Abstract:
'The Pacific Ocean Neutrino Experiment (P-ONE) collaboration, currently forming around Ocean Networks Canada (ONC), including Canadian as well as German universities, pursues the goal of constructing a new large-scale neutrino telescope at the 2600 m deep Cascadia Basin, off the Canadian coast. While the instrumented volume needs to be at least on the order of km³ for the physics goals of P-ONE to be met, the density of photo sensors needs to be kept as low as possible in order to optimize construction costs. This naturally puts very high demands on the optical properties of the water at the site, which should ideally exhibit minimal extinction and scattering in order to optimize the light yield and timing needed for the reconstruction of neutrino-induced Cherenkov light flashes. Another important aspect is the light background from natural sources, such as bioluminescence and K40 radioactive decay.rnIn order to evaluate the proposed site for P-ONE, two pathfinder missions have already been deployed successfully, one in 2018 and the other in 2020. In this presentation we will show the results from the first mission that was primarily aimed at evaluating the optical properties of the site in terms of absorption, scattering and backgrounds.'
