X-ray free-electron laser sets new record for shortest high-energy pulses
Researchers at the Linac Coherent Light Source (LCLS) at the U.S. Department of Energy's SLAC National Accelerator Laboratory have measured the shortest high-energy X-ray pulses ever recorded at an X-ray free-electron laser (XFEL). The pulses had photon energies of about 9 kiloelectronvolts (keV) and clocked in at durations of 100 to 400 attoseconds—mere billionths of a billionth of a second. The…
Researchers at the Linac Coherent Light Source (LCLS) in the United States have measured the shortest high-energy X-ray pulses ever recorded. These pulses, produced by an X-ray free-electron laser, have photon energies of about 9 kiloelectronvolts and durations of 100 to 400 attoseconds. The findings have been published in Nature Photonics.
