英文摘要The optimization design and accurate performance prediction of a radio frequency ion thruster require coupled analysis of the discharge chamber and grided acceleration. In this numerical simulation study, the three-dimensional grid structure is reduced to an axisymmetric model through the equivalent transmittance method, enabling self-consistent simulation of the overall structure of the thruster. A particle-in-cell Monte Carlo collisions (PIC-MCC) method is implemented to investigate a 45 W xenon RF ion thruster operation, and obtain the spatial distributions of the magnetic field, the electric field, the potential, and the plasma parameters in the discharge chamber and the plume region. This approach conveniently correlates the upstream plasma generation process and downstream beam acceleration. Through combined theoretical analysis and numerical simulation, the electron energy absorption mechanism is elucidated, i.e. the RF coil generates the axial magnetic field through the current of a certain frequency, and further induces the azimuthal electric field, which causes the absorbed power to oscillate at a two-fold frequency due to the phase difference between the induced electric field and the current. The change of the absorbed energy of the electrons from the time-varying electromagnetic field causes the periodic change of the ionization rate and potential. Comparative analysis of the ion velocity and ion energy flux distribution before the screen grid and after the acceleration grid reveals that increasing RF power from 18 W to 45 W enhances discharge chamber plasma density while the degree of ionization at the grid exit rises from 15.37% to 32.83%. Concurrently, the grid sheath potential increases, improving the extracted ion beam occupancy ratio and focusing effect and ultimately enhances the thrust and specific impulse. The mass utilization and thrust efficiency of the thruster increase linearly with RF power.
