A new detection system was designed for muography applications, based on scintillator bars and SiPM read-out. Monte-Carlo simulations were performed to evaluate detector characteristics (efficiency, acceptance, resolution) aiming for secondary muon trajectory reconstruction.
The basic unit of this detector, consisting of a scintillator bar with an optical fiber waveguide and two SiPM devices collecting the light signal at both ends of the fiber, was submitted to tests using cosmic-ray muons. The temporal resolution of this base unit was determined using the time-of-flight method. Temperature dependence of the SiPMs and uncertainties induced by the non-uniformity of the scintillator and optical fibers have also been investigated, taking into account specific requirements for muography applications.
