行波谐振环和陶瓷窗高功率老炼
Travelling wave resonant-ring for RF window high power test
-
摘要: 为了老炼国家同步辐射实验室200 MeV直线加速器新陶瓷窗，制作了一个功率增益4.5，最高峰值功率60 MW的波导行波谐振环。对谐振环的工作原理和技术参数进行了简单介绍。对陶瓷窗功率老炼的步骤和应注意的技术细节进行了较详细的分析，提出了克服电子倍增效应的一些方法。陶瓷窗老炼峰值功率为30 MW，平均功率3.7 kW，脉冲长度2.5μs。Abstract: A travelling wave resonant-ring was constructed for RF window high power test of NSRL 200 MeV Linac. The principle of the resonant-ring was described. A power gain of 4.5 and a peak power of 60 MW were achieved in the ring. The power test method and procedure were given out, and the electron multiple effect was discussed. The RF window passed test under the conditions of a peak power of 30 MW, an average power of 3.7 kW and a pulse length of 2.5μs．
