欧洲核子研究中心的大型强子对撞机(LHC)是世界上最大的科学仪器。1600个“高场”超导磁体组成了周长23公里的加速器环,这是迄今为止超流氦(He II)的最大应用。本章描述了大型强子对撞机磁体低温恒温器的设计演变,重点介绍了He II冷却系统、保温系统和结构支撑。并对低温恒温器的样机试验、批量生产、安装调试等进行了讨论。许多图形和表格说明了低温恒温器和目前的性能结果。
The Large Hadron Collider (LHC) at CERN is the world’s largest scientific instrument. The 1600 “high-field” superconducting magnets that make up the 23 km circumference accelerator ring represent the largest use of superfluid helium (He II) to date. This chapter describes the design evolution of the LHC magnet cryostats with particular emphasis on the He II cooling system, thermal insulation system and structural supports. Prototype testing, series production, installation and commissioning of these cryostats is also discussed. Numerous figures and tables illustrate the cryostat and present performance results.
