Imaging Air Cherenkov Telescopes and Ground Based Arrays are the major contributors to Gamma
Ray astronomy at ground level. The Southern Wide-Field Gamma-ray Observatory (SWGO) will be a
water Cherenkov Array located in the Atacama Desert in Chile that will monitor the VHE and UHE sky.
The Naples group has proposed a multi-photomultiplier (multiPMT) detector for SWGO, based on
KM3NeT and HyperKamiokande designs, consisting of seven 3-inch outward-facing PMTs. A multiPMT
photosensor offers intrinsic sensitivity to the directionality of incoming particles Cherenkov light cone,
large dynamical range and increased time resolution. My work demonstrates the advantages of the
multiPMT over the single-PMT alternative. I developed a detailed simulation of the multiPMT and
studied ways to improve Cherenkov light collection and upgrade the original design of the prototype. I
also investigated the muon tagging capabilities of multiPMTs in water Cherenkov tanks using various
machine learning models and explored the potential of using the multiPMT's directional sensitivity for
neutrino detection in the context of Multimessenger Astronomy.
