Multi-PMT detectors for Hyper-Kamiokande
The Hyper-Kamiokande Far Detector is a 258 kilotonne water Cherenkov detector under construction in Kamioka, Japan. The experiment will use accelerator, atmospheric, and astrophysical neutrinos to search for new physics with unprecedented statistical accuracy. Light from neutrino interactions is detected by 20,000 20" PMTs and 800 multi-PMT detectors, which are an important part of the calibration of the detector. The Canadian LED-mPMT variants contribute to the suppression of the systematic errors of the experiment. The mPMTs provide increased angular resolution and are less vulnerable to stray magnetic fields, allowing accurate calibration of the Far Detector and increased energy resolution. The LED-mPMT variant includes 5 ultra-fast LED-based light injectors with custom collimators and diffusers. This will aid in measuring the optical properties of the ultra-pure water and determine accurately the angular response of the 20" PMTs in Hyper-Kamiokande.
In this talk I will present the LED-mPMT detectors being assembled and commissioned at Carleton University. I will describe their operation at the Far Detector and the unique role they play towards the control of systematic errors in the Hyper-Kamiokande Experiment.
