We describe a plasma-cathode electron beam source based on a hollow-cathode discharge that is capable of generating a 9 kW dc electron beam at an accelerating voltage of 20 kV, with helium as a working gas at a pressure of 30 Pa. A test run of ∼50 operational hours did not indicate any significant degradation of the electron source extraction system or other structural components, and we estimate the operational lifetime of the source at about 100-120 h.

前级真空压力等离子体阴极大功率连续电子束源

我们描述了一种基于空心阴极放电的等离子体阴极电子束源,它能够在 20 kV 的加速电压下产生 9 kW 直流电子束,在 30 Pa 的压力下以氦气作为工作气体。约 50 个工作小时的运行并未表明电子源提取系统或其他结构部件的任何显着退化,我们估计该源的工作寿命约为 100-120 小时。
