Abstract
El proyecto AMIGA (“Auger Muon and Infill for the Ground Array”) es una extensión del Observatorio Pierre Auger y sus objetivos principales son mejorar la discriminación entre partículas primarias de diferente composición química y la detección de lluvias de partículas con un umbral de energía más bajo que el utilizado en el diseño original de Auger. Este trabajo se centra en el detector de muones de AMIGA, más específicamente en el desarrollo de la electrónica de adquisición para los contadores de muones reemplazando el sistema de fotodetección por una nueva tecnología basada en fotomultiplicadores
de silicio (SiPMs). Se presentará la selección del fotodetector y de la electrónica de adquisición. Se
exponen las diversas pruebas de concepto en la que se mostrarán las capacidades del sistema de detección seleccionado y se propondrá una versión de pre-producción de la electrónica. Se presentará el método desarrollado para la calibración tanto de los SiPMs, cómo del detector. Se expondrán las pruebas realizadas en el laboratorio para la caracterización del sistema de conteo propuesto, la instalación de las electrónicas de pre-producción en la estación del detector de superficie Kathy Turner con las respectivas pruebas realizadas y los primeros análisis de datos del detector.
The AMIGA project (“Auger Muon and Infill for the Ground Array") is an extension of the Pierre Auger Observatory and its main objectives are to improve the discrimination between primary particles of different chemical compositions and the detection of cosmic ray showers with a lower energy threshold than the original Auger design. This work is focused on the AMIGA muon detector, more specifically in the development of the acquisition electronics for the muon counters, replacing the current photodetector with a new technology based on silicon photomultipliers (SiPMs). The selection of the photodetector and the acquisition electronics for the AMIGA muon counters will be presented, as well as the different tests in which the capabilities of the selected detection system are shown. A pre-production version of the electronics will be proposed. The method developed for the calibration of the SiPMs and the detector using the designed electronics will be presented. Also the laboratory tests for the characterization of the proposed counting system are be presented, the installation of the pre-production electronics in the surface detector station Kathy Turner, the respective tests performed in the field and the first data analysis of the detector.
