2007年，在卢瑟福阿普尔顿实验室（RAL）进行了一项证明介子电离冷却光束的国际实验。该实验包括研究II冷却通道[1]的一个单元，以及用于识别单个μ子并测量其初始和最终6D相空间参数的上游和下游探测器，精度为0.1%。束流线和冷却通道的磁性设计已经完成，部分正在施工中。实验将描述，包括冷却通道硬件设计，制造状况和运行计划。实验的第一阶段将准备束流线并提供探测器系统，包括飞行时间、切伦科夫、闪烁光纤跟踪器及其光谱仪螺线管和电磁量热计。第二阶段系统将增加冷却通道组件，包括嵌入超导焦点线圈螺线管中的液氢吸收器，201-MHz正常导电射频腔及其周围的耦合线圈螺线管。会展合作计划的目标是在2010年完成实验；讨论了这方面的进展。
An international experiment to demonstrate muon ionization cooling is scheduled for beam at Rutherford Appleton Laboratory (RAL) in 2007. The experiment comprises one cell of the Study II cooling channel [1], along with upstream and downstream detectors to identify individual muons and measure their initial and final 6D phase-space parameters to a precision of 0.1%. Magnetic design of the beam line and cooling channel are complete and portions are under construction. The experiment will be described, including cooling channel hardware designs, fabrication status, and running plans. Phase 1 of the experiment will prepare the beam line and provide detector systems, including time-of-flight,Cherenkov, scintillating-fiber trackers and their spectrometer solenoids, and an electromagnetic calorimeter. The Phase 2 system will add the cooling channel components, including liquid-hydrogen absorbers embedded in superconducting Focus Coil solenoids, 201-MHz normal- conducting RF cavities, and their surrounding Coupling Coil solenoids. The MICE Collaboration goal is to complete the experiment by 2010; progress toward this is discussed.
