The role of arcing in producing metal impurities in tokamaks

G.M. McCracken, D.H.J. Goodall1978年被引用 68Nuclear FusionIF 3出版社

Measurements have been made of the number of metal atoms deposited on collectors during tokamak discharges in DITE. The amount of metal is shown to be larger than that expected due to sputtering by hydrogen ions and charge-exchange neutrals. It is proposed that arcing is responsible for this metal deposition and direct observation of arc tracks on limiters and probes is described.
