Abstract
As the key component of micro electron cyclotron resonance (ECR) ion thruster, the initial gas discharge and electron beam extraction performance of ECR neutralizer plays an important role in the whole performance of ECR ion thruster. The experiment on the neutralizer is completed to study the influence of the antenna structure, cavity length and electronic extraction board on the performance. The experimental results show that, within a certain range, as the length of the cavity is longer, the annular segment of antenna is slightly higher than ECR zone and the width of annular segment is smaller, the performance of the neutralizer is better. There is a reasonable structure for the electronic extraction board to make the performance of the neutralizer better. According to the experimental results, the optimal structure of the neutralizer is determined. For Xe gas, when the microwave power is 2.0W and the gas flow rate is 0.2sccm, the best performances of the optimal neutralizer are that extracted electron beam and coupling voltage is 4mA and 31.5V respectively.
