Abstract
The Hyper-Kamiokande experiment uses water-Cherenkov detectors to study neutrino oscillation and charge conjugation parity (CP) violations with high precision.
To reduce systematic errors, multi-photomultiplier tube modules (mPMTs) that comprise the Cherenkov photon detectors will include LED light sources for calibration
purposes. This report describes how the LEDs are incorporated into mPMT design,
how the distribution of LED light is measured, and discusses how the LEDs will be
used for the experiment calibration upon detector completion.
