Magnetic shielding of walls from the unmagnetized ion beam in a Hall thruster

A new 15kW high power Hall thruster is being developed to support a Solar Electric Propulsion Technology demonstration mission within the ISP project. One of the key design features for the new thruster will be the use of magnetic shielding for improving thruster life by shaping the magnetic field to reduce discharge channel wall erosion.
