2D Bragg high power microwave source driven by an annular electron beam

Journal article

The first successful cold microwave measurements of a 2D Bragg coaxial mirror were discussed. An important difference between 1D and 2D Bragg structures was demonstrated concerning the dependence of their reflection coefficient on the parameter αlz, where α denotes wave coupling coefficient and lz represents length. The minimum of the transmission was found to be the same for the 2D structures. The possibility of achieving single mode operation was also demonstrated for the Free Electron Masers (FEM) when driven by an oversized electron beam with D/λ∼25, where D denotes diameter of the microwave system used and λ stands for wavelength of radiation.
