“…The ECR ion engine uses a microwave with a frequency of 4.25 GHz to produce plasma, which is transmitted through the waveguide to the discharge ECR plasma is formed through subsequent electronneutral and electron-ion collisions. JAXA has improved the thrust force of the ECR ion engine by changing the way the propellant is injected [3], [4]. In conventional ECR ion engines, the propellant inlet is located only at the end of the waveguide.…”

“…Moreover, the Japan Aerospace Exploration Agency (JAXA) has been researching and developing an electron cyclotron resonance (ECR) ion engine that can be installed in an asteroid explorer and has also improved its propulsion performance [3], [4]. To improve the performance, JAXA needed to be able to measure the microwave electric-field distribution of the internal plasma in the ion engine during actual operation.…”
