摘要：

High-energy ions in the plume of Hall thrusters can affect a spacecraft by sputtering, deposition contamination, or deflection torque. Thus, the plume divergence angle is an important aspect to evaluate for the application of Hall thrusters. Because of the variation in the plume divergence angle measurement with different measuring radii when the arc measurement method is adopted, a torus-source model was established in this study for error analysis. This variation, because of the different gyration radii, was analyzed, and a corresponding correction method was proposed. In addition, the accuracy and scope of the arc measurement method were improved. Published by the AVS.
