内容記述(抄録等) | Effects of cesium vapor injection on H/sup -/ production in a tandem volume source are studied numerically as a function of plasma parameters. Model calculation is performed by solving a set of particle balance equations for steady-state hydrogen discharge plasmas. The results with a focus on electron temperature and gas pressure dependence on H/sup -/ volume production are presented and discussed. Considering H/sup -/ surface production due to H atoms and positive hydrogen ions, enhancement of H/sup -/ production and pressure dependence of H/sup -/ production observed experimentally are qualitatively well reproduced in the model calculation, where stripping loss in the extraction and acceleration regions is taken into account. For enhancement of H/sup $/production, so-called electron cooling in the source region, as well as in the extraction region, is not so effective if plasma parameters are initially optimized with the use of a magnetic filter.
