40T混合磁体外超导磁体杜瓦真空系统设计

摘要

Based on the vacuum requirement of the cryostat, the vacuum system for the Cryostat for 40 T hybrid magnet was designed. The vacuum system includes roots pumping sets consisting of two ZJ-70 and 2XZ-15 pumps which can achieved 1 Pa, and turbo-molecular pumping sets consisting of two F250/1500 and 2X-30 pumps which can achieved 0.01 Pa.%根据40 T稳态混合磁体外超导磁体杜瓦对真空的要求,对杜瓦真空系统进行了设计计算,计算结果如下:杜瓦真空系统包括粗抽泵机组和主泵机组,其中粗抽泵机组由两套ZJ-70罗茨泵和2XZ-15直联式旋片真空泵组成,可将杜瓦真空抽至1 Pa；主泵机组由两套F250/1500涡轮分子泵和2X-30旋片式机械泵串联组成,可将杜瓦真空抽至0.01Pa.
