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 .
Schematic of a Hall-effect thruster. Hall-effect thrusters accelerate ions by means of an electric potential between a cylindrical anode and a negatively charged plasma that forms the cathode. The bulk of the propellant (typically xenon) is introduced near the anode, where it ionizes and flows toward the cathode; ions accelerate towards and ...
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.
A thruster is a spacecraft propulsion device used for orbital station-keeping, attitude control, or long-duration, ... Hall effect thruster, a type of ion thruster;
A Hall-effect thruster (HET) is a device that is used to propel some spacecraft, after it gets into orbit or farther out into space. In the HET, atoms are ionized and accelerated by an electric field.
Busek's BHT-200 hall effect thruster. The first US Hall thruster flown in space, Busek's BHT-200, was launched aboard the Air Force Research Laboratory's (AFRL) TacSat-2 satellite. The Busek thruster was part of the Microsatellite Propulsion Integration (MPI) Experiment and was integrated on TacSat-2 under the direction of the DoD Space
The Power and Propulsion Element (PPE) for the Lunar Gateway will have a mass of 8-9 metric tons and will be capable of generating 50 kW [3] of solar electric power for its Hall-effect thrusters for maneuverability, which can be supported by chemical monopropellant thrusters for high-thrust attitude control maneuvers.
