Description
The Latin American Giant Observatory (LAGO) is an international network of water-Cherenkov detectors (WCD) set in different sites across Latin America. In México, on the top of the Sierra Negra volcano at 4530 m a.s.l., LAGO has completed its first instrumented detector of an array, consisting of a cylindrical WCD with 7.3 m in diameter and 1 m of height, with a total detection area of $40$ m$^2$ and sectioned in four equal slices. Each one of these slices is instrumented with an 8" photo-multiplier tube installed at the top of the detector and looking downwards. The final setup will have three WCD as the one mentioned, distributed in triangular shape and one WCD with 7.3 m in diameter and 5 m of height located in the centre. The data acquisition of this first WCD started in June 2014. In this work the full calibration procedure of this detector will be discused, as well as the report on the preliminary measurements of stability in rate. Effective area and sensitivity to gamma-ray bursts are derived from the LAGO simulation chain, based on Magnetocosmics, CORSIKA and GEANT4. From these results, we discuss the capability of this detector to separate the EM-muon component of extensive air showers.
