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.enAvailable to the World Wide WebParticle PhysicsNeutrino PhysicsCalibrationPhotogrammetryHyper-KamiokandemPMTLight PipeTRIUMFMeasuring Light Distribution of LED Sources for Hyper-Kamiokande Detector CalibrationThesis
