Description

Hyper-Kamiokande (Hyper-K) is a next-generation Water Cherenkov detector designed to study neutrino properties with exceptional accuracy. Precision measurements of neutrino oscillations, charge-parity (CP) violation, atmospheric and solar neutrino studies, as well as proton decay searches, are among the key physics goals of Hyper-K, making accurate detector calibration essential for achieving these scientific objectives.

The Hyper-K light injection (LI) system plays a vital role in ensuring the detector is well-calibrated by injecting controlled pulses of light into the water volume, allowing for precise measurements of the detector’s photomultiplier tubes (PMTs) response, optical response, and water transparency. The inner detector (ID) part of the LI system will consist of 33 injector positions, each equipped with both a narrow-angle beam collimator and a wide-angle beam diffuser.

In this poster, we present an overview of the LI system’s design and its role within the broader calibration framework of Hyper-K. We describe the key components of the system, the layout of injector positions, and the strategies for testing and validating its performance.
