PD1. Selection of Photomultipliers for Cerenkov Telescope Array facility Maxim Shayduk (MPI-

Munich)The future ground-based gamma-ray facility - Cerenkov Telescope Array (CTA) is aiming for sensitivity of ~1 mCrab at energies above 200 GeV, That is about one order of magnitude higher compared to currently operating instruments H E S Shigher compared to currently operating instruments H.E.S.S., MAGIC and VERITAS. In order to provide high sensitivity and low energy threshold the photosensors should have high photon gy p g pdetection efficiency (PDE), low afterpulsing rate and good single photo electron amplitude resolution. Photosensors of Cherenkov telescopes are permanently exposed to the background light of the night sky, so the long life time and low fatigue are also neccessary conditions Various photomultipliers of 1 2 inch sizeneccessary conditions. Various photomultipliers of 1-2 inch size from PHOTONIS and HAMAMATSU were tested in MPI for Physics in Munich. Comparative measurements of quantum

PD3. Study of 144-Channel Multi-Anode Hybrid Avalanche Photo-Detector for the Belle RICH Counter

Samo Korpar (University of Maribor)

For the Belle detector upgrade we have been conducting R&D onFor the Belle detector upgrade, we have been conducting R&D on a proximity focusing RICH counter using a silica aerogel radiator. As a photon detector, we have newly developed a multi-anode hybrid avalanche photo-detector (HAPD) with Hamamatsu. At the bench, we found a distinct single photo-electron peak with S/N>6

d it t t l i d t b 40000 Thand its total gain was measured to be over 40000. These performances were also tested under a magnetic field of 1.5 Tesla We then carried out a beam test at KEK A prototypeTesla. We, then, carried out a beam test at KEK. A prototype counter was built with 6 HAPDs in the 2x3 array. With this system, we successfully observed a clear Cherenkov ring image.

23

Preliminary results show Cherenkov angle resolution of 12 mrad with 5 photo-electrons, which is consistent with our expectation.

SIPM1 4. A Study to Enhance the UV Sensitivity of Geiger mode Avalanche Photodiodes by Wavelength Shifter Coatings

Eckart Lorenz (MPI-Munich)

Current p-on-n Geigermode avalanche photodiodes (G-APD) have their peak sensitivity around 400-450 ( ) p ynm with a rapid drop in sensitivity in the UV. For certain applications, such as Cherenkov detectors (air pp (Cherenkov telescopes for ground-based gamma-ray astronomy, RICH detectors,...) or air fluorescence y )detectors for the study of the highest energy cosmic rays, a high UV sensitivity is needed. This can be y g yachieved by an inexpensive wavelength shifter coating of the G-APDs. Measurements are presented.

27Advantages and limitations will be discussed.

SIPM7. The Measurements of 2200 Silicon Photomultipliers for the EMMA Cosmic Ray Underground Experiment

Bayarto Lubsandorzhiev (University of Tuebingen)The results of extensive tests of 2200 silicon photomultipliers for the EMMA cosmic ray muons underground experiment are presented. The silicon photomultipliers are multi-pixel Geiger-mode avalanche photodiodes produced by the CPTA Company inmode avalanche photodiodes produced by the CPTA Company in Moscow, Russia. The photodiodes were selected and tested for use in plastic scintillator counters of the EMMA underground p gexperiment, which is presently being under construction in Pihasalmi mine in Central Finland. The results cover thorough studies of the main parameters of the photodiodes which are crucial for such kind of application: photon detection efficiency, dark current gain recovery time and breakdown and operationaldark current, gain, recovery time and breakdown and operational voltages. All tested photodiodes were classified into separate groups with close parameters for use in scintillator counters
