摘要
本文研究了适合于低频段宽带多注速调管的新型微波谐振腔——半波长矩形同轴腔,用三维电磁场计算软件ISFEL3D 计算了矩形同轴腔的高频参数和场分布,并与双间隙耦合圆柱腔进行了分析比较。结果表明,矩形同轴腔体积小,带宽潜力大,可应用于低频段多注速调管。
A kind of rectangular coaxial cavity, which is used for low frequency broadband multiple beam klystron, is studied. The 3D electromagnetic code of ISFEL3D is used to calculate the main parameters and field distribution of rectangular coaxial cavity. The results show that rectangular coaxial cavity has small volume and potential of bandwidth extending. It can be used in low frequency band multiple beam klystrons.
