Abstract:
A detailed characterization and optimization of the experimental conditions for efficient production of short pulse X-rays to be used in time-resolved experiments are presented. Experimental evidence indicating that the production of K-shell holes generating line radiation arises from collisions with non-thermal electrons and that the size of this source is on the order of the laser spot size is discussed. The combination of extremely small source size, high flux, and short time duration are ideal for time-resolved pump-probed X-ray diffraction and spectroscopic studies of crystalline and molecular dynamics.Relativistic generation and characterization of ultrafast x-rays for time-resolved diffraction and spectroscopy
