摘要/Abstract

摘要： 为了详细描述等离子体在放电腔内的产生、演化过程,建立了放电腔内部等离子体流动的二维轴对称全粒子数值模型。在考虑壁面二次电子发射影响的前提下,模拟得到了稳态后放电腔内电磁场、电子与离子数密度,电流密度等一系列参数分布,且与相关实验数据进行了比较,吻合较好。模型得到了实验中难以观测到的放电腔内等离子体的产生、演化过程以及稳态下的分布规律,合理解释了放电腔工作的基本原理。

Abstract: Discharge chamber is the important device of plasma generation in ion thruster. For describing the plasma generation, evolutionary processes of the plasma flow inside the discharge chamber, a two-dimensional axial symmetry full particles numerical model was established. Under the precondition of considering the secondary electrons emission from the wall, a series of physics parameters of plasma distribution were obtained after steady-state, including electromagnetic field, electron and ion number densities, current density and so on, which have good agreement with relative experimental data. The processes of plasma generation, evolutionary and plasma distribution law after steady state are obtained with current full particles model, which are difficult to observe in the experiment. The basic working theory of the discharge chamber is also explained reasonably with the current numerical model.
