Hall effect thrusters have been classed as both electrostatic and electromagnetic propulsion systems. An electrostatic field accelerates the ions in the propellant stream but that field is, to a large extent, produced by the actions of plasma electrons interacting with a magnetic field, giving both classes a claim to the technique.'
'The Hall thruster, which uses gases like xenon and krypton as propellants, can enable modern spacecraft to travel farther, faster, and cheaper than chemical propulsion technologies. Hall thrusters are currently used for stationkeeping, orbit raising, and life extension on satellites and for main propulsion on deep space probes.'
