Cu target ablation under irradiation with a power tubular beam of relativistic electrons
The structure of the coating formed under condensation of the products of ablation of Cu target irradiated with high-current electron beam of tubular shape, at different distances from the target evaporated has been studied. The features of the evaporation chamber design providing a local increase in current density were considered, and effect of the beam focusing on the structure and microhardness of the surface layers of the target was determined.
