Characterization and measurement of doubly charged ions in xenon ion thruster beam

摘要

摘要: 为了对离子推力器束流中双荷离子比例进行快速评估，采用放电室经验理论模型通过实验参数获得放电室等离子体参数，根据单、双荷氙离子的不同产生过程，计算得到束流中双/单荷离子密度比.针对兰州空间技术物理研究所20cm氙离子推力器进行了实验，使用E×B探针束流诊断系统获取了束流中双/单荷离子的平均比率.结果表明：在额定工况下理论计算值为0.071与测试结果为0.077符合良好.

Abstract: In order to evaluate the proportion of double ion ratio in ion engine beam rapidly, discharge chamber parameters were obtained through empirical theory, ratio of doubly/singly charged ions in beam was derived based on different generating processes of singly and doubly charged xenon ions. 20cm xenon ion thruster of Lanzhou Institute of Physics was tested and average fraction of doubly charged ions was acquired through E×B spectrometer. Xe++/Xe+ ratio under standard condition was measured to be 0.077, which was in good agreement with the analysis result of 0.071.
