To liberate Hall thrusters from the drawbacks associated with dispenser hollow cathodes, we construct and experimentally evaluate an outer-coil-type radio frequency (RF) plasma cathode and an inner-coil-type RF plasma cathode. The influence of the coil configuration on the electron-emission characteristics of the RF plasma cathodes is significant. Compared to the inner-coil-type RF plasma cathode, the outer-coil-type RF plasma cathode achieved higher electronemission performance. For the outer-coil-type RF plasma cathode, we obtained an anode current of 3.3 A at an RF power of 140 W, a xenon mass flow rate of 0.3 mg/s, and an anode voltage of 58 V. The anode current is sufficiently high to operate a 1-kW class Hall thruster. The gas utilization factor for the outer-coil-type RF plasma cathode is comparable to that for a conventional dispenser hollow cathode. On the other hand, the electron production cost for the outer-coil-type RF plasma cathode is four times higher than that for the hollow cathode. Thus, there is a need to improve the power consumption for application of RF plasma cathodes to Hall thrusters.
