LOW ENERGY HYDROGEN ION EROSION YIELDS AS DETERMINED WITH A KAUFMAN ION SOURCE

摘要

Materials including 304-55, Na,Fe, W, Cu, Si, TiC, SiC, B4C, Be4B, Be2B, Be2C, B, Al203,SiO2, BeO, TiS2, C and BN were eroded at ion energies of 25W,500 and 1000 eV at low temperature (~100-200°C) and high temperatures (~600°C). The hydrogen ion beam was formed in a Kaufman type ion source which gives a large area ion beam and thus allows the erosion yields of a number of materials to be determined simultaneously.
