MILLIMETER WAVE COMPONENT DEVELOPMENT (BEAM-PLASMA AMPLIFIER).
Abstract
Experiments are described on a plasma tester which allows radial and axial density profile measurements to be taken. A definite density maximum in the radial profile is shown which was not heretofore observed in previous experiments. The axial profiles show a maximum in the center of the discharge. Data was taken with pressure and magnetic field as parameters. A new Langmuir probe design is discussed in which the probe is shielded from cathode evaporation and sputtering. A theory for the double-hot-cathode PIG discharge is described based on ambipolar diffusion in a magnetic field. The theory indicates density profiles that are in agreement with experiments. Thus it is concluded that the discharges are diffusion controlled. The present status of the 2 mm BPA study vehicle is described. The results of electrical measurements on some of the waveguide components are discussed. (Author)
