| Abstract: | A hollow cathode is a key assembly for reliability and lifetime of an electric propulsion system. The development of a hollow cathode product depends on test technology to a large degree. Based on an introduction to the test classification and test facility of the hollow cathode, the test technology of a hollow cathode product applicable to electric propulsion system is discussed from performance test, acceptance test, qualification test and lifetime test respectively. It is concluded that the most suitable method of lifetime assessment of a hollow cathode product for either long lifetime or high power electric propulsion system is a combination of practical test and theoretical model. |
