Pacific Ocean Neutrino Experiment (P-ONE) is a proposed undersea neutrino detector with pathfinders already deployed, targeting a 70-string (1400 digital optical module) full deployment. By deploying in a deep-sea environment, scattering is reduced relative to in-ice experiments, allowing event resolutions at or below a tenth of a degree. Our current event simulation is based on methods developed for existing gigaton-volume neutrino detectors, simulating a particle hypothesis to produce photons and secondary particles, which are propagated through the detector medium to collision with the detection module’s photocathode, and through its electronics chain. A panel of basic and robust event reconstructions are applied. In this poster, we present a first detailed event simulation and reconstruction, and estimate the projected discovery potential fluxes for point sources of astrophysical neutrinos in P-ONE.
