6 kW Hall thruster in operation at the NASA Jet Propulsion Laboratory. 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.
SPT-140 is a solar-powered Hall-effect ion thruster, part of the SPT-family of thrusters. SPT stands for Stationary Plasma Thruster . [ 1 ] [ 2 ] Like other members of the SPT series, it creates a stream of electrically charged xenon ions accelerated by an electric field and confined by a magnetic field.
An alternate form of electric propulsion, the Hall-effect thruster, was studied independently in the United States and the Soviet Union in the 1950s and 1960s. Hall-effect thrusters operated on Soviet satellites from 1972 until the late 1990s, mainly used for satellite stabilization in north–south and in east–west directions.
Busek has demonstrated experimental xenon Hall thrusters at power levels exceeding 20kW. [9] Busek has also developed Hall thrusters that operate on iodine, [10] [11] bismuth, [12] [13] carbon dioxide, [14] magnesium, [15] zinc, [16] and other substances. An iodine fueled 200 W Busek Hall thruster will fly on NASA's iSat (Iodine Satellite ...
PPS-1350 is a Hall-effect thruster, a kind of ion propulsion system for spacecraft. It was used in the SMART-1 mission to the moon and one geostationary satellites: Inmarsat-4A F4. [1] [2] It creates a stream of electrically charged xenon ions accelerated by an electric field and confined by a magnetic field. [3]
