多重库仑散射（MCS）是当带电粒子穿过材料时发生的公知现象。在麝香实验中对穿越低Z材料的μ子的测量表明，理论模型和模拟代码（如GEANT 4（v7.0））高估了散射。μ子电离冷却实验（MICE）测量了穿过液氢或氢化锂（LiH）能量吸收剂的μ子束的冷却，作为开发μ子加速器设施（如中微子工厂或μ子对撞机）计划的一部分。发生在吸收材料中的能量损失和MCS是改变冷却通道的性能的竞争效应。因此，需要测量MCS，以验证用于预测未来加速器设施的冷却性能的模拟。我们报告的测量在MICE装置的MCS使用LiH吸收剂和μ子的动量范围内160至245 MeV/c。实测的均方根散射宽度比粒子数据组提出的近似公式预测的均方根散射宽度小约9%。在172，200和240 MeV/c的数据进行比较GEANT 4（v9.6）默认散射模型。这些测量结果与最近的GEANT 4（v9.6）版本在入射μ子动量范围内的一致性。
Multiple Coulomb Scattering (MCS) is a well known phenomenon occurring when charged particles traverse materials. Measurements of muons traversing low $Z$ materials made in the MuScat experiment showed that theoretical models and simulation codes, such as GEANT4 (v7.0), over-estimated the scattering. The Muon Ionization Cooling Experiment (MICE) measured the cooling of a muon beam traversing a liquid hydrogen or lithium hydride (LiH) energy absorber as part of a programme to develop muon accelerator facilities, such as a Neutrino Factory or a Muon Collider. The energy loss and MCS that occur in the absorber material are competing effects that alter the performance of the cooling channel. Therefore measurements of MCS are required in order to validate the simulations used to predict the cooling performance in future accelerator facilities. We report measurements made in the MICE apparatus of MCS using a LiH absorber and muons within the momentum range 160 to 245 MeV/c. The measured RMS scattering width is about 9% smaller than that predicted by the approximate formula proposed by the Particle Data Group. Data at 172, 200 and 240 MeV/c are compared to the GEANT4 (v9.6) default scattering model. These measurements show agreement with this more recent GEANT4 (v9.6) version over the range of incident muon momenta.
