Abstract
The effect of wall material on volume production of H- ions in a multicusp ion source has been investigated experimentally. 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 strongly on the source pressure of hydrogen gas.Keywords
