Webb15 apr. 2024 · Abstract The long-term experience in controlling the electric field distribution in the discharge gaps of plasma accelerators and thrusters with closed electron drift and the key ideas determining the concepts of these devices and tendencies of their development are analyzed. Webb23 dec. 2014 · An alternative Hall thruster architecture that shifts the ionization and acceleration regions outside the plasma chamber is demonstrated. This unconventional design is here termed a “wall-less Hall thruster,” as the bulk of the magnetized discharge is no longer limited by solid boundaries. A 200 W prototype with permanent magnets has …

Webb1 sep. 2024 · The precessing electrons in this magnetic field follow a closed drift path, giving rise to one of the names for this technique. The flow of the drifting electrons, which is perpendicular to both the applied magnetic field and the current flow in the plasma, is due to the Hall effect, the source of the other name for this type of thruster.

WebbA 2D dual pendulum thrust stand was developed to measure thrust vector of a Hall thruster without thermal effect. A thruster is mounted on a pendulum and gap sensors are mounted on the other. By measuring thrust from the displacement between two pendulums, a thermal drift effect is canceled out.
