Stability study for multi-layered x-ray mirrors under powerful nanosecond laser plasma x-ray radiation

The technique of investigation is described as well as the experimental results on thermal stability of multi-layered Cr/C- and Mo/C-based X-ray mirrors to the X-ray radiation of a laser plasma source of 0.5 + 1.5 keV quanta energies, 1 + 25 ns pulse width and 0.01 + 0.2 J/cm2 energy density. The X-ray pulsed heating of the mirror layers was approximately described by calculations and theoretically providing for the analysis of the experimental data.
