摘要
Depth profiles of Li-6 implanted into high-melting point rhenium refractory metal has been measured for as-implanted, as well as thermally annealed samples using a non-destructive Thermal Neutron Depth Profiling technique at the LWR-15 research reactor in Rez. The Gaussianlike shape, typical for as-implanted Li-depth profile, is preserved after the thermal annealing at high temperature demonstrating the activation of the Li atom diffusion process at the Re-target. The diffusion coefficient at 1830 degrees C has been evaluated by the comparison of the Li profiles before and after the thermal annealing. This study aims to investigate the applicability of Re metal in ISOL related applications.
