Abstract	The main results of numerous experiments carried out during some last years at QSPA-Be facility in Bochvar Institute on the experimental simulation of beryllium damage under intense transient plasma loads are presented. Beryllium and Be/CuCrZr mock-ups of special design were tested by hydrogen/deuterium plasma streams (5 cm in diameter) with pulse duration of 0.5 ms in a heat loads range of 0.2-2.1 MJ/m 2 and maximum quantities of plasma pulses up to 100-250 shots. During the experiments, the mock-ups temperature has been maintained in the range of RT-500°C. Two beryllium ITER grades: TGP-56FW (RF, Bochvar Institute) and S-65C (USA, Materion Brush) were studied in these experiments. Influences of plasma heat loads, surface temperature and quantities of plasma pulses on the Be erosion and surface damage are presented. The experimental data obtained are used for validation of appropriate numerical models and for the estimation of lifetime of the Be armor.
