The Pacific Ocean Neutrino Experiment: STRAW-b as a pathfinder — •Eva Laura Winter, Christian Spannfellner, and Elisa Resconi — Technische Universität München, Germany

The Pacific Ocean Neutrino Experiment (P-ONE) is a collaboration of Ocean Networks Canada (ONC), the Technical University Munich (TUM) and other Canadian/German institutes with the aim of building a large-scale neutrino telescope in the Northeast Pacific Ocean. Two pathfinders have been developed and successfully deployed, as part of the NEPTUNE observatory, established by ONC, at Cascadia Basin, which will also host P-ONE. The first pathfinder STRAW (STRings for Absorption length in Water) was deployed in June 2018 and has measured the optical properties of the deep Pacific Ocean. Moreover, it is also monitoring the in-situ background rates due to K40 decay and bioluminescence. Subsequently, the second pathfinder STRAW-b, deployed in September 2020, aims to further characterize the deployment site. For this, it is equipped with six specialized modules, two LiDARs, three spectrometers and one muon tracker. The talk covers technical details and will give an overlook of preliminary results of the pathfinders.
