Tests of Silicon Photomultipliers for NeuLAND — •Tobias Reinhardt¹, Daniel Bemmerer², Thomas Cowan^1,2, Zoltán Elekes², Klaus Heidel², Mathias Kempe², Marko Röder¹, Daniel Stach², and Andreas Wagner² — ¹Institut für Kern- und Teilchenphysik, Technische Universität Dresden — ²Helmholtz-Zentrum Dresden-Rossendorf (HZDR)

For upcoming large-scale neutron time-of-flight detectors like NeuLAND at FAIR the use of photomultiplier tubes is still state-of-the-art for the detection of the scintillation light. However, recent developments in the field of Silicon Photomultiplier indicate that they may also be suitable for this type of application. 3 × 3 mm² prototypes from various manufacturers were tested with small scale scintillators and a Sr-90 source. Using inhouse developed preamplifier boards, first time resolution measurements with a 270 cm long NeuLAND BC-408 scintillation bar were carried out at the electron accelerator ELBE.
