| 摘 要： | ATON是20世纪90年代新提出的一种Hall推力器设计方案,其中的缓冲区是ATON新采用的一种结构.本文对缓冲区的作用进行分析,在此基础上提出了采用附加电源提高缓冲区预电离率的方法.并采用PIC(Particle-in-cell)粒子模拟方法对这种设计方式的等离子体分布进行数值模拟.结果表明,通过增加缓冲区内的附加电压,能够有效地提高缓冲区预电离率.

| Abstract: | ATON is a new type of Hall thruster proposed in the 1990s, while the buffer chamber is a new structure used in it. In this paper, the main functions of buffer chamber are analyzed, and the method by adopting additional electric source is proposed to increase the preionization rate. Then the particle in cell method is used to simulate the plasma behavior in it. The numerical results show that additional electric power source can increase preionization rate effectively. |
