Internal plasma potential measurements of a Hall thruster using xenon and krypton propellant Phys. Plasmas 13, 093502 (2006);

The plasma flow in a Hall thruster is analyzed at the limit of intense full ionization. Momentum and energy balance is used to obtain analytical expressions for the current utilization, for the magnitude of the ion backflow current into the anode, and for the location of the ionization region along the channel. Also, axial profiles of flow variables for various input parameters are found by a numerical calculation, that is guided by the analytical expressions.
