Description
Hyper-Kamiokande (Hyper-K) is to be the next generation of large-scale water Cherenkov detectors and aims to obtain exciting results in many fields such as the study of CP violation in the leptonic sector, the search for proton decay and the study of accelerator, atmospheric, solar neutrinos and neutrinos from astronomical origin.
The Hyper-K Far Detector will be characterized by a hybrid configuration that combines the 20" PMTs, already adopted in Super-K, with the multi-PMT (mPMT) modules, a novel technology first designed for the KM3NeT experiment.
The mPMT module, based on a pressure vessel instrumented with 19 multiple small diameter (7.7 cm) photosensors, each one with a different orientation, readout electronics and power, offers several advantages as increased granularity, reduced dark rate, weaker sensitivity to Earth’s magnetic field, improved timing resolution and directional information with an almost isotropic field of view.
We are completing the R&D of the mPMT prototype and are now starting the preparation for mass production.
In this contribution the results of the tests performed on the first protoypes as well as the procedures for quality assurance and Hyper-K’s mPMT program will be discussed.
