Melt layer macroscopic erosion of tungsten and other metals under plasma heat loads simulating ITER off-normal events

This paper is focused on experimental analysis of melt layer erosion and droplet splashing of tungsten and other metals under heat loads typical for ITER FEAT off-normal events, such as disruptions and VDE’s. Plasma pressure gradient action on melt layer results in erosion crater formation with moun...
