Design and test of a new MITL for the Yang accelerator

摘要: 介绍了阳加速器新磁绝缘传输线(MITL)的物理设计及实验检验。在缩短MITL整体长度及绝缘环宽度的同时，将原结构改成以共顶点同轴圆锥段为主体的新结构，使阴极表面、绝缘环及三相点满足电场设计要求，最小磁绝缘电流较原结构有所降低，将结构电感从原来的70.9 nH减小到31.7 nH。利用短路实验及丝阵内爆实验对新MITL进行了检验，结果表明新MITL的性能指标有所提高。Abstract: In this paper the physical design and test of a new MITL for the Yang accelerator have been introduced. With reducing the total length of the MITL and width of the insulator, the common-vertex-coaxial-circular-cones-like MITL has been employed to displace the old one, resulting in the decrease of structural inductance from 70.9 nH of the old to 31.7 nH of the new, and electrical stress criterion for some special locations has also been satisfied by reiteration and modification, and minimum magnetic current has been kept below that of the old. The tests both with short load and wire array load have shown that the performance of the new MITL was improved.
