Time-resolved x-ray diffraction study of laser-induced shock and acoustic waves in single crystalline silicon

“…It also lies the basis for the realization of x-ray optical switching devices 29 as they may be used to design Q-switching x-ray resonators and cavities. 17,18 Such devices are valuable developing the equivalent of neutron Bragg reflecting cavities 30 for x-ray free-electron lasers. Last but not the least, these measurements illustrate the path for time-resolved in situ studies on the short and ultrashort time scales relevant to material engineering applications involving shock mechanisms, such as ball-and laser peening.…”

“…The procedure is repeated as many times as needed to achieve sufficient statistics for each time channel. 16,18 The output from a NaI scintillator equipped with a photomultiplier detector was split into a fast channel of Ͻ20 ns jitter and a slow channel for energy discrimination with 100 ns jitter. As shown in Fig.…”

“…Stroboscopic measurements were used to investigate sound fields 15,16 and x-ray optical devices operating at the picosecond time scale. 17,18 Similar stroboscopic techniques were applied to the study of phase transformations occurring over millisecond time scales, where the kinetics of the transformation is determined by the interactions between micrometer sized grains or domains. 19,20 In particular, the use of high-energy x rays has allowed probing of bulk samples and collection of nanosecond x-ray diffraction data from laser-shock compressed solids, at different stages of the wave propagation, thus overcoming the limitations due to back surface measurements.…”
