Abstract Several equations of the electron-wave synchronous interaction in gyrotron oscillator are-derived, in which the effects of the guiding center drift and the phase of the RF field profile are considered. The electron efficiency is calculated for the second harmonic operation of the TE021 mode for a double-cavity gyrotron model, in which the RF field profile and operation parameters of the gyrotron are adjusted. It is shown that the efficiency of 53% can be attained for α=1.5. The characteristic of the double-cavity structure is discussed. The bunching processes of the single and double cavities are compared. The effect of the guiding center drift and the Phase of the RF field profile on the electron-wave interaction in analysed.
