针对两个预聚束腔工作在回旋频率不同谐波的情况，发展了多腔陀螺器件的理论。结果表明，当第一腔工作于基波，第二腔工作于二次谐波时，电子束流中的谐波含量和第三输出腔的工作效率均高于两个第一腔工作于基波时的结果。在前四个回旋加速器谐波的输出腔的操作效率进行了研究与帐户的电子速度扩展，单和双谐波预聚束的情况下。所获得的结果允许一个估计多腔gyrodevices在回旋谐波的操作效率和电子速度扩散的灵敏度。
The theory of multicavity gyrodevices has been developed for the case when two prebunching cavities may operate at different harmonics of cyclotron frequency. It is shown that when the first cavity operates at the fundamental and the second cavity at the second harmonic, the harmonic content in an electron beam current and the efficiency of operation in the third, output cavity are higher than these when two first cavities operate at the fundamental. The efficiency of operation of the output cavity at the first four cyclotron harmonics was studied with the account for electron velocity spread for both, single‐ and two‐harmonic prebunching cases. The results obtained permit one to estimate the efficiency of operation of multicavity gyrodevices at cyclotron harmonics and its sensitivity to electron velocity spread.
