Cathode Effects in Cylindrical Hall Thrusters [PDF]
Journal of Applied Physics, 2008 Stable operation of a cylindrical Hall thruster (CHT) has been achieved using a hot wire cathode, which functions as a controllable electron emission source. It is shown that as the electron emission from the cathode increases with wire heating, the discharge current increases, the plasma plume angle reduces, and the ion energy distribution function ...
