Development of a cost effective PET-like system utilizing organic scintillators and SIPMs to be used for particle tracking — •Esther Constanze Wais, Nadia Böhle, Mario Fink, Thomas Held, Fritz-Herbert Heinsius, Matthias Steinke, and Ulrich Wiedner — Experimentalphysik 1, Ruhr-Universität Bochum, Bochum, Deutschland

Although PET has established itself as a reliable tool in medical applications over the last 20 years, industrial applications have so far been limited. The reason for this are the high costs of constructing a detector on the scale required for industrial purposes. A cost-effective detector has been built. The detector uses long (1000 mm × 20 mm × 20 mm) organic scintillator rods instead of small inorganic scintillator crystals, significantly reducing material and readout costs compared to a conventional detector.
The scintillation light gets detected by SiPMs. Since no SiPMs with the required dimensions were available, four SiPMs are connected in a ’hybrid circuit’ to form a SiPM array of the required size. The goal of the measurements is to investigate the behavior of granular matter in rotary kilns or grate systems in order to test simulations calculations. These calculations will be used in order to make rotary kilns and grate systems more efficient.
