Hall thruster vs ion thruster
WebA mission comparison of solar electric propulsion vehicles with Hall effect and gridded ion thrusters utilizing bismuth, xenon, and krypton propellant options is presented. Three … In spacecraft propulsion, a Hall-effect thruster (HET) is a type of ion thruster in which the propellant is accelerated by an electric field. Hall-effect thrusters (based on the discovery by Edwin Hall) are sometimes referred to as Hall thrusters or Hall-current thrusters. Hall-effect thrusters use a magnetic field to … See more Hall thrusters were studied independently in the United States and the Soviet Union. They were first described publicly in the US in the early 1960s. However, the Hall thruster was first developed into an efficient propulsion … See more The highest power Hall-effect thruster in development (as of 2024) is the University of Michigan's 100 kW X3 Nested Channel Hall Thruster. The … See more The essential working principle of the Hall thruster is that it uses an electrostatic potential to accelerate ions up to high speeds. In a Hall thruster, the attractive negative charge is provided by an electron plasma at the open end of the thruster instead of a grid. A … See more Hall thrusters have been flying in space since December 1971, when the Soviet Union launched an SPT-50 on a Meteor satellite. Over 240 … See more • Edgar, Y. (2009).
