Title: The effect of the H{sub 2} density on the electron energy distribution in H{sup −} ion sources

The electron energy distribution in H{sup −} ion sources is studied. By three-dimensional Monte Carlo simulations (3D-MCC) and cross sections of collisions, the crucial collisions in the JAEA 10A are chosen to develop theoretical models for the low electron temperature and the high electron temperature, respectively. The effects of the H{sub 2} density on the low electron temperature and the high electron temperature in H{sup −} ion sources are predicted with analytic expressions and verified by 3D-MCC. The results show that both the low and high electron temperatures become lower while n{sub H2} increases.
