The cracking thresholds were evaluated for tungsten samples with different microstructure in the course of QSPA Kh – 50 repetitive plasma loads. No damage has been observed on the exposed surfaces under 0.1 MJ/m². Nevertheless, cracks were detected in the bulk of irradiated tungsten (with longitudin...
