摘要
文中较详细地介绍了超导磁体用金属液氦广口杜瓦的结构、制作工艺、绝热计算。该杜瓦外径Φ40 0 ,总高 2 5 0 0 ,内胆Φ 3 0 5 ,深 1 80 0 ;绝热方式采用多屏多层超级绝热结构 ,液氦日蒸发量 7.5升。
In this paper, the structure, the technics of the making and the adiabatic estimate are described. The technical data of the dewar are as follows. Outside diameter Φ400mm, total height 2500mm, inside diameter Φ305mm, depth 1800mm, evaporation capacity 7.5L/d.
