Popis: The cathode-less microwave discharge ion engine generates plasmas in an ion source and a neutralizer in the method of the collision ionization by electron impact ionization, in which thermal electrons are energized by microwave electronic field without emanating from a cathode. The plasma generation mechanism on the microwave discharge ion source was modeled and formulated based on the global 0-dimensional Brophy’s models conserving particles and energy into the discharge and out of the plasma in the form of charged particles to the walls, beam and plasma radiation. In addition, the ion current of the wall loss in the ion source was measured in the laboratory so that the total amount of the ion production current and the ratio of the ion current contributing to the ion beam are determined.
