Web4. WORKING AND DESIGN OF HALL THRUSTERS First studies about all thrusters began in the early ’60 independently in the URSS and USA. However, Hall thruster technology was developed to flight status in the former Soviet Union, whereas the US research activities focused on Hall Thruster [4][5]. Two types of modern Hall thrusters WebHall thrusters generate thrust by creating and accelerating ionized gas via an electric field. Confined within a finely shaped magnetic field, electrons gyrorotate within the channel until they ionize a neutral atom. The ionized plasma is then accelerated by the electric field to exhaust velocities of greater than 25,000 m/s. WebDan M. Goebel, PhD, is a Senior Research Scientist in the Advanced Propulsion Technology Group at JPL in Pasadena, California. Since joining JPL in 2003, he has worked on the development of high-efficiency ion thrusters, advanced long life cathodes and grids, and electric-thruster life models for deep space missions. impeachment with sarah paulson
