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.
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 ...
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 ...
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.
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
Psyche is the first interplanetary mission to use Hall-effect thrusters, although not the first to use electric thrusters in general. [ 42 ] The SPT-140 (SPT stands for Stationary Plasma Thruster ) is a production line commercial propulsion system [ 3 ] that was invented in the USSR by OKB Fakel and developed by NASA's Glenn Research Center ...
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 ...
