Abstract
Secondary electrons emitted at the dielectric walls of a Hall thruster are accelerated by the sheaths and enter as monoenergetic beams into the main plasma where they are magnetized. This work is focused on the influence of the magnetic field on secondary beams in the low-collisionality limit. First, it is shown that a magnetic field oblique to the walls may have an important trapping effect on the beam. Second, effects of curvature and grad-B drifts, and of magnetic mirror are evaluated on individual particles for magnetic field topologies of Hall thrusters.
