We present the technology for very compact hybrid circuits with one water cooled LTCC substrate, Silicon Photomultipliers and ASICs for Positron Emission Tomography / Magnetic Resonance Tomography Applications. The SiPM modules with an area of 32.8 by 32.0 mm2 contain 12×12 SiPMs in a pitch of 2.5 mm2. The readout of the 144 channels is done by four highly specialized ASICs. The water cooling channels...
We present a very compact photo sensor module with an area of 32.8 × 32.0mm2 containing 12 × 12 Silicon Photomultipliers (SiPMs) in a pitch of (2.5mm)2. The readout of the 144 channels is done by highly specialized PETA5 ASICs (Position Energy Timing Asic) which offer self triggered hit detection (including neighbor logic and fast veto mechanisms), time stamping with 50ps bin width and digital amplitude...
We present a new Silicon Photo-Multiplier topology (Interpolating SiPM, ISiPM), able to reach sub-millimeter spatial resolution in photon cluster identification. SiPMs are becoming widely used in different applications, from medical imaging to high energy physics, as γ-ray detectors, coupled with suited scintillating crystals. The intrinsic spatial resolution in such application is limited by the...
Silicon Photo Multiplier are becoming widely used, coupled with suited scintillating crystals, as gamma-ray detectors in high energy physics and medical imaging applications. We present a novel device topology, able to reach sub-millimeter spatial resolution with very few readout channels. The basic idea consists to connect each cell of a SiPM to one of the several readout channels. A cluster of photons,...
