“…In this work the GEANT4 package was chosen due to the flexibility it provides for scaling the simulation to a large detector arrays for future investigations. Simulations detailing the response of SiPMs have also been developed previously [11,17,18], where the influence of noise effects on the SiPMs response are considered. Here the results of a C++ plugin tool for GEANT4 are discussed, developed in mind of reproducing specifically the fast timing response of a SiPM, coupled to a LYSO scintillator crystal.…”

In recent years the silicon photomultiplier has been investigated as an alternative to the traditional photomultiplier tube in a range of applications, including Time-of-flight Positron Emission Tomography (TOF-PET). In this paper we discuss a GEANT4 simulation framework, which has been developed to drive the design of a scalable TOF-PET apparatus to be built at the Rutherford Appleton Laboratory, UK. First results presented in this paper simulate the response of an Hamamatsu Multi-Pixel Photon Counter (S10362-33-050c) coupled to LYSO scintillating crystals, with focus on the timing response of coincidence signals.

“…We placed the scintillator with the 4×30 mm 2 face in front of the aperture, in order to maximize the sensitive area, and with the two SiPMs coupled at the opposite lateral faces. This novel architecture is being studied by several groups [25][26][27] for PET applications, in order to build compact gamma detector modules having a limited number of channels. In this configuration, the position of interaction of the gamma ray along the longer axis of the crystal is completely random, and this causes a high jitter in the number of photons reaching each SiPM, dramatically affecting the energy and consequently the timing resolution.…”

Silicon Photomultipliers (SiPMs) are single-photon detectors currently used in many applications as a valid alternative to Photomultiplier Tubes (PMTs). In fact, SiPMs present several advantages compared to PMTs, in terms of size, ruggedness, insensitivity to magnetic fields and voltage supply.In this work, we evaluated the use of SiPMs produced by FBK (Fondazione Bruno Kessler)-AdvanSid (Trento, Italy) in Positronium Time Of Flight (Ps TOF) technique. The aim of this technique is the study of the energy of Ps emitted by porous media for advanced experiments in the field of antimatter physics and, in the future, for open porosities characterization.The TOF spectrometer in operation at the positron beam of the University of Trento (Italy) is based on five gamma detectors composed of NaI(Tl) scintillators coupled to PMTs. We compared the performance of one of these standard detectors against a detector formed by two 4×4 mm 2 SiPMs coupled to a 4×4×30 mm 3 LYSO (Cerium-doped Lutetium Yttrium Orthosilicate) scintillator. The LYSO+SiPM detector was characterized for timing and energy resolution as well as for the background emission level.It is shown that SiPMs, thanks to their small size and versatility, can be coupled successfully to small scintillators, obtaining more compact detectors with respect to the NaI(Tl)+PMT detectors. The design of an array of detectors with wide angular acceptance and spatial resolution is discussed in order to improve the performances of Ps-TOF setups.

“…Therefore, precise models of SiPM signal generation are necessary to find the optimal parameters for a specific task. Pioneering work has already been presented in the modelling and the theoretical analysis of SiPM signals coupled with scintillating crystals [6][7][8]. However, these models do not include the complete characteristics of a SiPM and may thus not offer sufficient accuracy in all cases.…”

A Monte-Carlo model of a SiPM coupled to a scintillating crystal

The silicon photomultiplier (SiPM) is a promising photodetector for a number of applications. In this paper, we present a Monte-Carlo based statistical model, which includes the fundamental device characteristics of the SiPM, such as fill factor, quantum efficiency, Geiger discharge probability, afterpulse probability, crosstalk probability, cell size, non-linearity and dark count rate. The impact of these parameters on the performance of a SiPM coupled to a scintilla-ting crystal were studied. In this work special focus was put on the influence of different parameters on the energy resolution of a SiPM coupled to a LYSO, which provides important guidelines for further optimization of SiPMs for positron emission tomography. The developed model shows that afterpulses and the crosstalk have little influence on the detector performance in terms of energy resolution. The energy resolution of the SiPM with 400 cells/mm 2 is strongly affected by the recovery time of the detector. It is due to the combination of the high PDE and short recovery time that a SiPM with 400 cells/mm 2 shows better performance in term of energy resolution when coupled with LYSO compared to a SiPM with 1600 cells/mm 2 .
