大轨道回旋管是一种高次谐波回旋器件，它具有环绕电子束的特性，是传统回旋管的一种很有吸引力的替代方案。在本文中，我们探讨了这种设备的可行性与低电流和低能量的电子束形成的一种新型的电子枪与永磁系统。数值实验结果表明，在回旋频率的四次谐波处激发TE 41模是可能的。模拟预测产生的微波辐射频率为104 GHz，输出功率接近1 kW。
High-harmonic gyro-devices with axis-encircling electron beams known as large orbit gyrotrons (LOG) represent an appealing alternative to the conventional gyrotrons. In this paper we investigate the feasibility of such device operating with low current and low energy electron beams formed by a novel electron gun with a permanent magnet system. The results from the numerical experiments indicate the possibility to excite TE41 mode at fourth harmonic of the cyclotron frequency. Simulations predict generation of microwave radiation with frequency 104 GHz and output power near 1 kW.
