| 摘 要： | 根据渡越时间效应3维理论研究，设计了一种工作于6.1 GHz的新型径向边加载渡越时间振荡器。为增强电子束在谐振腔中的横向摆动，部分加大了高频结构中金属圆筒端部的宽度，以增大横向电场的的分布区域。3维理论分析表明,该器件的效率可以超过50%。粒子模拟研究表明,该器件在170 kV，18 kA的电子束激励下，平均输出功率达到1.6 GW，束波互作用效率为52.3%。

| Abstract: | A new side-appending radial three-cavity transit time oscillator is proposed based on the 3D single particle theory of transit time effects. For enhancing the transverse swing of the beam in the cavity, some annuluses’ ends are widened, and so the transverse fields can be strengthened. The 3D theory demonstrates that, the oscillator can obtain an efficiency higher than 50%. Numerical simulation indicates that, it can produce an average power of 1.6 GW at 6.1 GHz with the beam-wave interaction efficiency of 52.3%, when excited by a 170 kV, 18 kA radial electron beam. |
