等离子体接触器已被确定为空间站（SS）的基准配置，用于控制表面电势，以消除/减轻与空间环境的有害相互作用。该系统代表了一种两用技术，是美国国家航空航天局（NASA）电推进计划的直接产物，特别是离子推进器系统技术开发工作的成果。等离子体接触器子系统包括等离子体接触器单元、电力电子单元和推进剂管理单元。在这个飞行前开发计划下，这些都将达到实验板或工程模型状态。等离子体接触器的开发工作包括优化接触器的设计和配置、验证其所需的使用寿命，以及对接触器羽流和电磁干扰进行特性描述。为空间站选择的等离子体接触器单元设计是一种封闭式保护极、氙空心阴极等离子体源。本文讨论了空间站等离子体接触器单元子系统的测试结果和开发状况。
Plasma contactors have been baselined for the Space Station (SS) to control the electrical potentials of surfaces to eliminate/mitigate damaging interactions with the space environment. The system represents a dual-use technology which is a direct outgrowth of the NASA electric propulsion program and, in particular, the technology development effort on ion thrustor systems. The plasma contactor subsystems include the plasma contactor unit, a power electronics unit, and an expellant management unit. Under this pre-flight development program these will all be brought to breadboard or engineering model status. Development efforts for the plasma contactor include optimizing the design and configuration of the contactor, validating its required lifetime, and characterizing the contactor plume and electromagnetic interference. The plasma contactor unit design selected for the SS is an enclosed keeper, xenon hollow cathode plasma source. This paper discusses the test results and development status of the plasma contactor unit subsystem for the SS.
