MICROWAVE GENERATION BY MEANS OF INTERACTION WITH ANISOTROPIC MEDIA.
Abstract
The equations pertinent to the interaction of an electron beam with a stationary plasma in the second-order perturbation are presented and solved in a dimensionless form suitable for computer calculation. The perturbation is the initial modulation on the electron beam as it enters the plasma and the second-order solution yields a second harmonic wave and a d-c correction to the zeroth-order state. The design of a beam-plasma experimental device is presented and the design of elliptic cavity couplers is discussed. The beam-plasma amplifier will utilize the double-ended PIG discharge and the electron beam is produced by a microperveance one Pierce type gun designed to operate around 1 kilovolt. The dispersion equation for a beam-plasma interaction in which the plasma is spatially inhomogeneous is developed and solved and gain equation are developed for both velocity modulated and current modulated beams interacting with the plasma. Gain vs. electronic wavelengths are shown graphically including the effect of collisions. The nonlinear beam-plasma interaction equations are discussed including spatial variations of magnetic field and plasma particle density. (Author)
