Zusammenfassung:Large overmoded coaxial mymargin slow wave structure was adopted to overcome the problems of low power capacity and narrow electron beam channel in V-band. Based on the simulation design of coaxial Cerenkov oscillator, the experimental research was carried out in this letter. The output microwave with power 226 MW, pulse width 18 ns, frequency 63.2 GHz can be measured, corresponding efficiency is 23%. The influence of voltage and magnetic field on the generation of microwave was also studied. The experimental principle is consistent with the simulation design.
