摘要：

The effects of low power discharge cleaning on wall conditions in the ISX-A tokamak have been studied in detail. It was found that discharge cleaning caused very little transport of metals and reduced the surface oxygen content on stainless steel samples located between the limiter and the wall to substoichiometric levels. On the other hand, carbon, in the form of a metallic carbide, increased during dishcarge cleaning. The cleanliness of tokamak plasmas obtained after about three weeks of discharge cleaning has been clearly correlated with improvements in the wall conditions and with the reduced level of residual gas species.
