Feedback control of an azimuthal oscillation in the E × B discharge of Hall thrusters

Feedback control of a low-frequency azimuthal wave known as a "rotating spoke" in the E×B discharge of a cylindrical Hall thruster was demonstrated. The rotating spoke is an m = 1 azimuthal variation in density, electron temperature, and potential that rotates at about 10% of the local E ×...
