A Multi-pixel Geiger-mode APD, often called a Silicon Photomultiplier (SiPM), is a new type of photon counting device made up of multiple APD pixels operated in the Geiger-mode, which started to replace the PMT in a certain parts of photodetection field. Stefan Meyer Institute in Vienna has been working on an evaluation of several kinds of SiPMs from different manufacturers with different sizes of cells, sensitive area. We operate SiPMs in combination with scintillating fiber and Cherenkov radiator to test its potential with special focus on its timing performance, compactness and low-cost. The detectors are going to be applied in experiments like FOPI, AMADEUS and PANDA.
