Abstract
With the rise of smaller satellites (cubesat, nanosat, etc.) in recent years, the issue of space propulsion has been rethought. Electric propulsion, which allows lower thrust than conventional chemical propulsion, has found a place in this sector thanks to mature technologies such as the Hall effect thruster or the grid thruster. These technologies, which are based on the creation and acceleration of a plasma, have the particular advantage of having a very high specific impulse. The Electron Cyclotron Resonance (ECR) thruster is a new electric thruster technology. A plasma is generated by microwave power deposition. The electrons enter into resonance and their cyclotron spinning motion is converted into axial motion in a magnetic nozzle, accelerating the ions and creating thrust. The technology is very simple in design and has already shown very promising performance. During my internship, I worked on the study of ion dynamics in the magnetic nozzle of the ECR thruster and on the comparison of several thrust measurement diagnostics. I focused on the measurement of the ion current density in the thruster's plasma ejection using Faraday probes and the measurement of thrust using a thrust balance.
