Initial Trigger Strategy for the P-ONE Detector

Abstract

This thesis presents a comprehensive analysis of trigger algorithm efficiency for neutrino event detection in the Pacific Ocean Neutrino Experiment (P-ONE) detector. Investigating muon, electron, and tau neutrinos, the study highlights distinctive interaction characteristics. Beginning with a detailed theoretical background, the research covers the design and components of P-ONE, including the STRAW pathfinder and principles governing muon track and cascade detection. Using a software framework, simulations modeled a muon neutrino flux, monoenergetic muons, and full energy spectra for neutrinos. Trigger algorithm development, reconstructable event selection, and string spacing optimization are discussed. Efficiency analyses, reveal a 70% muon neutrino detection at 10TeV and over 90% efficiency for electron and tau neutrinos at 10TeV. The muon efficiency could also be increased to 85% if a second level trigger algorithm with a factor 50 or more rate reduction can be developed.
