为冷却粒子加速器和分离器的超导装置,建造了一个工业规模的HeⅡ制冷机,在1.8K下运行,它具有低的比能耗(对于370瓦的有效制冷量,能耗为436千瓦)。本文叙述了这台制冷机的性能、流程、控制系统和重要组件,并将该设备和以前建造的类似设备作了比较。 To cool the superconducting unit of the particle accelerator and separator, an industrial-scale He II refrigerator was built and operated at 1.8 K with a low specific energy consumption (an energy consumption of 436 kW for an effective cooling capacity of 370 W) . This article describes the performance, flow, control system, and key components of this refrigerator and compares it with similar equipment built previously.
