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) mission. Busek is also preparing a 600 Watt iodine Hall thruster system for future Discovery ...
Hall-effect thrusters use a magnetic field to limit the electrons' axial motion and then use them to ionize propellant, efficiently accelerate the ions to produce thrust, and neutralize the ions in the plume. The Hall-effect thruster is classed as a moderate specific impulse (1,600 s) space propulsion technology and has benefited from ...
Hall effect devices produce a very low signal level and thus require amplification. The vacuum tube amplifier technology available in the first half of the 20th century was too large, expensive, and power-consuming for everyday Hall effect sensor applications, which were limited to laboratory instruments.

Aerojet qualified a 4.5-kW Hall effect thruster electric propulsion system based on technology licensed from the Busek Corporation. [6] [7] Aerojet is under contract to Lockheed Martin to provide the first two shipsets of the new thruster system for the next generation Advanced Extremely High Frequency (AEHF) system, a US Air Force program.
Some devices that are used or proposed for use as thrusters are: Cold gas thruster; Electrohydrodynamic thruster, using ionized air (only for use in an atmosphere) Electrodeless plasma thruster, electric propulsion using ponderomotive force; Electrostatic ion thruster, using high-voltage electrodes; Hall effect thruster, a type of ion thruster
The U.S. Air Force has stated that the X-37B is testing a Hall-effect thruster system for Aerojet Rocketdyne. [ 36 ] In July 2019, former United States Secretary of the Air Force Heather Wilson explained that when an X-37B was in an elliptic orbit it could, at perigee , use the thin atmosphere to make an orbit change preventing some observers ...
The term ordinary Hall effect can be used to distinguish the effect described in the introduction from a related effect which occurs across a void or hole in a semiconductor or metal plate when current is injected via contacts that lie on the boundary or edge of the void. The charge then flows outside the void, within the metal or semiconductor ...
