摘　　要：为了使漂移管加速结构运行更加稳定,传输功率可更好地馈入质子直线加速器中,本文对漂移管加速结构的波导窗进行设计与研究。利用微波仿真软件CST对波导窗的结构进行计算,并通过改善匹配结构对射频参数进行分析及优化。通过仿真结果计算频率带宽、电场分布及功率损耗。最终对波导窗进行热分析,通过公式计算所需冷却水的流量。结果表明,该波导窗可应用于325 MHz加速结构中。In order to make sure that the drift tube linac could work more stable and the transmission power could be fed into the linac better,the waveguide window of accelerating structure was designed and studied in this paper.The structure of waveguide window was calculated by CST,and the RF parameters were analyzed and optimized by improving the matching structure.Then the frequency bandwidth,electric field distribution and power loss were calculated by the simulation result.Besides,the thermal analysis of the RF window was carried out,and the flow rate of the cooling water was calculated by the formula.The result shows that the waveguide window can be applied to the 325 MHz acceleration structure.
