We measured the energy spectrum and the angular distribution of the continuous x-ray radiation of plasma produced by picosecond ruby laser pulses at a flux density of ~1014 W/cm2 at the surface of the target. The effective temperature of epithermal electrons reached 5 keV in massive targets made of different metals.
