Stabilization of the frequency of relativistic S-band magnetron

Results of experimental research on stabilization of the frequency of relativistic S-band 6-resonator magnetron powered by linear induction accelerator (U~300 κB, I~2.5 kA, τ ≈150 ns) are presented. The frequency of the microwaves was stabilized using a transparent cathode with limited electron emission surface, as well as applying single and double ring straps of the resonators anode block.
