Description
Silicon Photomultipliers (SiPMs) have become essential photodetectors in a wide range of applications—from medical imaging to high-energy physics (HEP)—thanks to their excellent timing capabilities, compact form factor, and ease of integration. These demanding fields require continuous innovation, particularly in the development of next-generation photodetectors and advanced system integration techniques. FBK is actively addressing these challenges by developing new SiPM technologies with customized Through-Silicon Via (TSV) solutions, enabling 2.5D and 3D integration with readout electronics. This architecture allows for high-density interconnections and fine detector segmentation, reducing output capacitance per channel, preserving signal integrity, and enhancing timing performance. Two projects adopting this approach are PETVision, focused on high-resolution Time-of-Flight PET for medical imaging, and COSMOPORT, which aims to develop next-generation scanner systems for cargo inspection using Muon Transmission Tomography (MTT). These advancements will support the ongoing improvement of FBK SiPM technology, enabling enhanced performance across diverse fields—from medical imaging to large-scale physics research—with meaningful societal impact.
