Abstract: The use of a background plasma in a dielectric Cherenkov maser can effectively increase the efficiency and the microwave power output of the device. Here, the effect of the longitudinal uniform magnetic field on the wave-beam interaction of the plasma dielectric Cherenkov maser is examined by solving the beam-plasma, dielectric lined waveguide dispersion equation. And the effects of the longitudinal magnetic field, plasma density and dielectric parameters on the linear spatial growth rate and the energy ratio are presented. -
