Diseño e implementación de una estación autónoma de monitoreo de rayos cósmicos y variables ambientales

Abstract

Design of an autonomous cosmic ray monitoring station is composed by a water Cherenkov detector which works with a photomultiplier tube XP1805 and a polarization circuit called Base Auger. The acquisition system is using Red Pitaya board that works with 2 digital analogue channels of 125 MSPS and 14-bit resolution, algorithms are implemented in VHDL and C language for the extraction of the rate data and the digitalization of the events caused by the particles from extensive air shower. In addition, information about ambient temperature, atmospheric pressure and relative humidity is obtained through sensors with I2C interface. The synchronization of the collected information is done by a GPS with UART interface. Power supply is obtained through a photovoltaic system designed with the IEEE standard.
