Abstract
In this study an array of eight 6 mm $\times$ 6 mm area SiPMs was coupled to the end of a long plastic scintillator counter which was exposed to a $2.5 GeV/c$ muon beam at the CERN PS. Timing characteristics of bars with dimensions 150 cm $\times$ 6 cm $\times$ 1 cm and 120 cm $\times$ 11 cm $\times$ 2.5 cm have been studied. An 8-channel SiPM anode readout ASIC (MUSIC R1) based on a novel low input impedance current conveyor has been used to read out and amplify SiPMs independently and sum the signals at the end. Prospects for applications in large-scale particle physics detectors with timing resolution below 100 ps are provided in light of the results.
