摘要

采用heen EQP300型离子分析仪，采用简化重复放电点火的Ga-In液态金属阴极，在真空间隙放电击穿和电弧模式下，测量了阴极点等离子体中不同离子种类的离子能量分布。在电弧放电模式下，离子的平均电荷随放电电流的增大而增大。这种趋势在放电击穿模式中是不存在的。

Cathode spot plasma parameters in the breakdown stage of vacuum discharge

Ion energy distributions of different ion species in cathode-spot plasma were measured with using the HIDEN EQP300 analyzer in both the breakdown and arc modes of discharge in a vacuum gap with the Ga-In liquid-metal cathode simplifying repetitive discharge ignition. In the arc mode of discharge, the average charge of ions rises with increase of discharge current. This trend was found to be absent in the breakdown mode of discharge.
