摘要

我们已经建造了一个切伦科夫脉泽振荡器，设计工作频率为16.9 GHz，固体电子束加速到70千伏，使用一根氧化铝管，安装在铜管上。给出了不同介电负载结构的腔体色散曲线的测量结果。本文还描述了一种有效计算介电衬里与波导壁之间有小间隙的圆柱切伦科夫自由电子器件色散曲线的方法。在任何实际实现中，这样的间隙都是不可避免的，这里得到的结果表明，色散曲线对其厚度非常敏感。

Computational method for the dispersion relation of a pulsed Cerenkov free electron maser system

We have constructed a Cerenkov maser oscillator designed to operate at 16.9 GHz with a solid electron beam accelerated to 70 kV, using an alumina tube, fitted into a copper pipe. The measurements of the dispersion curves for such a cavity of various dielectrically loaded structures are presented. A method for calculating efficiently the dispersion curve of a cylindrical Cerenkov free electron device having a small gap between the dielectric liner and the waveguide wall is also described. In any practical realisation, such a gap cannot be avoided and the results obtained here indicate that the dispersion curve can be very sensitive to its thickness.
