Conventional electric propulsion systems have some problems about the lifetime due to the erosion of electrodes caused by contacts between electrodes and the plasma. In order to solve this problem and realize the infinite life-time electric thrusters, we aim for a development of a completely electrodeless electric thruster. We have constructed a laboratory model of the electrodeless plasma thruster adopting the Lissajous plasma acceleration and a thrust stand to measure the electromagnetic thrust for validating our plasma acceleration concept. In this paper, we report the designing of the magnetic circuit using permanent magnets and the thrust stand. And the result of the thrust stand calibration and the progress of the thrust measurements are reported.
