Abstract

High speed imaging of the thruster startup revealed a bright ionization period which settles into steady operation over ~50 μs. The cathode introduces azimuthal asymmetry which persists for ~30 μs into the ignition. In steady-state operation, this azimuthal non-uniformity disappears, while breathing ionization oscillations ~ 11 kHz can be observed. On high speed images, these oscillations manifest themselves as azimuthally symmetric oscillations in visible spectrum. Visual identification of the discharge non-uniformity at the ignition is relevant for practical applications of the Hall thrusters on satellites, and laboratory experiments with fast current interrupters.
