A relativistic magnetron with a coupling channel as the external resonator

We present the results of the first demonstration experiments on a twofold increase in the output power of a relativistic magnetron with a waveguide coupling channel between opposite cavities of the anode assembly, which contains a specially arranged H-tee and discharge gap. Switching of the gap leads to the formation and extraction of microwave pulses with increased power and short duration from the H-tee.
