A numerical computational method for the calculation of the bulk characteristics of an electron beam sustainer discharge, in the presence of a flowing or stationary medium, is presented. The sustainer electric field is taken perpendicular to the flow direction, as it is commonly found in a large class of high-energy electrically pumped lasers. A detailed discussion of the underlining assumptions of the computational method is given. Typical results of the numerical calculations are presented in detail.

An electron impact facility based on a ribbon filament cathode, simple diode gun, and thin aluminium foil window is described. The facility is designed for the study of gas phase electron impact phenomena at pressures up to one atmosphere in a variety of gases. Of particular interest is the simple design of the electron gun for generating electron beams having energies up to 100 keV and currents up to 5 mA. The beam is magnetically collimated and directed through a thin aluminium foil which is used as the vacuum-gas interface to an impact chamber. Maximum power delivered to the impact region depends on the thickness of the foil window. Using an 8.4 pm thick aluminium foil. approximately 150W can be delivered to the impact chamber. Thermal heating of the foil by the electron beam is t h e limiting factor restricting higher effective power transmission.
