Influence of matching network and frequency on the effective quality factor and performance of a miniature radio frequency ion thruster

The radio frequency ion thruster (RIT) is an electric propulsion device that utilizes (RF) power to ionize propellants; thus, its performance influenced by the and matching network of RF. In this study, L&T type wide-range was employed experimentally investigate a miniature RIT with 4 cm diameter at different frequencies. experimental results show changing parameters same leads changes in effective quality factor varying performances thruster; under similar factors, does not significantly affect however, plasma resistance exhibits dependence. As increases, collision leading increase resistance, which beneficial for improving high Finally, set methods quickly comparing RITs summarized based on factor. These research are also instructive ionization induction-coupled discharge devices other sizes.
