正在卢瑟福阿普尔顿实验室（RAL）建设的国际μ子电离冷却实验（MICE）将展示电离冷却的原理，作为减少μ子束所占相空间体积的技术。中微子工厂和μ子对撞机需要电离冷却通道。MICE将详细评估可行性研究2冷却通道的单个网格单元的性能。MICE μ子束已在RAL的ISIS同步加速器上建造，在MICE步骤I中，它已使用MICE束仪器系统进行了表征。本文介绍了MICE μ子束和束线装置。的μ介子率作为由MICE目标浸入ISIS质子束产生的束损失的函数。对于来自我们目标下游的ISIS束流损失监测器的1 V信号，我们获得了30 KHz的瞬时μ介子速率，束中的π介子污染可以忽略不计。
The international Muon Ionization Cooling Experiment (MICE), which is under construction at the Rutherford Appleton Laboratory (RAL), will demonstrate the principle of ionization cooling as a technique for the reduction of the phase-space volume occupied by a muon beam. Ionization cooling channels are required for the Neutrino Factory and the Muon Collider. MICE will evaluate in detail the performance of a single lattice cell of the Feasibility Study 2 cooling channel. The MICE Muon Beam has been constructed at the ISIS synchrotron at RAL, and in MICE Step I, it has been characterized using the MICE beam-instrumentation system. In this paper, the MICE Muon Beam and beam-line instrumentation are described. The muon rate is presented as a function of the beam loss generated by the MICE target dipping into the ISIS proton beam. For a 1 V signal from the ISIS beam-loss monitors downstream of our target we obtain a 30 KHz instantaneous muon rate, with a neglible pion contamination in the beam.
