摘要:

AMIGA(Auger Muons and Infill for the Ground Array)是对皮埃尔·俄歇天文台的一次改进。它由更密集的表面探测器阵列和μ子计数器组成,其目标是将探测范围扩展到10^17 eV,并帮助确定质量组成。后者是实现与μ子计数器,因为簇射μ子内容是粒子类型识别的最佳参数之一。在这项工作中,我们提出了一个μ子计数器原型的研究。原型被埋在3米深的地方,以避免来自淋浴电磁组件的信号污染。我们研究了探测器及其相关电子元件埋置前后的性能。通过对穿过计数器的带电粒子的信号分析来执行检测器验证。

英文摘要:

AMIGA (Auger Muons and Infill for the Ground Array) constitutes an enhancement for the Pierre Auger Observatory. It consists of a denser array of surface detectors and muon counters whose objective is both to extend the detection range down to 10^17 eV and to help towards mass composition determination. The latter is to be achieved with muon counters since the shower muon content is one of the best parameter for particle type identification. In this work, we present the study of a muon counter prototype. The prototype was buried 3 m deep in an effort to avoid signal contamination from the shower electromagnetic component. We study the performance of the detector before and after burying it with its associated electronic components. The detector validation is performed from signal analysis of charged particles traversing the counter.
