摘要
多重库仑散射（MCS）是带电粒子穿过物质时发生的已知现象。MuScat 实验中对低 物质中穿行 μ 子的测量表明，理论模型与模拟代码（如 GEANT4 (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）能量吸收体的 μ 子束流的冷却，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。吸收体材料中发生的能量损失与 MCS 是竞争效应，会改变冷却通道的性能。因此需要 MCS 测量以验证用于预测未来加速器设施冷却性能的模拟。我们报告在 MICE 装置中使用 LiH 吸收体与动量范围 160 至 245 MeV/c 的 μ 子进行的 MCS 测量。测得的 RMS 散射宽度比粒子数据组提出的近似公式预测值小约 9%。172、200 和 240 MeV/c 的数据与 GEANT4 (v9.6) 默认散射模型比较。这些测量显示在该入射 μ 子动量范围内与此较新 GEANT4 (v9.6) 版本一致。
