Abstract

We study the possibility to advance relativistic planar Čerenkov surface-wave oscillators, which are driven by intense sheet electron beams, to the subterahertz frequency range within the framework of the performed simulation. It is shown that the use of two-dimensional periodic slow-wave structures providing the two-dimensional distributed feedback allows one to ensure high coherence of radiation at the subgigawatt power level in oscillators of this kind for transverse sizes equal to hundreds of wavelengths. The design parameters and structural elements are discussed for implementing such high-power oscillators based on the ELMI accelerator complex within the framework of the joint BINP/IAP experiments.

亚赫兹频率范围内具有二维分布式反馈的大功率平面捷伦科夫振荡器的设计与仿真

我们研究了在所进行的模拟框架内，将强片电子束驱动的相对论平面采伦科夫面波振荡器推进到次赫兹频率范围的可能性。结果表明，使用提供二维分布式反馈的二维周期性慢波结构，可以确保此类振荡器在横向尺寸相当于数百个波长的情况下，在亚兆瓦级功率水平上实现高相干性辐射。在 BINP/IAP 联合实验的框架内，讨论了基于 ELMI 加速器综合体的高功率振荡器的设计参数和结构元素。
