45特斯拉混合磁体系统将由14特斯拉超导外露磁体和31特斯拉水冷插入物组成。该磁体计划于1995年初在国家高磁场实验室运行。其目的是为材料研究界提供最高的直流磁场。本文讨论了超导磁体低温系统的总体设计。该系统的独特功能包括作为磁体冷却剂的静态1.8K加压氦气II，以及在故障条件下用于负载转移的制冷结构支持系统。该系统将由两个相连的低温恒温器组成。该磁体包含在一个冷冻器内，该低温恒温器具有616 mm的透明热孔，并且设计为没有系统接口，因此最大限度地减少了对磁体用户的干扰。第二个电源低温恒温器提供与制冷系统和磁体电源的连接。磁体和供应式低温恒温器通过水平服务管道部分相互连接。本文讨论的问题包括冷却和稳态运行时磁体系统的设计和热分析，以及低温系统的总体设计。
The 45 Tesla hybrid magnet system will consist of a 14 Tesla superconducting outsert magnet and a 31 Tesla water cooled insert. The magnet is planned for operation in early 1995 at the National High Magnetic Field Laboratory. Its purpose is to provide the highest DC magnetic fields for the materials research community. The present paper discusses the overall design of the cryogenic system for the superconducting magnet. Unique features of this system include static 1.8 K pressurized He II as a coolant for the magnet and a refrigerated structural support system for load transfer during fault conditions. The system will consist of two connected cryostats. The magnet is contained within one cryostat which has a clear warm bore of 616 mm and is designed to be free of system interfaces and therefore minimize interference with the magnet user. A second supply cryostat provides the connections to the refrigeration system and magnet power supply. The magnet and supply cryostats are connected to each other through a horizontal services duct section. Issues to be discussed in the present paper include design and thermal analysis of the magnet system during cooldown and in steady state operation and overall cryogenic system design.
