:Development of scintillation detectors based on silicon photomultipliers for high-energy gamma-ray applications
Advisor: FIORINI CARLO ETTOREAbstract:
Silicon PhotoMultipliers (SiPMs) are an emerging solid-state technology as to be considered a promising alternative to the consolidated PhotoMultiplier Tubes (PMTs) in many low energy medical imaging applications as TOF-PET thanks to their excellent timing performances and magnetic fields compatibility. Nowadays the research efforts are focused on the coupling of these devices with fast and thick state-of-the-art scintillators for high-energy applications as nuclear physics and prompt gamma imaging detection for proton therapy. In this context, the goal of the activity is to develop a SiPMs-based gamma-ray spectrometer and imaging module that can be innovative in both prompt gamma imaging and nuclear physics applications. In the field of prompt gamma imaging that module has to be designed for real-time measurement of a 2D projection of the proton beam range in Proton Therapy, with a pixelated structure that allows to decrease the count rate specifications. In addition the module should allow to read the crystals typically adopted in nuclear physics experiments such as 2" and 3" thick LaBr3, allowing spectroscopic and imaging results in line with PMTs standards.
