摘要

摘要: 利用Geobel模型对电子回旋共振离子推力器的离子源性能进行了计算，分析工质利用率与放电损耗的关系、电子温度与离子源性能的关系、离子源长度和栅极有效透明度对放电损耗和工质利用率的影响。采用Geobel模型对电子回旋共振离子推力器性能的计算结果为：20 cm ECRIT离子源在100 mm轴向长度、80%栅极有效透明度条件下，工质利用率为90%，放电损失为203 W/A；10 cm ECRIT离子源在40 mm轴向长度、80%栅极有效透明度条件下，工质利用率为86%，放电损失为300 W/A。结果表明：采用Geobel模型算法计算结果与国外文献数据的相对误差小于5%，利用该模型对电子回旋共振离子推力器离子源性能分析的方法有效、合理。

Abstract: This paper uses the Geobel model to study the plasma performance of the ion source of an electron cyclotron resonance ion thruster. It analyzes the relationship between mass utilization efficiency and discharge loss, electron temperature and ion source performance, influence of ion source length and grid effective transparency on the discharge loss and mass utilization efficiency. The calculation results of the ion source performance show that the mass utilization efficiency and the discharge loss are 90% and 203 W/A respectively for 20 cm ECRIT ion source with 100 mm axial length and the 80% grid effective transparency; the mass utilization efficiency and discharge loss are 86% and 300 W/A respectively for 10 cm ECRIT ion source with 40 mm axial length and the 80% grid effective transparency. The performance analysis demonstrates that the ion source performance data calculated with the Geobel model has a relative error of less than 5% compared with the data published in the open literature.
