WebHall thrusters are currently one of the most advanced and efficient types of electrostatic propulsion devices for spacecraft with an efficiency of about 50% [53].In particular, this configuration is beneficial because the acceleration takes place in a quasi-neutral plasma and thus is not limited by space-charge effects. Web13 dec. 2024 · If the beam ions stay ionized, all following ions are repelled by their charge, reducing their speed and thrust. The highest thrust can be reached if the ion beam is perfectly focused. If it's charged, the ions will repel each other, broadening the beam. cindy farrant south australia

Ion and hall thrusters

WebAt other locations in ion and Hall thrusters, such as in some cathode and accelerator structures, a situation may exist where two plasmas are in contact but at different potentials, and ion and electron currents flow between the plasmas in opposite directions. This situation is called a double sheath, or double layer, and is illustrated in Fig ... WebHowever, the mechanism for transferring the thrust from the ion motion to the thruster body, and thereby the spacecraft, is different for ion thrusters and Hall thrusters. In ion thrusters, ions are produced by a plasma source and accelerated electrostaticly by the field applied between two (or more) grids, as illustrated in Fig. 2-1.
