国际μ子电离冷却实验（MICE）将在卢瑟福阿普尔顿实验室的ISIS设施中使用动量在140和240 MeV/c之间的μ子束进行电离冷却的系统研究。MICE中电离冷却的测量依赖于选择穿过实验的纯μ子样品。为了做出这种选择，MICE μ子束被设计为提供污染小于101%的μ子束。为了进行最终的μ子选择，MICE在冷却单元的上游和下游采用了粒子识别（PID）系统。PID系统包括飞行时间的hodoscope，阈值切伦科夫计数器和量热法。在90%C. L.时，测量的π介子污染上限为fπ < 1.4%。包括系统的不确定性。因此，MICE μ子束能够满足电离冷却研究中严格的π介子污染要求。
The international Muon Ionization Cooling Experiment (MICE) will perform a systematic investigation of ionization cooling with muon beams of momentum between 140 and 240 MeV/c at the Rutherford Appleton Laboratory ISIS facility. The measurement of ionization cooling in MICE relies on the selection of a pure sample of muons that traverse the experiment. To make this selection, the MICE Muon Beam is designed to deliver a beam of muons with less than ∼1% contamination. To make the final muon selection, MICE employs a particle-identification (PID) system upstream and downstream of the cooling cell. The PID system includes time-of-flight hodoscopes, threshold-Cherenkov counters and calorimetry. The upper limit for the pion contamination measured in this paper is fπ < 1.4% at 90% C.L., including systematic uncertainties. Therefore, the MICE Muon Beam is able to meet the stringent pion-contamination requirements of the study of ionization cooling.
