On the onset of breathing mode in Hall thrusters and the role of electron mobility fluctuations
Frontiers in Physics, 2022 Breathing mode is an ionization instability which is observed ubiquitously in the operation of Hall thrusters. It is recognized as a relatively low frequency (10–30 kHz) longitudinal oscillation of the discharge current and the plasma parameters ...
