High−power microwave radiation has been observed from the interaction of an intense relativistic electron beam and a cavity structure. The efficiency of conversion of electron kinetic energy into microwave radiation was about 20% with a total radiated power of order 500 MW. The mechanism responsible for the efficiency production of microwaves is based on a simple physical model.
