LCLS-II will be able to produce images of atoms a million times a second. 🔦 engineering
epartment of Energy's SLAC National Accelerator Laboratory are putting the finishing touches on what will become the world's brightest laser., it will be 10,000 times brighter than the brightest laser before itself, once it becomes operational.
"I think it's absolutely fair to say that the LCLS-II will usher in a new era of science," Dr. James Cryan, a staff scientist at SLAC toldThe new laser is"capable of making pulses all the way down below a femtosecond. A femtosecond is to a second as the second is to the age of the universe." This enormously rapid pulsing ability will enable scientists to conduct experiments never before thought possible.
This beam will then run through a series of alternating magnets to produce X-rays. Scientists can use those X-rays to create what they call"molecular movies". You can think of these as snapshots of atoms or molecules in motion capturing each"image" The predecessor of the new laser observing chemical reactions as they happened, demonstrating the behavior of atoms inside stars, and producing live snapshots detailing the process of photosynthesis. The ability to take images at femtosecond intervals with the new laser will, according to"If you think about a strobe light that goes off 120 times, you see one image. If it goes off a million times in a second, you get a much different image. So you can create a much better movie," he says.
