• Resumen

  • We are currently in the process of calibration of a new cosmic ray detector called SciBar Cosmic Ray Telescope (SciCRT) located at the top of the Sierra Negra volcano at 4,600 m.a.s.l., in Eastern Mexico. The SciCRT will work mainly as a Solar Neutron and Muon Telescope, with a high angular resolution (~ 1º), but it will also serve as a gamma ray and hadron shower detector. The mini-SciCR is a prototype of the SciCRT, it uses the same scintillator bars and recording hardware, the size of the mini-SciCR that was opeating at the top of the Sierra Negra volcano from October 2010 to July 2012. Our main aims were to show the appropriate performance of all the detector systems and to develop a technique to separate the flux of soft and hard secondary cosmic rays with the help of a Monte Carlo simulation, our energy range of interest is from 100 MeV to a few GeV. Aditionally we will report results with a modification of the detector setup that helped to confirm he correct identification of the particle species.
