38. Overview of the photodetector development

Dr Shoei Nakayama (Kamioka Observatory, ICRR, University of Tokyo)

21/07/2014, 12:40

I will present a brief introduction of current activities in the photodetector sub-WG and the plan for the photodetector development.

43. Viability test of photodetectors in the water tank

Mr Yuji Okajima (Tokyo Institute of Technology)

21/07/2014, 12:50

In August 2013, eight hybrid photodetectors (HPDs) with 20-cm diameter and five 50-cm High-QE (HQE) photomultiplier tubes (PMTs) have been installed into a water tank and a validity test started. I will present a progress and results on the 20-cm HPDs and 50-cm HQE PMTs test in the water tank and a status and plan for a next test with new 50-cm box-and-line dynode PMTs.

42. New 50-cm diameter photodetectors

Mr Yusuke Suda (University of Tokyo)

21/07/2014, 13:10

We have been developing 50-cm diameter Box&line PMTs and Hybrid Photo-Detectors (HPDs) for Hyper-Kamiokande. Both have excellent performance compared with Super-Kamiokande PMT. We present the principle and basic performance (typical waveforms, timing response, dark count rate, linearity and response uniformity) and the result of the pre-calibration for a test in a 200-ton water Cherenkov...

37. A status and prospect of the photodetector development in Kamioka

Dr Yasuhiro NISHIMURA (ICRR)

21/07/2014, 13:30

The R&D of photosensors and plan in Kamioka, Japan, are presented.
