5. Structural Studies Of Materials Using Time-Resolved X-ray Diffraction
Abstract : This work consisted of the application of X-ray diffraction methods to the study of ultrafast phenomena in various materials. Since the X-ray pulses generated from the bending magnet at the MAX II ring, where most of the experimental work was conducted, have a duration of the order of 300 ps, they can not be used directly as probe pulses in experiments where higher temporal resolution is required.
