Numerical and Experimental Investigation of Longitudinal Oscillations in Hall Thrusters
Aerospace, 2021 One of the main oscillatory modes found ubiquitously in Hall thrusters is the so-called breathing mode. This is recognized as a relatively low-frequency (10–30 kHz), longitudinal oscillation of the discharge current and plasma parameters.
