Ion and fast neutral bombardment of surfaces in controlled fusion devices

PDF Version Also Available for Download.

Description

The erosion of ferrous- and nickel-alloy walls in fusion reactors from impinging, energetic D, T, He, and Ar ions and neutrals is discussed. The two major machanisms of erosion are sputtering and blistering. Pertinent data are reviewed to obtain estimated or experimental sputtering yields in the energy range 100 eV to 10 keV. The spuntering coefficients for Ar, He, and T are roughly 10/sup 2/, 10, and 1.5 times the value for D (at the same energy). Erosion from blistering is unimportant for Ar, unexamined for D or T, and probably comparable to sputtering for ~10-keV He. (auth)
