摘要:

Muon望远镜是哥伦比亚的一个火山成像实验。它由闪烁体跟踪系统和用于粒子沉积能量测量的水切伦科夫探测器组成。MuTe在温度梯度高达$10$ $^{\circ}$ C的高海拔环境中自主运行。在这项工作中,我们的特点的击穿电压,增益和噪声的望远镜硅光电倍增器的温度变化跨越$0$ $40$ $^{\circ}$ C。我们证明了MuTe hodoscope的鉴别阈值必须高于5 pe,以避免由于SiPM暗计数、串扰和后脉冲而造成的污染。我们还评估了穆特计数率取决于昼夜温度变化。

英文摘要:

The Muon Telescope is a muography experiment for imaging volcanoes in Colombia. It consists of a scintillator tracking system and a water Cherenkov detector used for particle deposited energy measurement. The MuTe operates autonomously in high altitude environments where the temperature gradient reaches up to $10$$^{\circ}$C. In this work, we characterize the breakdown voltage, gain, and noise of the telescope silicon photomultipliers for temperature variations spanning $0$ to $40$$^{\circ}$C. We demonstrated that the discrimination threshold for the MuTe hodoscope must be above 5 pe to avoid contamination due to the SiPM dark count, crosstalk, and afterpulsing. We also assess the MuTe counting rate depending on day-night temperature variations.
