| Abstract: | general equation of electron-wave synchronous interaction is obtained in gyrotron oscillator, in which the effects of guiding center drift and phase of RF field profile is considered.The interaction efficiency is calculated for the second harmonic operation of single TE_(021) mode for a double cavity gyrotron oscillator model,in which the RF field profile and operating parameters of the gyrotron oscillator are regulated in order to get optimum efficiency.It is shown that the efficiency of 53 percent can be obtained for a =1.5.The characteristic of the double cavity configuration is discussed.The bunching processes of the double cavities are compared with that of single cavity.The effects of guiding center drift and RF field profile phase on the beam-wave interaction are analysed. |
