Study of atmospheric Showers Simulations, for Low Energies using Trasgos

Abstract:

In this work we present a new proposal to study the primary radiation mass composition at low energies for atmospheric extended showers (EAS), using detectors called Trasgos (TRack and time reconStructinG bOx). There consist on a stack of timing Resistive Plate Chambers (tRPC) with the advantages of high time and space resolution, as well as tracking capabilities. These characteristics allow us to analyze the arrival of the secondary particles and the fine structure of the EAS front. Our simulations consider the lateral distribution of particles near to the core of the EAS, where the electromagnetic to muonic ratio depends more strongly of the effective cross section, i.e. the mass of the primary particle.
