Calibration of a large water-Cherenkov detector at the Sierra Negra site of LAGO (original) (raw)

The Latin American Giant Observatory (LAGO) employs water Cherenkov detectors (WCD) to detect gamma ray bursts (GRBs) in collaboration with key sites in South and Central America, including Mexico. This research details the calibration of a WCD at the Sierra Negra site, including characterization of photomultiplier tubes (PMTs) and an analysis of stability over time. Preliminary data indicates stable rates with minimal dispersion, and the effectiveness of a newly implemented data acquisition system is demonstrated through results, including detailed distributions of charge and rise time.
