MIDAS: A particle identification tool for the TRAGALDABAS Cosmic Ray telescope.
2019 September 27
Tragaldabas is a timing-RPC-based Cosmic Ray telescope, a member of the Trasgo family. It is intended for analyzing different aspects of Cosmic Ray Physics. The detector, with a footprint of 1.8 m2, offers tracking capability with an angular resolution of about 0.01 sr and time resolution close to 0.3 ns. This telescope is taking data regularly since April 2015. By means of simulation, a powerful tool for Electron/Muon track identification, MIDAS (Multisampling IDentificAtion Software), has been developed over the Tragaldabas detector. The method is based on a systematic study of several observables that are associated with track reconstruction; such as, the Chi-square of the track-fitting, the number of cells fired over all the planes of the detector or the normalized track length, among others. In the case of electrons, this method is able to give an estimate of its energy. Its accuracy is close to 99% for Electron-Muon separation using simulated data.
