Contribution
It provides a detailed simulation and comparison of WCD responses to GRBs, enhancing understanding of detector sensitivity and behavior during high-energy astrophysical events.
Findings
Simulations match observed data, validating detector models.
LAGO's sensitivity to GRBs is characterized through these simulations.
Response behavior of WCDs to gamma-ray showers is clarified.
Abstract
In order to characterise the behaviour of Water Cherenkov Detectors (WCD) under a sudden increase of 1 GeV - 1 TeV background photons from a Gamma Ray Burst (GRB), simulations were conducted and compared to data acquired by the WCD of the Large Aperture GRB Observatory (LAGO). The LAGO operates arrays of WCD at high altitude to detect GRBs using the single particle technique. The LAGO sensitivity to GRBs is derived from the reported simulations of the gamma initiated particle showers in the atmosphere and the WCD response to secondaries.
