Application of Hamamatsu MPPC to T2K Neutrino Detectors

A special type of Hamamatsu MPPC, with a sensitive area of 1.3×1.3 mm containing 667 pixels with 50×50 μm each, has been developed for the near neutrino detector in the T2K long baseline neutrino experiment. About 60 000 MPPCs will be used in total to read out the plastic scintillator detectors with wavelength shifting fibers. We report on the basic performance of MPPCs produced for T2K.

Mass production test of Hamamatsu MPPC for T2K neutrino oscillation experiment

In the T2K near neutrino detectors, about 60 000 Hamamatsu Multi-Pixel Photon Counters (MPPCs) will be used. The mass production of MPPC has started in February 2008. In order to perform quality assurance and to characterize each device, we have developed an MPPC test system. For each MPPC, gain, breakdown voltage, noise rate, photo detection efficiency, and cross-talk and after-pulse rate are ...

Target Design and R&D of J-PARC E06 TREK experiment

TREK is an experiment to search for violation of time reversal invariance (T-violation) in the kaon decay of K π0μ ν planned at the Japan Proton Accelerator Research Complex (J-PARC). The active target is one of the primal detector elements of the TREK detector system. Kaons come from the beam line, stop and decay in the target. The active target consists of a bundle of scintillating fiber and ...

Directly Coupled Tiles as Elements of a Scintillator Calorimeter with MPPC Readout

We present results on the direct i.e. fiberless coupling of scintillator tiles to Multipixel Photon Counters (MPPC). The fiberless option has the potential of simplifying the assembly and construction of a finely-segmented scintillator-based calorimeter with MPPC readout. In this paper we show detailed studies on the response and uniformity of directly coupled tiles and describe our concept for...
