Abstract

The TRASGO project develops high resolution tracking detectors, sensitive to single electrons and muons as well as to bundles of both kinds of particles. Two detectors are now operative and two more stations will start taking data for atmospheric studies soon. Thanks to the identification capability of the detectors, they are well suited to estimate the arrival rates of primary cosmic rays with different energy thresholds. This is validated after performing several simulations and opens new possibilities in the research of cosmic rays from ground-based detectors.

Notes

  1. Namely, we choose four intervals per energy decade centered at the values (in GeV): 1, 1.77, 3.16, 5.62, 10, 17.7… and so on. In each interval the energies generated followed the well known \(E^{-2.7}\) power law.

  2. Although perhaps this is not the most appropriate model for low energy interactions, we decided to use it because we are interested to extrapolate our results to higher energies. It is foreseen to repeat the simulation using other interaction models and parameters.

  3. For the results we are presenting we have chosen a distance of 2 m.
