  1. 25. Hybrid Photo-Detector study at Kamioka
    Dr Yasuhiro NISHIMURA (ICRR)
    23/08/2012, 10:05
    Hybrid Photo-Detector (HPD) with an avalanche diode is one of the photo-sensor candidates for Hyper-K. It is considered to have a better performance in lower price than PMT in Super-K. We started a study of an 8-inch HPD developed by Hamamatsu Photonics and that of a 20-inch diameter will be provided within a few years. In Kamioka mine we have a plan to test the HPD in a 200-ton water...

  3. 7. Mechanical Performance of Large Format Underwater Photo-multiplier
    Dr Jiajie Ling (Brookhaven National Laboratory)
    23/08/2012, 11:10
    Large, deep, well shielded liquid detectors have become an important technology for the detection of neutrinos over a wide dynamic range of a few MeV to TeV. The critical component of this technology is the large format semi-hemispherical photo-multiplier tube with diameters in the range of 25 to 50cm. The survival of an assembled array of these photo-multiplier tubes under high hydrostatic...

  4. 34. Photomultiplier Tube Glass Failure in Neutrino Detection: Challenges and Opportunities
    Prof. S. K. Sundaram (Kazuo Inamori School of Engineering, Alfred University)
    23/08/2012, 11:25
    We have undertaken a detailed investigation of photomultiplier tube (PMT) glass fracture at Alfred University, in support of Brookhaven National Laboratory’s Long Baseline Neutrino Experiment (LBNE). The strength and lifetime prediction of the PMT glass are crucial to the success of the neutrino detection. Glass fracture is statistical in nature. Glasses are generally under constant state of...

  5. 16. Photo-detector development for maximizing the overall photon detection efficiency
    Dr Fabrice Retiere (TRIUMF)
    23/08/2012, 13:00
    The baseline Hyper-K concept relies on 99,000 20” photomultiplier tubes (PMTs) to provide 20% photo-coverage. We are investigating solutions that would enhance the photo-coverage without compromising either contrast or timing resolution. Contrast roughly quantifies the fraction of photons detected that retain the Cerenkov light directional information over the total number of photons detected,...

  6. 44. Development of a Large Area Photodetector with a Fast Phosphor Anode
    Prof. Toru Iijima (Nagoya University)
    23/08/2012, 13:15
    The next generation neutrino experiments like the Hyper-Kamiokande requires cost-effective ways to instrument large volumes with O(10^(4−5)) pieces of photodetectors. Such photodetectors are required to have good effective quantum efficiency, large active area, high gain to allow use of simple and cheap electronics, and good time resolution to reconstruct the wave front of the Cherenkov cone....
