A Tandem, Microwave-Driven Cusp Negative Ion Source

Abstract

A microwave driven source of negative hydrogen ions was assembled and tested. The source consisted of two regions, each with separate plasma conditions. The purpose of this test was to simulate the conditions for optimized negative hydrogen yield reported theoretically. Experimentally, the ion yield followed the general trend of Hiskes' theory, but additional yield was seen by surface conversion processes on the barium cathode.
