Study of Scintillator Strip with Wavelength Shifting Fiber and Silicon Photomultiplier
The performance of the cm plastic scintillator
strip with wavelength shifting fiber read-out by two novel photodetectors
called Silicon PhotoMultipliers (SiPMs) is discussed. The advantages of SiPM
relative to the traditional multichannel photomultiplier are shown. Light yield
and light attenuation measurements are presented. This technique can be used in
muon or calorimeter systems.Comment: 9 pages, 5 figure

The Potential of SiPM as Photon Detector in Astroparticle Physics Experiments like MAGIC and EUSO
We discuss the prospects to use a novel photon detector -the so-called SiPM -for the high energy astroparticle physics experiments EUSO and MAGIC. We explain the principle of these photon sensors and present results obtained with some prototypes. Peak photon detection efficiency (PDE) of the devices available is currently about 20%. Already in its existing form Geiger mode APDs offer a very promising replacement candidate for conventional photomultiplier tubes (PMTs) in both experiments, provided some improvements can be achieved
The SiPM -A new Photon Detector for PET
We have studied a novel semiconductor photon detector (silicon photomultiplier) as a readout for LSO scintillator crystals used in PET detectors. Silicon photomultipliers (SiPMs) of a (1 × 1) mm 2 area were coupled to LSO crystals of (2 × 2 × 10) mm 3 . Two elements were exposed to a 22 Na positron source emitting two 511 keV gamma quanta. Coincidence studies yielded a FWHM of the photopeak spectrum around 35% and a time resolution of 3 ns. Extrapolating from the large area mismatch in the readout area allows us to conclude that the novel SiPM is a very promising element for PET applications
