在这项工作中，我们描述了 MuTe 调试过程中的校准和首次测量，MuTe 是一种混合介子望远镜，配有两个子探测器——闪烁体视距仪和水切伦科夫探测器 (WCD)——用于对哥伦比亚火山的内部结构进行成像。测距仪估计撞击前面板和后面板的粒子轨迹，而 WCD 则充当穿过带电粒子的热量计。
MuTe 结合了粒子识别技术，以区分数据中的噪声背景。它过滤 mu 成像的主要噪声源，即大范围空气阵雨 (EAS) 的电磁分量 ($e^{\pm}$) 和散射/上行 μ 介子。 WCD 通过沉积能量识别电子/正电子事件，而使用皮秒飞行时间 (ToF) 系统拒绝散射和后向 μ 子。
在穿过一米长度的沉积能量沉积范围（$144$MeV$$3.3 ns）中发现了 μ 子生成事件。
In this work, we describe the calibration and first measurements in the commissioning of MuTe, a hybrid Muon Telescope with two subdetectors --a scintillator hodoscope and a Water Cherenkov Detector (WCD)-- for imaging the inner structures of Colombian volcanoes. The hodoscope estimates the trajectories of particles impinging on the front and rear panel, while the WCD acts as a calorimeter for the through going charged particle.
MuTe combines particle identification techniques so as to discriminate noise background from data. It filters the primary noise sources for muography, i.e., the EM-component ($e^{\pm}$) of Extensive Air Showers (EAS) and scattered/upward-coming muons. The WCD identifies Electrons/positrons events by their deposited energy identifies, while scattered and backward muons are rejected using a pico-second Time-of-Flight(ToF) system.
Muon generated events were found in the deposited energy deposited range of ($144$MeV$ $ 3.3 ns for traversing one meter length.
