PSI的MEG光谱仪
The MEG Spectrometer at PSI
摘要：
MEG实验是为了寻找轻子味破坏过程$μ\to e^+γ$ \cite{mori-1999,meg2007-baldini}而设计的。这种搜索需要一个高强度的μ子束停止在一个薄的目标与组合事件的背景兼容的最大速率。用高分辨率快速液体氙量热计和由超轻漂移室（DCH）阵列组成的动量测量和双层计时计数器（TC）测量$e^+$时间的光谱仪对事件进行了分析。介绍了该谱仪的设计参数和2008年物理运行期间的性能。
英文摘要：
The MEG experiment is designed to search the Lepton Flavor Violating process $μ\to e^+γ$ \cite{mori-1999,meg2007-baldini}. This search requires a high intensity muon beam stopping in a thin target with the maximum rate compatible with the background from combinatorial events. The events are analyzed by a high resolution and fast liquid xenon calorimeter and by a spectrometer composed by an array of ultra-light drift chambers (DCH) for momentum measurement and a double layered timing counter (TC) for measuring the $e^+$ time. The design parameters and performance of the spectrometer during the 2008 physics run are described.
