研究了在小型磁过滤多离子源中，向氢放电中加入铯或氙对氢离子产生的影响。在相同的操作参数下，在氢气放电过程中加入铯蒸汽，使氢的输出增加了16倍。同样，在最佳氢气源压力下，在保持相同电弧参数的情况下，在氢气放电中加入氙气导致氢输出比纯氢气操作增加2.7倍。等离子体电极在最佳偏置电压下工作是获得这一结果的必要条件。
The effect on H− ion production by adding cesium or xenon to a hydrogen discharge, in a small magnetically filtered multicusp ion source, has been investigated. Addition of cesium vapor to the hydrogen discharge resulted in a factor of 16 increase in H− output relative to the uncesiated discharge for the same operating parameters. Likewise, the addition of xenon gas to a hydrogen discharge resulted in a factor of 2.7 increase in H− output over pure hydrogen operation at optimum H2 source pressure, while maintaining the same arc parameters. Operation of the source with the plasma electrode at optimum bias voltage was essential to obtain this result.
