本文综述了近年来相对论返波管高功率微波产生超辐射区的研究进展。从理论和模拟两方面论证了产生峰值功率大大超过驱动电子束功率的微波脉冲的基本可能性。在实验中，波束到微波功率转换因子的1.5在Ka波段和高达1.8在X波段实现。高效率的Ka波段产生在回旋共振以下的低B场（2 T）。使用直流螺线管，SR脉冲在1000-3500 Hz的脉冲重复频率下以批量模式产生。
This paper presents a review of recent studies of superradiant (SR) regime of high-power microwave generation of relativistic backward-wave tubes. The fundamental possibility of producing microwave pulses with peak power substantially exceeding the driving electron beam power was demonstrated in theory and simulation. In experiments, beam-to-microwaves power conversion factors of 1.5 in the Ka band and up to 1.8 in the X band were achieved. High-efficiency Ka band generation was obtained at a low B field (2 T) below the cyclotron resonance. With the use of a dc solenoid, SR pulses were generated in a batch mode at a pulse repetition frequency of 1000-3500 Hz.
