ABSTRACT
The results of numerical simulations of fast electrons interaction with matter, calculated yield and angular distribution of fluorescence K-α X-ray radiation. carried out by ERA and PRIZMA codes lor experiments, on interaction ol ultra-short laser pulses with high-Z targets at intensities of 1016 − 1018 W/cm2 are presented. Spherical targets with conical hollows are proposed for experiments with picosecond lasers to increase the brightness ol the hard X-ray Source.
