摘　　要：高频结构的设计是磁绝缘线振荡器(MAGNETICALLYINSULATEDLINEOSCILLATOR,MILO)实验成败的关键。本文利用电磁场程序研究了L波段硬管MILO的冷腔设计,对其本征模、品质因数、传输增益等冷腔的重要参数进行了计算和讨论,验证了L波段硬管MILO高频电磁结构的合理设计,并通过品质因数的计算对选用不同材料对器件的影响进行了讨论。The design of high frequency structure of Magnetically Insulated Line Oscillator（MILO） is important. The cooling cavity design of a L-band MILO is studied by Partical in cell （PIC） method. Some important parameters are computed and discussed. The results indicate that the high frequency structure of the hard-tube L-band MILO is perfect： the choke vanes could hold back leakage of the microwave toward input port. The main slow-wave structure（SWS） vanes could realize efficient energy transition between microwave and beam, The extractor vane is benefit to efficient output of the microwave. Influence of different materials is discussed by calculating quality-factor.
