本文研究了30 GHz同轴反射镜相对论衍射发生器。高频系统是一个圆盘加载的圆柱形过模慢波结构。在慢波结构的上游放置同轴反射器，以减少二极管端部的能量泄漏，提高输出功率。该反射器的中心频率为30 GHz。对该装置进行了仿真和实验研究。测得的微波功率超过300 MW，脉宽约为20 ns。通过在器件中增加反射器可以提高微波输出功率。
This paper studies a 30-GHz relativistic diffraction generator with a coaxial reflector. The high frequency system is a disk-loaded cylindrical overmoded slow-wave structure. In order to decrease the energy leaking out from the diode end and increase output power, a coaxial reflector is placed upstream at the slow-wave structure. The reflector is designed with a center frequency of 30 GHz. Simulations and experiments of the device have been carried out. The measured microwave power is over 300 MW, and the pulse duration is about 20 ns. The microwave output power can be enhanced by adding a reflector to the devices.
