The superior operation of a S-band relativistic magnetron powered by a Linear Induction Accelerator with ≤400 kV, ≤4 kA, and ∼150 ns output pulses was revealed when the magnetron was coupled with a resonance load and a part of the generated microwave power stored in the resonator was reflected back to the magnetron. It is shown that, under optimal conditions, the efficiency of the magnetron operation increases by ∼40% and the generated microwave power reaches the power of the electron beam.
