Abstract
A D− surface‐conversion source using a solid barium converter is designed for steady‐state operation to produce 200 mA of D−. A similar ion source of twice the size as the one discussed here will meet the requirements set by the present US‐ITER neutral beam injector design. Among the possible types of ion sources being considered for the US‐ITER neutral beam design, the barium converter surface‐conversion source is the only kind that does not use cesium in the discharge. This absence of cesium will minimize the number of accelerator breakdowns.Keywords
