Abstract Diagnostics with force probes in plumes of electric propulsion systems for spacecraft (thrusters) are presented. This contribution focuses on showing example measurements with force probes for the most common gridless ion thruster types. The

The characterization of an electric propulsion device cathode is performed in the so-called diode configuration with an external anode. The anode acts as a physical boundary for the cathode plasma discharge; therefore, it influences cathode operation

In this paper, we examine the characteristics of the ISCT100 thruster, a miniature xenon-fueled 100-W permanent magnet Hall thruster (HT) suited for microspacecraft propulsion. The impact of the thruster design upon discharge behavior, ion beam prope

Cathodes are electron sources used for gas ionization and ion beam neutralization in Hall thrusters. A laboratory model of a 5 A-class cathode has been experimentally studied in the so-called diode configuration with a flat metal anode. The cathode d

International audience; The operation of a 250 W low-power Hall thruster called ISCT-200 has been studied using a two-dimensional hybrid model. Two different magnetic field topologies have been tested. One topology is called the unshielded configurat

The low-frequency rotating plasma instability (spoke) in the ISCT200 thruster operating in the wall-less configuration was simulated with a 3 dimensional PIC MCC code. In the simulations an m = 1 spoke rotating with a velocity of 6.5 km/s in the ExB

Magnetic shielding is a specific magnetic topology that can increase the lifespan of Hall thrusters by an order of magnitude. Magnetically shielded thrusters have similar performances as standard unshielded thrusters in the 5–15 kW power range. A c
