混合磁体超导线圈低温传输线冷屏的设计与分析

Design and analysis of thermal shield of busline for the superconducting coil in the hybrid magnet

对于低温传输线,冷屏是其重要的结构。文中在低温传输线冷屏结构初步设计的基础上,对冷屏屏体材料进行比选,计算分析了低温传输线在80K温区的漏热量,并采用Solidworks软件,对不同厚度的低温传输线冷屏的温度分布进行模拟分析,完成冷屏的工程设计。

The thermal shield is one of the most important components of the busline. This paper compared the materials for the thermal shield, calculated and analysed the heat loss for the busline on the basis of preliminary design. Simulation and analysis on the temperature distrubution of the thermal shield with different thickness with the help of Soliworks were done.
