Investigation of Blistering in Niobium with the Introduction of Helium Ions Having the Energies Expected in a Thermonuclear Reactor

摘要

Annealed polycrystalline niobium targets were used. The niobium was mechanically and chemically polished and ultrasonicated in a special electrolyte. The surfaces of the specimens were treated. The surfaces of the irradiated targets were examined using a scanning electron microscope. (ERA citation 03:020770)
