Description
The Pacific Ocean Neutrino Experiment (P-ONE) is a new project to instrument more than one cubic kilometre of the Northeast Pacific Ocean off Vancouver Island (Canada) and use it non-invasively as a next-generation neutrino telescope. P-ONE will measure high-energy astrophysical neutrinos and characterise the nature of astrophysical accelerators. The NEPTUNE observatory, an established deep-sea facility hosted by Ocean Networks Canada (ONC), greatly supports P-ONE by providing power and communication. The optical properties of the deployment site, the NEPTUNE node in the Cascadia Basin, at a depth of 2660 metres, have been accessed by two pathfinder experiments deployed in 2018 and 2020, respectively. The next step is the conception, design, construction, and deployment of the first P-ONE line (P-ONE-1), which will serve as a blueprint for the full detector array. This first line will instrument the ocean with optical modules, housing PMTs and readout electronics, distributed over a hybrid backbone cable of about 1 km length. In this contribution, we will present the status of P-ONE-1 and the associated optical and calibration instruments.
