Ionizing Layers in the Plasma Propulsion Devices
Abstract
In the field of plasma propulsion, there re essentially the following types of devices: 1) Steady state D. C. arc jet accelerators (without applied magnetic field); 2) Hall current D. C. accelerators (with applied axial magnetic field) or quasisteady pulsed Hall current accelerators; 3) Magnetic piston type of accelerators. The efficiencies of these devices range from 20 to 90 percent depending probably in some degree on the methods of measurement. It is essential that the efficiency be optimized, since the larger the losses the larger the size of the radiator that is required to reject the heat. In this paper the author examines the following topics: The radiation and ionization energy losses, the energy losses due to wall bombardment by ions and the ion current, magnetic piston discharge layer, rarefaction type of discharge layer and he finally analyses the equations of the Hall current accelerator.
