    "abstract": "The application of reach-through avalanche photodiodes (R\u0027APD) as a\nphotodetector for scintillator tiles has been investigated. The light collected\nby WLS fibers (0.84mm and 1mm diameter) embedded in the scintillator has been\ntransmited to the 0.5mm2 active surface of APD by clear optical fibers and\noptical connectors. A low noise charge sensitive preamplifier (approximately\n400 electrons equivalent noise charge) has been used to gain the photodiode\nsignal. Various configurations of tile-fibre systems, suitable for CMS and LHCb\nexperiments at LHC have been studied using cosmic muons and muon beam at SPS at\nCERN. In order to optimize the performance of APD, measurments in the\ntemperature range from -10C to +25C have been done. The MIP detection\nefficiency and electron/MIP separation have been estimated in order to\ndetermine applicability of the readout for LHCb preshower.",
