Or shorter? If it was faster, the units would be a percentage of the maximum velocity of a sheep in a vacuum, Shirley.
Physicists at the University of Central Florida have developed the world's fastest X‑ray pulse, at 53 attoseconds. Blink and you'll really, really miss it. At 53 quintillionths (53 x 10‑18) of a second, the flash is 15 orders of magnitude faster than the blink of an eye. The beam travels less than one-thousandth of the …
Seriously, how awesome is that - 53x10-18 seconds. Incredible. For context, that's close to the time it takes for light to pass 100 Hydrogen Atoms. Just think about that for a second (which is a lot of attoseconds! :P). 100 Hydrogen Atoms. And mankind can create something that precise. It makes you realise that in spite of the efforts of religious fundamentalists, politicians and marketeers, there might actually be hope for humanity after all....
No doubt this has uses, but it's not clear how it can help to "...shoot slow-motion video of electrons and atoms...". However short the pulse, surely an electron which absorbs an X-ray photon will immediately head off at high speed, so won't be around to be "videoed". If the photon isn't absorbed, I assume it just passed by. Can anyone explain?
These guys will even sell you one.
300eV is of course what you need for that "Extreme UV" that people have been touting as the future of narrow line width chip making.
Current systems need a 20Kw laser to generate c10W of "EUV" light to expose a 300mm dia wafer.
I'm guessing but it can also be used for diagnostics on one of those laser fusion systems as well.
I'm more of a fan of phased plasma rifles myself (something in the 40 watt range?).
I do however wonder if this could be used for other purposes like optical switching since the faster the better and all that?
