AbstractTo evaluate the durability and the lifetime of carbon materials as plasma facing components against plasma disruption, thermal shock tests were performed using an electron beam test facility. Experimental results show that the weight loss increases with heat flux at a constant absorbed energy. It is found that the erosion depth measured in the experiment is about 2 to 2.5 times larger than that predicted by the numerical analysis. Since solid particle emission is observed during heating experiments, the difference between experimental and numerical results is mainly attributable to the solid particle losses which are not considered in the numerical analysis.
