| Popis: | A thermal neutron detector based on ZnS(Ag)/6LiF scintillator, wavelength-shifting fibers (WLS) and silicon photomultipliers (SiPM) is under development at the Paul Scherrer Institute (PSI) for upgrading the POLDI instrument, a pulse-overlap diffractometer. The design of the detector is outlined, and the measurements performed on a single channel prototype are presented. An innovative signal processing system based on a photon counting approach is under development. Its principle of operation is described and its performances are evaluated on the basis of a Monte Carlo simulation. Comment: 8 pages, 15 figures, to be published in the Proceedings of the International Workshop on Neutron Optics and Detectors (NOP&D 2013), 2-5 July 2013, Munich (Ismaning), Germany |
