Abstract

The Pacific Ocean Neutrino Experiment (P-ONE) is a planned water-based Cherenkov neutrino
telescope that will be located off the west coast of Canada. P-ONE will observe high-energy
astrophysical neutrinos, aiming to identify the sources where they are produced, and will allow
long-term in-situ studies of bioluminescence in the Cascadia Basin. The detector will be composed of instrumented mooring lines, which, along with the existing deep-sea infrastructure of the NEPTUNE observatory, make the design easily scalable. The first phase of the experiment, called P-ONE-1, is the first complete detector line and is instrumented with 20 modules spanning one kilometer. P-ONE-1 will serve as a test for all the newly developed systems and infrastructure and will pave the way for the future phases. This contribution will give an overview of the current status of the construction of the first line, the expected performance and the recent design innovations.
