Study of scintillator strip with wavelength shifting fiber and silicon photomultiplier

The performance of the 200×2.5×1cm3 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.
