Description
The P-ONE (Pacific Ocean Neutrino Experiment) is a future cubic km size, water Cherenkov neutrino telescope that will be located in the Pacific Ocean off the coast of Canada. This telescope will contribute to the search for astrophysical neutrinos sources, test improved detection and calibration techniques, and conduct valuable oceanographic measurements.
The first line of the detector, namely P-ONE-1, is currently under production. The P-OM (P-ONE Optical Module), consists of 16 three inch PMTs as well as a series of calibration devices (flashers, acoustic, axicon, muon scintillator) which will characterize the water optical properties and measure the initial performance of the line. The PMT waveforms are digitized by a 16-channel (200 MHz) Analog to Digital converter (ADC) with a timing system providing an estimated accuracy of 0.1 nsec. After assembling the P-OM, in order to create an accurate simulation of the mooring line and verify that the modules function correctly, it is essential to characterize and calibrate the sensors.
Therefore, a dedicated automatic calibration setup (consisting of multiple light sources and rotation stages) was developed at the Technical University of Munich to perform quality control of the P-OM hemispheres and measure the properties of the PMTs. This contribution will discuss the different optical module features, sub-systems as well as the measurements performed on the optical module.
