  1. 32. Study of 144 Channel Multi-Anode Hybrid Avalanche Photo-Detector for the Belle II RICH Counter
    Dr Ichiro Adachi (KEK)
    13/06/2012, 16:00
    Oral presentation
    New hybrid avalanche photo-detector has been developed as a photon sensor for the Belle II RICH counter. Single-photon response was investigated in the presence of a magnetic field and excellent performance was demonstrated. In addition, the radiation damage was studied in detail. By building a prototype consisting of 6 photo-detectors, a test beam experiment was carried out. We...

  2. 35. Recent progress in vacuum photon detectors from Hamamatsu
    Mr Yuji Yoshizawa (Hamamatsu Photonics)
    13/06/2012, 16:20
    Oral presentation
    Hamamatsu Photonics has developed 12-inch large size PMT for Neutrino physics experiments and 3-inch metal bulb PMT for Dark Matter experiments. These PMTs and other new products will be shown in this presentation.

  3. 59. Study on large area photomultipliers with super bialkali photocathode
    Dr Emanuele Leonora (INFN section of Catania)
    13/06/2012, 16:40
    Oral presentation
    Photomultipliers with large photocathode area have been widely used in proton decay, astrophysics and neutrino detectors in recent years, since large detection volumes can be reached with a reduced number of detectors. The sensitivity of a photomultiplier is described in terms of its quantum efficiency (QE), i.e. the number of photoelectrons emitted from the photocathode divided by the number...

  4. 6. Lifetime measurements of recent Microchannel-Plate PMTs
    Alexander Wolfgang Britting (Friedrich-Alexander-Univ. Erlangen (DE))
    13/06/2012, 17:00
    Oral presentation
    The PANDA experiment at FAIR will study ppbar-collisions at an energy range of 1 GeV to 15 GeV. The particle identification will be done with two DIRC (detection of internally reflected Cherenkov light) detector systems. Attractive photo sensors for these DIRCs are micro-channel plate (MCP) photomultipliers (PMT), which provide an excellent time resolution of <50 ps and can stand high...

  5. 8. A new design of large area MCP-PMT for the next generation neutrino experiment
    Yuekun Heng (Institute of High Energy Physics)
    13/06/2012, 17:20
    Oral presentation
    A new design of large area MCP-PMT for the next generation neutrino experiments is proposed. The main motivation of the design is to improve the quantum efficiency (photo detection efficiency) of the PMT. Two sets of small MCP units, the transmission photocathode coated on the front hemisphere and the reflection photocathode coated on the rear hemisphere are assembled in the same glass...
