在STFC卢瑟福阿普尔顿实验室建立了μ子电离冷却实验（MICE），以演示通过电离冷却来减小μ子束相空间的原理。在未来的质子衍生中微子工厂或μ子对撞机中，将需要μ子束冷却。电离冷却是通过将光束穿过能量吸收材料（如液态氢），然后使用射频腔重新加速光束来实现的。本文介绍了MICE氢气系统的构建，包括液氢吸收器、相关的低温和气体系统、控制和监测系统以及必要的安全工程。介绍了系统在冷却、液化和稳定运行方面的性能。
The Muon Ionization Cooling Experiment (MICE) has been built at the STFC Rutherford Appleton Laboratory to demonstrate the principle of muon beam phase-space reduction via ionization cooling. Muon beam cooling will be required at a future proton-derived neutrino factory or muon collider. Ionization cooling is achieved by passing the beam through an energy-absorbing material, such as liquid hydrogen, and then re-accelerating the beam using RF cavities. This paper describes the hydrogen system constructed for MICE including: the liquid-hydrogen absorber, its associated cryogenic and gas systems, the control and monitoring system, and the necessary safety engineering. The performance of the system in cool-down, liquefaction, and stable operation is also presented.
