Fabrication and performance test of persistent current switch for superconducting magnet
초전도 마그네트용 영구전류스위치의 제작 및 성능 평가
Abstract
In order to design thermally trigger controlled persistent current switch (PCS) for superconducting magnet system, it is very important to know information of applied adiabatic method and condition to get designed resistance and characteristics In this paper, we used cotton-gummed tape as thermal insulator and derived experimentally averaged thermal conductivity of it around 10K on the assumption that adiabatic structure of PCS is shape of pipe. The result value is about 0.29 W/mK and it is verified reasonable value by computer simulation and experiment of test PCS. Test PCS was designed and manufactured different dimensions. The experimental results of test PCS were in good agreement with the calculated results.
