  12. 12. Summary and Outlook Low-energy electrons give values for the reduced chi-squared much higher than high-energy muons, even by increasing the thickness of the absorbent or the material, being possible as a consequence to distinguish muons and electrons below 500 MeV. Protons could be identified for the same energy regime, by the measurement of velocity which is always smaller than the one for muons and electrons. By increasing the number of active planes it can be possible to cut low-energy charged particles up to the desired level. In general, protons, muons and electrons shows clusters at different zones on the beta-chi-squared plots, however an important overlapping is also present. Next steps in this analysis will be to perform a full simulation under Geant4 (SETA) which will allows one to get more realistic results. Once this analysis on velocity and chi-squared can be correlated with the arrival time, azimuthal and zenital angles, distance to the core of the shower, etc, the discrimination between particles in case of ambiguity will be possible Teresa Kurtukian Nieto, CENBG 2nd Workshop TRASGO Project February 5th 2010 12
