Abstract

We report in-situ measurements of the changes in surface composition of 305 stainless steel exposed to the first plasma discharges in PLT. Auger electron spectroscopy of pre-exposure surfaces shows a contamination by carbon and smaller amounts of oxygen. Surfaces subjected to increasing levels of plasma exposure show a substantial decrease of the carbon coverage, increased fractional-monolayer coverages of oxygen and iron and tenth-monolayer quantities of chlorine and sulfur.
