摘要/Abstract

摘要： 为研究圆柱形阳极层霍尔推力器内轮辐效应的不稳定性，利用高速相机和静电探针得到1-2-1模式、1-2-3-1模式和1-2-3-2-1模式的轮辐分裂与合并现象。随着磁感应强度由205Gs增加到225Gs，轮辐个数m由1增加到3。轮辐的分裂与合并模式增多，且轮辐的旋转频率随之由25kHz提高到40kHz~50kHz。轮辐效应的存在是电子密度分布函数的宏观体现，动理论方程中力F的波动引起了轮辐的分裂，随着轮辐个数m的增加，电子分布的低频大幅度波动逐渐演变为小幅度高频率的波动。电子密度分布函数的波动引起的轮辐效应产生了角向分布的电场强度与磁场共同作用，增强了电子轴向漂移运动。

Abstract: In order to study rotating spoke instability in cylindrical anode layer Hall thruster, the spoke splitting and merging phenomena of 1-2-1 mode, 1-2-3-1 mode and 1-2-3-2-1 mode were obtained by using high-speed camera and electrostatic probe. With the increase of magnetic induction intensity from 205Gs to 225Gs, the number of spokes m increases from 1 to 3. There are more modes of spoke splitting and merging, and the frequency of spoke rotation increased from 25kHz to 40kHz~50kHz. The existence of the rotating spoke is the macroscopic reflection of the electron density distribution function. The fluctuation of force F in the dynamic equation causes the splitting of the spoke. With the increase of the number of spokes m, the large fluctuation of the electron distribution in low frequency gradually evolves into a small high frequency fluctuation. The angular electric field intensity produced by the rotating spoke caused by the fluctuation of the electron density distribution function acts together with the magnetic field, which enhances the axial drift motion of the electron.
