Inductive Coupling Discharge Characteristics of a 10-cm Dual-Stage 4-Grid Radiofrequency Ion Thruster

In this study, the numerical simulations are used to simulate the discharge process of a 10-cm dual-stage 4-grid (DS4G) radiofrequency (RF) ion thruster, and the effects of RF coil turns, and electrical parameters on the key plasma parameters inside the discharge chamber are investigated. Thus, the...
