Abstract

An integral criterion is suggested, which characterizes the configuration of magnetic field in a thruster with closed electron drift from the standpoint of efficiency of confinement of electrons in the ionization region. For the purpose of investigating the validity of the criterion, a thruster is developed with a new design of magnet system, which enables one to vary the structure of magnetic field in a wide range. The experimental investigation of the effect of magnetic field structure on the efficiency and specific impulse of plasma thruster revealed correlation between the results of application of the criterion and the parameters of efficiency of the thruster.
