Description

CHARM, Cosmic High Altitude Radiation Monitor, is an observatory whose target is the study of cosmic rays. This is actually under construction stage and it consists in a Water Cherenkov Detectors (WCD) array located in Puebla México, at 18.591N and 97.1876W, it is 4300 meters over sea level. Each WCD container is covered inside with a high UV reflectivity material called Tyvek (inner walls) and it is filled with 12000 liters of pure water. The WCD has a sensitive area of 10 m² and the Photomultiplier inside (PMT) is an EMI 9530A (PMT), wich it has the adquisition electronic asociated too. The observatory is designed to study high-energy cosmic rays between 1 PeV – 1 EeV range. This work presents the actual status, the temporal structure signals (peak amplitude and integrated charge) and the stability of the Water Cherenkov Detectors. This study is performed using secondary particles from the background.
