection. Some individuals have complained they receive APT attacks throughout their disconnected systems and they are ridiculed and labeled as a nutter. The information exists, some people have gone so far as to scream from the rooftops online about it, but they are nutters who must have some serious problems and this technology with our systems could not be possible.

I believe most modern computer hardware is more powerful than many of us imagine, and a lot of these systems swept from above via satellite and other attacks. Some exploits take advantage of packet radio and some of your proprietary hardware. Some exploits piggyback and unless you really know what you're doing, and even then... you won't notice it.

Back to the Windows users, a lot of them will dismiss any strange activity to, "that's just Windows!" and ignore it or format again and again only to see the same APT infected activity continue. Using older versions of sysinternals, I've observed very bizarre behavior on a few non networked systems, a mysterious chat program running which doesn't exist on the system, all communication methods monitored (bluetooth, your hard/software modems, and more), disk mirroring software running[1], scans running on different but specific file types, command line versions of popular Windows freeware installed on the system rather than the use of the graphical component, and more.

[1] In one anonymous post on pastebin, claiming to be from an intel org, it blasted the group Anonymous, with a bunch of threats and information, including that their systems are all mirrored in some remote location anyway.

[2] Or other government, US used in this case due to the article source and speculation vs. China. This is not to defend China, which is one messed up hell hole on several levels and we all need to push for human rights and freedom for China's people. For other, freer countries, however, the concentration camps exist but you wouldn't notice them, they originate from media, mostly your TV, and you don't even know it. As George Carlin railed about "Our Owners", "nobody seems to notice and nobody seems to care".

[3] http://www.stallman.org/ [stallman.org]

Try this yourself on a wide variety of internet forums and mailing lists, push for malware scanners to scan more than files, but firmware/BIOS. See what happens, I can guarantee it won't be pleasant, especially with APT cases.

So scan away, or blissfully ignore it, but we need more people like RMS[3] in the world. Such individuals tend to be eccentric but their words ring true and clear about electronics and freedom.

I believe we're mostly pwned, whether we would like to admit it or not, blind and pwned, yet fiercely holding to misinformation, often due to lack of self discovery and education, and "nobody seems to notice and nobody seems to care".

Schneier has covered it before: power line fluctuations (differences on the wire in keys pressed).

The real attacks which survive disk formats and wipes target your PCI devices and any firmware which may be altered/overwritten with something special. It is not enough to scan your hard drive(s) and thumb drives, the real dangers with teeth infect your hardware devices.

        Shield all cables against leakage and attacks
        Still use an old CRT monitor and beg for TEMPEST attacks?
        Use TEMPEST resistant fonts in all of your applications including your OS?
        Know whether or not your wired keyboard has keypresses encrypted as they pass to your PC from the keyboard?
        Use your PC on the grid and expose yourself to possible keypress attacks?
        Know your network card is VERY exploitable when plugged into the net and attacked by a hard core blackhat or any vicious geek with the know how?
        Search out informative papers on these subjects and educate your friends and family about these attacks?
        Contact antimalware companies and urge them to protect against many or all these attacks?

Do you trust your neighbors? Are they all really stupid when it comes to computing or is there a geek or two without a conscience looking to exploit these areas?

The overlooked threat are the potential civilian rogues stationed around you, especially in large apartment blocks who feed on unsecured wifi to do their dirty work.

With the recent news of Russian spies, whether or not this news was real or a psyop, educate yourself on the present threats which all antimalware scanners fail to protect against and remove any smug mask you may wear, be it Linux or OpenBSD, or the proprietary Windows and Mac OS you feel are properly secured and not vulnerable to any outside attacks because you either don't need an antivirus scanner (all are inept to serious attacks) or use one or several (many being proprietary mystery machines sending data to and from your machine for many reasons, one is to share your information with a group or set database to help aid in threats), the threats often come in mysterious ways.

Maybe the ancients had it right: stone tablets and their own unique language(s) rooted in symbolism.


I'm more concerned about new rootkits which target PCI devices, such as the graphics card and the optical drives, also, BIOS. Where are the malware scanners which scan PCI devices and BIOS for mismatches? All firmware, BIOS and on PCI devices should be checksummed and saved to match with others in the cloud, and archived when the computer is first used, backing up signed firmware.

When do you recall seeing signed router firmware upgrades with any type of checksum to check against? Same for PCI devices and optical drives and BIOS.

Some have begun with BIOS security:

Some BIOS has write protection in its configuration, a lot of newer computers don't.

The room/structure was likely heavily shielded, whereas most civvies don't shield their house and computer rooms. There is more than meets the eye to modern hardware.

how many malware scanners scan bios/cmos and pci/agp cards for malware? zero, even the rootkit scanners. have you checksummed/dumped your bios/cmos and firmware for all your pci/agp devices and usb devices, esp vanity usb devices in and outside the realm of common usb devices (thumbdrives, external hdds, printers),

Unless your computer room is shielded properly, the computers may still be attacked and used, I've personally inspected computers with no network connection running mysterious code in the background which task manager for windows and the eqiv for *nix does not find, and this didn't find it all.

Inspect your windows boot partition in *nix with hexdump and look for proxy packages mentioned along with command line burning programs and other oddities. Computers are more vulnerable than most would expect.

You can bet all of the malware scanners today, unless they are developed by some lone indy coder in a remote country, employ whitelisting of certain malware and none of them scan HARDWARE devices apart from the common usb devices.

Your network cards, sound cards, cd/dvd drives, graphics cards, all are capable of carrying malware to survive disk formatting/wiping.

Boot from a Linux live cd and use hexdump to examine your windows (and *nix) boot sectors to potentially discover interesting modifications by an unknown party.

Memorable quotes for Looker (1981) http://www.imdb.com/title/tt0082677/quotes [imdb.com]

"John Reston: Television can control public opinion more effectively than armies of secret police, because television is entirely voluntary. The American government forces our children to attend school, but nobody forces them to watch T.V. Americans of all ages submit to television. Television is the American ideal. Persuasion without coercion. Nobody makes us watch. Who could have predicted that a free people would voluntarily spend one fifth of their lives sitting in front of a box with pictures? Fifteen years sitting in prison is punishment. But 15 years sitting in front of a television set is entertainment. And the average American now spends more than one and a half years of his life just watching television commercials. Fifty minutes, every day of his life, watching commercials. Now, that's power."

"The United States has it's own propaganda, but it's very effective because people don't realize that it's propaganda. And it's subtle, but it's actually a much stronger propaganda machine than the Nazis had but it's funded in a different way. With the Nazis it was funded by the government, but in the United States, it's funded by corporations and corporations they only want things to happen that will make people want to buy stuff. So whatever that is, then that is considered okay and good, but that doesn't necessarily mean it really serves people's thinking - it can stupify and make not very good things happen." - Crispin Glover: http://www.imdb.com/name/nm0000417/bio [imdb.com]

"It's only logical to assume that conspiracies are everywhere, because that's what people do. They conspire. If you can't get the message, get the man." - Mel Gibson (from an interview)

"We'll know our disinformation program is complete when everything the American public believes is false." - William Casey, CIA Director

"The real reason for the official secrecy, in most instances, is not to keep the opposition (the CIA's euphemistic term for the enemy) from knowing what is going on; the enemy usually does know. The basic reason for governmental secrecy is to keep you, the American public, from knowing - for you, too, are considered the opposition, or enemy - so that you cannot interfere. When the public does not know what the government or the CIA is doing, it cannot voice its approval or disapproval of their actions. In fact, they can even lie to your about what they are doing or have done, and you will not know it. As for the second advantage, despite frequent suggestion that the CIA is a rogue elephant, the truth is that the agency functions at the direction of and in response to the office of the president. All of its major clandestine operations are carried out with the direct approval of or on direct orders from the White House. The CIA is a secret tool of the president - every president. And every president since Truman has lied to the American people in order to protect the agency. When lies have failed, it has been the duty of the CIA to take the blame for the president, thus protecting him. This is known in the business as "plausible denial." The CIA, functioning as a secret instrument of the U.S. government and the presidency, has long misused and abused history and continues to do so." - Victor Marchetti, Propaganda and Disinformation: How the CIA Manufactures History

George Carlin:

"The real owners are the big wealthy business interests that control things and make all the important decisions. Forget the politicians, they're an irrelevancy. The politicians are put there to give you the idea that you have freedom of choice. You don't. You have no choice. You have owners. They own you. They own everything. They own all the important land. They own and control the corporations. They've long since bought and paid for the Senate, the Congress, the statehouses, the city halls. They've got the judges in their back pockets. And they own all the big media companies, so that they control just about all of the news and information you hear. They've got you by the balls. They spend billions of dollars every year lobbying lobbying to get what they want. Well, we know what they want; they want more for themselves and less for everybody else.

But I'll tell you what they don't want. They don't want a population of citizens capable of critical thinking. They don't want well-informed, well-educated people capable of critical thinking. They're not interested in that. That doesn't help them. That's against their interests. They don't want people who are smart enough to sit around the kitchen table and figure out how badly they're getting fucked by a system that threw them overboard 30 fucking years ago.

You know what they want? Obedient workers people who are just smart enough to run the machines and do the paperwork but just dumb enough to passively accept all these increasingly shittier jobs with the lower pay, the longer hours, reduced benefits, the end of overtime and the vanishing pension that disappears the minute you go to collect it. And, now, they're coming for your Social Security. They want your fucking retirement money. They want it back, so they can give it to their criminal friends on Wall Street. And you know something? They'll get it. They'll get it all, sooner or later, because they own this fucking place. It's a big club, and you ain't in it. You and I are not in the big club.

This country is finished."

Nucleus Stabilisation via Electron Orbitals (3, Interesting)

Anonymous Coward | more than 2 years ago | (#41955239)

Dysprosium was one of the first elements to be tinkered with in this way.
Odd thing is , that stable nuclei can become unstable as electrons are removed.
The electron cloud is in some way involved in conserving the nucleus.

What "supercharged particles"? (2)

K. S. Kyosuke (729550) | more than 2 years ago | (#41955291)

Is this the same thing that we called "highly ionized" when I was younger? The writing of the article is atrocious, I have the feeling that somebody was gleefully playing with words like a small child. There is no such thing as "very highly charged plasma" - at least comparatively, compared to the total number of free charge carriers - ions and free electrons. It it were, the whole thing wouldn't simply hold together. Plasma is outwardly electrically neutral, or almost neutral.

Re:What "supercharged particles"? (1)

baffled (1034554) | more than 2 years ago | (#41955573)

IANAP, but if what you say is accurate, it seems 'highly charged plasma' would consist of more free electrons per ion on average.. Effectively, more electrons are stripped from the atoms. Which is precisely what it says in the article. I was also confused by the use of the term "supercharged", as it appears to connote highly charged, and not the "supercharge" related to supersymmetry.

I am surprised the data they gathered here is new. It would seem prudent for scientists to gather data on the absorptance spectrum for all elements, ever since these properties were first discovered. Some kind of frequency-varying emitter & charge detection mechanism to generate the data. Perhaps this is an effect that requires stable, precise frequencies that would be impractical to discover over a wide-range of frequencies for all elements?

Re:What "supercharged particles"? (0)

Anonymous Coward | more than 2 years ago | (#41958909)

Fine, what if they use an electromagnetic field to induce separation between the positively charged nuclei and the resultant electron cloud? You could call the nuclei cluster an anti-plasma of highly charged particles, if that will make you feel any better.

Which it won't...

Re:What "supercharged particles"? (1)

K. S. Kyosuke (729550) | more than 2 years ago | (#41960423)

Good luck with trying to do that. Electromagnetic interaction will kick your butt.

Re:What "supercharged particles"? (1)

Anonymous Coward | more than 2 years ago | (#41959639)

While plasma in most situations is roughly neutral, it is not inherently so. Research in non-neutral plasmas is an active field. The most practical application currently is understanding charged particle beams and their use in things from accelerators to some kinds of microwave generating sources. Additionally, research is done on low temperature trapped charged particles, for uses such as measuring fundamental particle and atomic properties, test beds for antimatter storage, or research into dynamics (interesting stuff like low temperature "plasma crystals" when the particles spread out and take an ordered form). This is a rather minor component of plasma physics in general though, so most of the time, plasma physics simplifies things by assuming quasineutrality in many situations where the plasma is obviously neutral.

And when I hear "highly ionized," I usually associate that with a high ionization fraction for a given ionization state, not that the ions each are highly ionized. Maybe they were trying to refer to a plasma that was disassociated disproportionately to its temperature, a form of thermal non-equilibrium, although I've never heard that terminology used before.

IANAPP, but have been a = average musician for a while, and from what i gather from TFA, they're creating a resonance that "maximizes the loss of electrons in a sample". It looks to me as if they've found a "harmonic" frequency for a given Element, that can either be used to coerce electrons out, or avoid as they need. I used all those words broadly, i'm just trying to picture it. The idea of Quanta is something that has always had me going in circles. Max Planck Ftw.

This procedure... (0)

...is very unlikely to cause a resonance cascade scenario.
