Аннотация:The complex approach combining experimental data on X-ray diagnostics of plasma, the results of the numerical PIC simulation of laser-plasma interaction (namely – fast electron spectra), as well as Monte-Carlo calculation of the resulted X-ray spectrum is presented. Direct comparison of the experimental and simulated X-ray spectra (obtained at laser pulse intensity of 2.5×1018 W/cm2) revealed differences in the mean slope and cutoff of the two spectra. In particular experimental data exhibited twice higher slope. The possible explanations of the observed discrepancies are further discussed
