Gyrokinetic formula and experimental examination of the electron-beam misalignment effect on the efficiency of a cylindrical-cavity gyrotron oscillator.
By making use of the gyrokinetics of free-electron masers, the efficiency formula of a cylindrical-cavity gyrotron oscillator is presented, where the misalignment of the electron-beam axis to the cavity axis has been taken into account. Comparison with a recent experimental report [Int. J. Infrared and Millimeter Waves 19, 1303 (1998)] is made, which confirms the creditability of the gyrokinetic theory.
