Experiments have been carried out on the excitation of shock waves with pressure amplitudes up to 3 Mbar by soft χ radiation in lead. The pulsed χ radiation with a power level up to 2 TW/cm2 used for this purpose was generated by the dynamic compression and irreversible heating of the plasma in two-stage Z-pinch targets at the ANGARA-5-1 device. The experimental results are compared with the results of a numerical simulation, which puts the brightness temperature of the plasma at about 80 eV.
