论文摘要
在这项研究中，在Raijin推进器中评估了壁离子损失和侵蚀率。这项工作的新颖性是对测得的防护环（金属通道壁）电流的详细分析，这可以快速评估壁离子损失和侵蚀速率。防护圈电流的电流 - 电压特性表明，防护环上的鞘位于离子饱和度状态下，并且罩环电流可用作壁离子通量指示器。实验结果表明，随着加速度区域的转移，Raijin推进器的磁性构型可以显着降低壁离子损耗。
In this study, wall ion loss and erosion rate are evaluated in the RAIJIN thruster. The novelty of this work is the detailed analysis of measured guard-ring (metallic channel wall) current, which enables a fast evaluation of the wall ion loss and erosion rate. The current-voltage characteristics of the guard-ring current indicate that the sheath on the guard rings is in the ion saturation regime and that the guard-ring current can be used as a wall ion flux indicator. The experimental results demonstrate that the wall ion loss can be significantly reduced in the magnetic configuration of RAIJIN thrusters with the acceleration zone shifting.
