World's First X-Ray Laser Goes Live

Posted by timothy on from the bring-x-rays-back-to-shoe-stores dept.

smolloy writes "The world's first X-ray laser (LCLS) has seen first light. A Free Electron Laser (FEL) is based on the light that is emitted by accelerated electrons when they are forced to move in a curved path. The beam then interacts with this emitted light in order to excite coherent emission (much like in a regular laser); thus producing a very short, extremely bright, bunch of coherent X-ray photons. The engineering expertise that went into this machine is phenomenal — 'This is the most difficult light source that has ever been turned on,' said LCLS Construction Project Director John Galayda. 'It's on the boundary between the impossible and possible, and within two hours of start-up these guys had it right on.' — and the benefits to the applied sciences from research using this light can be expected to be enormous: 'For some disciplines, this tool will be as important to the future as the microscope has been to the past,' said SLAC Director Persis Drell."

    Can it give me super powers if it accidentally hits me?!

      It can give you the power to roll around on the ground and crap yourself. Does that count?

      The way it works in old comics, a ray gun gives the *shooter* power. But what good is a ray gun that shoots right through stuff? Won't the ray from my gun just circle around past the end of the universe and hit me in the back, like having sex with my girlfriend's sister?

      Where can I pickup my free Electron Laser? Will they be ad-supported (watch an ad before you get to fire the laser) or is there a 'pro' version?

      Yes. It can make you disappear instantly. But only the one time.

    But once they ship it off to Taiwan for mass production that two miles will become two centimeters. And we'll all have our own X-Ray laser pointer.

    HA. Typical non-mad scientists thinking! you will never get anywhere thinking like that!
    The question is, "SO when will there be a shark large enough to mount this on?"

    and that would be next week.
