摘要
中国工程物理研究院太赫兹自由电子激光装置(CTFEL)的直线加速器由两个4-cell超导加速腔构成,每个加速腔的激励由1套基于感应输出管(IOT)放大器的L波段微波功率源(25kW)提供。本文介绍了微波功率源的基本原理、组成结构和调试过程,以及微波功率源在功率耦合器老炼平台和超导直线加速器上的一些实验结果。微波功率源安装调试后工作稳定,两套微波功率源的主要参数均达到设计要求。超导直线加速器的幅值稳定度和相位稳定度分别为0.04%和0.08°,优于设计指标。
The linear accelerator of the China Academy of Engineering Physics THz Free-electron Laser Facility(CTFEL)consists of two 4-cell superconducting accelerating cavities.The excitation of each accelerating cavity is provided by a set of L-band microwave power source(25 kW)based on an inductive output tube(IOT)amplifier.The basic principle,composition structure and debugging process of the microwave power sources were mainly presented in this paper.And some experimental results of the microwave power sources applying on the power coupler conditioning platform and superconducting linear accelerator were also introduced.The microwave power sources work stably after installation and commissioning,and the main parameters of the two sets of microwave power sources meet the design requirements.The amplitude stability and phase stability of the superconducting linear accelerator reach 0.04%and 0.08°,respectively,which are better than the design targets.
