Hall-effect thruster - Wikipedia
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.

Innovators at NASA's Glenn Research Center have developed new technologies that increase the operational lifetime of a Hall effect thruster (HET), which is used primarily on Earth-orbiting satellites and can also be used for deep-space robotic vehicles.
The Propulsion We’re Supplying, It’s Electrifying - NASA
2020年10月22日 · A combination of electric and magnetic fields (Hall effect thruster) or an electrostatic (gridded ion) field then accelerates the ions and pushes them out of the thruster driving the spacecraft to tremendous speeds over time. And instead of fire, its exhaust is a glowing greenish-blue trail, like something straight out of science fiction.
Hall thrusters are electrostatic ion accelerators in which the grid system (which serves in classical ion engines to anchor the negative charges used to accelerate the ions) is replaced with a relatively strong magnetic field perpendicular to the flow.
Pushing the Limits of Sub-Kilowatt Electric Propulsion Technology …
2024年4月23日 · After many years of research and development, researchers at NASA Glenn Research Center (GRC) have created a small spacecraft electric propulsion system to meet these needs—the NASA-H71M sub-kilowatt Hall-effect thruster.
Hall Effect Thruster (HET) uses crossed electric and magnetic fields to generate and accelerate ions to tens of kilometers per second. This efficient form of spacecraft electric propulsion (EP) may be used for orbit maintenance, orbit raising, interplanetary transfers, and other applications. 1 The first American HET to fly in space
The Hall effect thruster (HET) relies on the deflection and trapping of gaseous electrons in the presence of a strong mag-netic field. The simplest expression of the Hall effect, as orig-inally discovered in semiconductors, arises when electrons …

2023年10月4日 · These thrusters use the Hall effect, a phenomenon discovered by Edwin Hall in 1879, to generate thrust by accelerating ions. They are commonly used in spacecraft propulsion systems, offering several advantages over traditional chemical propulsion systems.
Concept and design of a hall-effect thruster with integrated …
2022年11月4日 · Hall-effect thrusters (HETs) are among the most commonly used propulsion systems for attitude and orbit control of satellites. As an arrangement in a cluster or individually, equipped with a mechanical suspension, thrust in all three spatial directions can be generated, but requires additional mechanisms and components.
