WebStanford University WebHall thrusters generate thrust by creating and accelerating ionized gas via an electric field. Confined within a finely shaped magnetic field, electrons gyrorotate within the channel until they ionize a neutral atom. The ionized plasma is then accelerated by the electric field to exhaust velocities of greater than 25,000 m/s.
