Temperature gradient in Hall thrusters [PDF]
Applied Physics Letters, 2004 Plasma potentials and electron temperatures were deduced from emissive and cold floating probe measurements in a 2 kW Hall thruster, operated in the discharge voltage range of 200–400 V. An almost linear dependence of the electron temperature on the plasma potential was observed in the acceleration region of the thruster both inside and outside the ...

On the potential distribution in Hall thrusters [PDF]
Applied Physics Letters, 2004 A model of the plasma flow in a Hall thruster channel is developed that takes into account the two-dimensional current conservation effect and relies on some experimental input parameters, such as magnetic field and electron temperature distribution. The model is an attempt to explain the experimentally found nonuniform potential distribution across ...

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.
