“…Presently, such experiments are executed with synchrotron-based x-ray sources 1-5 or with laserplasma-based sources, where phase transitions, 6 phonons, 6-10 nonthermal melting, 11,12 etc. Thereby, the length of the pulses has decreased from a few nanoseconds 14 to hundred picoseconds, 15 and picoseconds. In contrast to synchrotrons, plasma-based sources can be used in small research facilities.…”
