Experimental study of plasma-surface interaction and material damage relevant to ITER type i ELMs

Experimental study of plasma-surface interaction and material damage relevant to ITER type i ELMs

The paper presents experimental investigations of main features of plasma-surface interaction and energy transfer to the material surface in dependence on plasma heat loads. The experiments were performed with QSPA repetitive plasma pulses of the duration of 0.25 ms and the energy density up to 2....
