Title: Characterization and calibration of photomultiplier tubes for the Pacific Ocean Neutrino Experiment — •Josef Pflanz for the P-ONE collaboration — Technische Universität München, Germany

The Pacific Ocean Neutrino Experiment (P-ONE) is a planned cubic-kilometer scale neutrino telescope, designed for high-precision neutrino source searches and long-baseline astrophysical observations. The first detector line is currently under development and will consist of 20 modules, equipped with photomultiplier tubes (PMTs). The Hamamatsu R14374 PMT was selected for this first deployment due to its low transit-time spread, high stability, and overall performance quality. In this talk, I will present the characterization and validation procedures carried out on these PMTs. In particular, I will focus on measurements of quantum efficiency, photon detection efficiency, and the linearity of the PMT response when coupled to P-ONE's dedicated front-end electronics. These results provide essential input for the detector's Monte Carlo simulations and establish a robust framework for future large-scale PMT characterization for the full P-ONE array. The talk will highlight the measurement techniques, calibration methods, and results obtained from a subset of the PMTs.
