  • Hall effect thruster with anode having magnetic field barrier
    Publication number: 20060076872
    Abstract: An efficiency enhancing anode-magnetic structure of a Hall effect thruster produces a radially directed magnetic field between inner and outer poles at the exit portion of a gas distribution channel. The field-shaping structure includes magnetic material extending alongside the channel with an associated secondary flux-generating component to create an axially directed magnetic field in the area between the anode of the thruster and the exit portion of the gas distribution channel.
