New large aperture photodetectors for Hyper-Kamiokande are under development and these usability is tested.
For the first proof test, high-QE photomultiplier tubes (51 cm Φ) and hybrid photodetectors (20 cm Φ) have been measured in a 200-ton water tank in Kamioka, Japan.
These installation, calibration and performance evaluation, and development status of other new photodetectors will be presented.

We investigate the performance of photon traps for enhancing the light collection efficiency within the Hyper-Kamokiokande detector. Cerenkov photons enter the trap by going through a dichroic mirror transmitting UV and blue light and reflecting green light. Some Cerenkov photons are detected directly by a PMT while the others are absorbed in a wavelength shifting plate that reemit green...
