WebStationary Plasma Thruster (SPT)-100 Hall thruster plume calculated using the Electric Propulsion Interactions Code (EPIC) [6,8] is shown in Fig. 8-5. As was the case for ion thrusters, the measured secondary ion fluxes were an order of magnitude less than fluxes measured in ground-based chambers, but, again, in good agreement with plume models. 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.

WebApr 6, 2024 · These spacecraft used ion thrusters. Hall thrusters, by contrast, use a simpler design, with a magnetic field to confine the flow of propellant. These thrusters were invented in the Soviet Union ... WebDec 14, 2024 · In fiscal year 2015, researchers successfully tested a new 12.5-kilowatt Hall thruster that employs magnetic shielding, enabling it to operate continuously for years — a capacity important to deep-space …
WebDec 6, 2000 · authors classify Hall effect thrusters as electromagnetic while others classify it as electrostatic. The most common classification scheme is by the means in which the working fluid is accelerated up to exhaust velocity. However, alternate schemes divide the techniques by the means for ion production
