Preliminary Experimental Investigation of a Compact High-Efficiency Relativistic Magnetron With Low Guiding Magnetic Field

A compact L-band six-cavity relativistic magnetron with diffraction output is simulated and investigated experimentally. The preliminary experimental investigation is carried out to verify the simulation results. When the applied voltage is ~336 kV and the magnetic field is ~0.21 T, the output microwave power is ~566 MW with the efficiency of about 28%. The radiating frequency is 1.58 GHz which is...
