MEASUREMENT AND ANALYSIS OF THE PLASMA ION COST IN THE DISCHARGE OF THE XENON ION THRUSTER

摘要: 离子推力器放电室等离子体离子的产生成本是影响推力器性能优劣的重要参数之一。从理论上分析了影响等离子体产生离子的能量消耗成本的基本因素,同时测量了不同工作条件下离子推力器的等离子体离子能量消耗成本值。试验结果与理论分析取得了良好的一致性。通过对试验结果的分析,得到离子推力器放电室等离子体离子消耗成本的最佳选取点。

Abstract: Plasma ion energy cost is the one of the important parameters.It will affect the performance of ion thrusters.The basis factors were analyzed,which affect plasma ion energy cost from theory.In addition,the plasma ion energy cost has been measured at the different conditions.The experimental results are in good agreement with the theory analogy.The optimal plasma ion energy cost region of ion thrusters has been presented.
