Plasma-filled dielectric Cherenkov maser
Abstract
Recent experimental results have indicated that the use of a background plasma in high power microwave devices can increase the space charge limiting current in the device and also increase the microwave power output. Here, the effect of a background plasma on a dielectric Cherenkov maser is examined by solving the linearized, beam-plasma, dielectric lined waveguide dispersion relation. A discussion of the output frequency and growth rate dependence of the device on the background plasma density and dielectric lined waveguide parameters will be presented.
