摘要: High frequency fluctuations (up to 50 MHz) in the ion current arc voltage and plasma floating potential have been studied, together with influence of surface history on these for currents ranging from 2 A. In process conditioning by repeated arcs, amplitude increases. The a signal grounded probe situated at distance
