A SiPM-based gamma-ray detection module for substituting bulky Photomultiplier Tubes in the readout of large scintillation crystals is presented. The system can be coupled to scintillators up to 3 inches in diameter, with state-of-the-art energy resolution (2.6% at 662 keV) and 80 keV - 20 MeV energy Dynamic Range, simultaneously achieved for the first time. Position sensitivity can also be achieved. Measurements show that a complete replacement of PMTs with SiPMs is already possible thanks to enhancements in silicon technology and lowering costs, making SiPMs a severe contender in many fields now dominated by vacuum-tubes technology.

Abstract

A SiPM-based gamma-ray detection module for substituting bulky Photomultiplier Tubes in the readout of large scintillation crystals is presented. The system can be coupled to scintillators up to 3 inches in diameter, with state-of-the-art energy resolution (2.6% at 662 keV) and 80 keV - 20 MeV energy Dynamic Range, simultaneously achieved for the first time. Position sensitivity can also be achieved. Measurements show that a complete replacement of PMTs with SiPMs is already possible thanks to enhancements in silicon technology and lowering costs, making SiPMs a severe contender in many fields now dominated by vacuum-tubes technology.
