Geobel模型的ECRIT离子源性能计算分析
ECRIT Ion Source Performance Analysis based on Geobel Model
摘要
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.关键词
