Microscopic Damage of Tungsten and Molybdenum Exposed to Low-Energy Helium Ions

Polycrystalline tungsten（W）and molybdenum（Mo）materials both non-annealed and annealed at temperatures of 800-1750~C have been irradiated with low-energy（220 eV）,high-flux（~10~（21）ions/m~2.s）He~＋at an irradiation temperature of 600℃and at a dose of1.0×10~（25）ions/m~2.This non-destructive conductive a...
