摘要：In the last months of 2009, during the commissioning of the Resistive Plate Chambers (RPC) Time Of Flight (TOF) wall for the High-Acceptance DiElectron Spectrometer (HADES) at the GSI (Darmstadt, Germany), more than 500 millions of cosmic ray events were recorded with a time resolution better than 100ps, a reconstructed position resolution of the order of a few cm2 and with granularities ranging from 25cm2 to 270cm2. Events were recorded with pairs of detectors of 1.25m2, stacked horizontally and separated by a distance of 35cm. We have analysed the performances that such setup offers for the study of cosmic rays and the microstructure of the cosmic ray-induced Extended Air Showers (EAS) fronts.
