为深入分析霍尔推力器放电通道的非麦氏电子分布对等离子体与壁面相互作用的影响,采用一维非稳态鞘层动力学模型,统计了等离子体与壁面相互作用的重要物理量。结果表明,非麦氏电子分布函数和麦氏电子分布函数下等离子体与壁面相互作用存在很大差异,电子服从非麦氏电子分布时入射电子在壁面上的能量沉积,以及二次电子对主流区电子的冷却作用都明显弱于电子服从麦氏分布的情形。 In order to deeply analyze the influence of non-Maxwellian electron distribution of Hall thruster discharge channels on the interaction between plasma and wall, one-dimensional unsteady sheath dynamics model was used to calculate the important physical quantities of the interaction between plasma and wall. The results show that there is a great difference between the plasma and the wall surface under the non-Maxwell electron distribution function and the Maxwell electron distribution function. The energy deposition of the incident electrons on the wall when the electrons follow the non-Maxwell electron distribution, The cooling effect of the region electron is obviously weaker than that of the electron subject to Maxwell distribution.
