Abstract

Study of thermal phenomena in various media under irradiation with relativistic electrons is of major importance for key technological areas like processing of materials used in nuclear fusion installations. C and W behavior under irradiation with relativistic electrons was investigated in recent literature. Here we report on the study of the thermal fields generation in double layered C and W samples when irradiated with 6MeV relativistic electron beams. Two cases are considered when first face submitted to irradiation is either C or W, respectively. Experimental results are analyzed in conjunction with theoretical predictions. The experiments were conducted with the ALID electron accelerator facility at National Institute for Lasers, Plasma and Radiation Physics, Bucharest-Magurele while integral transformation method was applied for theoretical analysis. Special attention is paid to the electrons absorption laws by C and W. Semi -empirical approximations from literature were used in this analysis..
