A small radius discharge in hydrogen inductively driven by a planar coil is studied experimentally regarding development of a matrix source of negative hydrogen ions: a matrix of small radius discharges, each of them completed with a magnetic filter and a single aperture extraction device. Probe and laser photodetachment diagnostics are the methods employed. Results for the axial structure of the discharge show the influence of the absorbed rf power, of the magnetic filter (and its position), and of the bias applied to the first electrode of the extraction device on the spatial distribution of the plasma parameters and on the discharge modes.
针对负氢离子矩阵源的发展，对由平面线圈电感驱动的氢气中的小半径放电进行了实验研究：小半径放电矩阵，每个放电都配有磁过滤器和单孔提取装置。采用了探针和激光光致脱附诊断方法。放电轴向结构的结果表明，吸收的射频功率、磁过滤器（及其位置）以及施加到提取装置第一电极上的偏压对等离子体参数的空间分布和放电模式有影响。
