内容記述(抄録等)The effect of the wall material on hydrogen ion species productions in a low-pressure plasma, especially H^- ions, is studied experimentally by using a multicusp ion source. Under the same discharge conditions, Al generally produces the highest H^- ion current although the difference in H^- yield between Al, Cu and stainless-steel liners depends on the source pressure of hydrogen gas. At the same time, there is little difference in the plasma parameters for the three different metal liners. The present results suggest that neutral particles (i.e. atomic hydrogen (H) and vibrationally excited molecules (H^*_2))-wall interaction affects those differences in H^- production.
