Development of the First Detector Line for the Pacific Ocean Neutrino Experiment — •Charlotte Eberhart, Lea Ginzkey, Simeon Bash, Martin Dinkel, Vincent Gousy-Leblanc, Elisa Resconi, and Christian Spannfellner — Technical University of Munich, TUM School of Natural Sciences, Department of Physics, James-Franck-Straße 1, D-85748 Garching bei München, Germany

The Pacific Ocean Neutrino Experiment (P-ONE) aims to be a multi-cubic-kilometre neutrino observatory of the Northeast Pacific Ocean off the coast of Vancouver Island (Canada). P-ONE will measure high-energy astrophysical neutrinos and characterize the nature of astrophysical accelerators. Currently, its first detector line (P-ONE-1) is in production and planned to be deployed in 2025. The one kilometre long line consists of 20 optical and calibration modules and shall serve as a prototype line for the detector, and ultimately be the blueprint for the following detector lines. The optical modules (P-OMs) aim to detect bioluminescence and Cherenkov light with a multi photo-multiplier tube (PMT) configuration. The multi-PMT design of P-OM allows to cope with the high background rates in the depths of the Northeast Pacific Ocean, while their modular and minimal mechanical design makes them easily scalable in vision of the construction of the full P-ONE detector. In this contribution, we will present an overview over the P-ONE-1 design and the production process of the P-OMs.
