Generation of UHF-oscillations in magnetic insulated slow-wave lines

The theory of electromagnetic radiation excitation by an electron Bow is considered for a flat magnetically insulated transmission line with a comb anode. The dispersion relation describing the excitation of electromagnetic oscillations by the Brillouin flow in the slow-wave structure is derived. The numerical analysis of dispersion equation has shown that in the presence of the slow-wave structure, an essential increase in increments of unstable oscillations takes place. The conditions for optimum generation of microwave power are found. Efficiency estimate; are given for the oscillators of the type considered.
