Stabilization of the Frequency of Relativistic S-Band Magnetron With Radial Output

The results of experimental research on the stabilization and tuning of the frequency of a relativistic S-band six-resonator magnetron powered by a linear induction accelerator ( U ≈ 300 κB, I ≈ 2.5 kA, and τ ≈ 150 ns) are presented. The frequency of the microwaves was stabilized using a partial reflection of the generated microwave power P ≈ 300 MW from the output of the magnetron and a proper adjustment of the phase of the reflected microwaves.
