Crystal stress dynamics by means of nanosecond time-resolved x-ray diffraction Academic Article uri icon

abstract

  • Time-resolved transient lattice deformation in Pt (111) crystal has been directly observed from the shift of a nanosecond x-ray diffraction rocking curve. The development of a tabletop nanosecond x-ray system, which consists of an excimer laser, x-ray diode, and charge coupled device detector is described. With this system, we observed the time-dependent strain distribution during the laser heating process in the bulk of a Pt (111) crystal. This method provides a means of relative low cost for the study of fast transient properties and structures of materials. © 1997 American Institute of Physics.
