Description

Hyper-Kamiokande will deploy about 3,600 3-inch PMTs in its outer detector to veto cosmic-ray backgrounds and improve event classification. Each PMT will be paired with a wavelength-shifting plate to increase the active photon-collection area. Two candidate designs, both with waterproof casings, are currently being evaluated through coordinated measurements across several laboratories. This talk will present the status of these studies, the selection process, and the quality control and deployment plans for the outer detector PMTs.
