| 摘 要： | A 2D-3V implicit immersed-finite-element particle-in-cell(IFE-PIC) model is introduced to investigate the radio-frequency(RF) self-bias accelerating system applied in the RF ion thruster.A set of holes in a two-grid system with slit apertures is simulated in Cartesian coordinates. The characteristics of the plasma plume, such as the ion density, the neutralization rate and the ion and electron current density were investigated for different RF voltage amplitudes(600-1200V) and frequencies(6-30 M...
