Experimental scaling laws for the discharge oscillations and performance of Hall thrusters

V. Giannetti et al.

Summary: In this study, an experimental campaign was conducted on a 20 kW-class Hall thruster prototype to investigate the characteristics and variations of low-frequency discharge current oscillations. Data-driven scaling laws for the salient features of discharge current were proposed. This research is of great significance for understanding the thruster discharge process and optimizing its design.

The origin of the breathing mode in Hall thrusters and its stabilization

T. Lafleur et al.

Summary: The formation of the breathing mode in Hall thrusters is attributed to an ionization instability related to nonlinearity in electron power absorption, where an increase in plasma density enhances the electric field causing a positive feedback mechanism. This results in sustained plasma growth until neutral density decreases to a point where reignition is needed for the process to repeat. A carefully designed external circuit can be used to stabilize the discharge by counteracting the change in axial electric field.

Numerical and Experimental Investigation of Longitudinal Oscillations in Hall Thrusters

Vittorio Giannetti et al.

Summary: This paper presents a synergic experimental and numerical investigation of the breathing mode in a 5 kW-class Hall thruster. The calibrated model can predict the spatio-temporal distributions of the plasma properties with reasonable accuracy based on the discharge current signal. The augmented data obtained through the combination of experiments and calibrated model provides insights into the breathing mode oscillations and the evolution of plasma properties.
