摘要/Abstract

摘要： 微波霍尔推力器是双极霍尔推力器的一种形式,其电离源中的圆柱谐振腔是一个关键件,它承担着微波能量的传输并激发表面波等离子体的重要作用。正确选择其结构和谐振模态是构建微波霍尔推力器的重要基础。为此,针对不同结构、不同谐振模态的微波谐振腔进行结构参数计算分析和电磁场分布规律数值模拟,从中选取可以和霍尔推力器SPT70加速通道相匹配的腔体结构。计算分析和数值模拟结果表明2.45GHz谐振于TM₀₁₁模的圆柱谐振腔和SPT70加速通道有合适的匹配关系。

Abstract: Microwave Hall thruster is one type of dual stage Hall thrusters. Cylindrical resonant cavity is a key component of plasma source which can compose microwave Hall thruster. The cylindrical resonant cavity will transit microwave energy and generate surface plasma which is formed at the end wall of ceramic acceleration cannel. This function makes the study on the structure and resonant mode of cylindrical cavity very important. Based on the theory of microwave, the calculation and analysis about different resonant cavity structure and numerical simulation about different resonant modes were carried out. From the results of calculation and simulation, a cylindrical cavity resonating at 2.45GHz and TM₀₁₁ mode is found to be the best for microwave Hall thruster.

Key words: Hall thruster; Electromagnetic wave;Microwave resonant cavity⁺
