High time resolution silicon photomultipliers coupled to plastic scintillatorsDaniel Bemmerer1, Thomas E. Cowan1,2, Marcel Grieger1,2, Tobias P.

Semiconductor-based light detectors, so-called silicon photomultipliers (SiPMs) may in principle replace classical photomultiplier tubes in several applications. Recently, it has been shown [1] that for large, 270×5×5 cm3 plastic scintillator bars SiPM readout with efficiency close to unity and high time resolution is possible, when they are irradiated with 30 MeV single electrons from the ELBE superconducting electron linac. These results will be reviewed, and in addition, recent work at TU Dresden and HZDR on neutron/γ pulse shape discrimination capability of large (9-36 mm2) timing SiPMs coupled to relevant scintillators will be summarized.
