GEANT4 studies on the propagation and detection of scintillation light in long thin YAP crystals / Ciocia, F (INFN, Bari) ; Braem, A (CERN) ; Chesi, E (CERN) ; De Leo, R (INFN, Bari) ; Joram, C (CERN) ; Lagamba, L (INFN, Bari) ; Nappi, E (INFN, Bari) ; Séguinot, J (CERN) ; Vilardi, I (INFN, Bari) ; Weilhammer, P
The response to γ-rays of long thin polished or wrapped YAP:Ce scintillator bars read out at both edges by photomultipliers has been studied by means of GEANT4 simulations with the aim to investigate the capability of the charge division method to reconstruct the gamma interaction point in the crystal. The GEANT4 simulations took into account the optical properties of the scintillator like absorption, reflection, and diffusion during the passage of the light through the crystal. [...]

Scintillator studies for the HPD-PET concept / Braem, D (CERN) ; Chesi, Enrico Guido (CERN) ; Ciocia, F (INFN Bari) ; De Leo, R (INFN Bari) ; Joram, C (CERN) ; Lagamba, L (INFN Bari) ; Nappi, E (INFN Bari) ; Séguinot, Jacques (CERN) ; Vilardi, I (INFN Bari) ; Weilhammer, P (CERN)
The spatial, energy, and time resolutions of 10 cm long polished YAP:Ce and LYSO:Ce crystals have been measured. The work is part of the novel HPD-PET concept, based on a full three-dimensional, free of parallax errors, reconstruction of the γ-ray interaction point in 10–15 cm long scintillators. [...]

Recent Results with a segmented Hybrid Photon Detector for a novel parallax-free PET Scanner for Brain Imaging / Braem, André (CERN) ; Chesi, Enrico Guido (CERN) ; Joram, Christian (CERN) ; Mathot, Serge (CERN) ; Séguinot, Jacques (CERN) ; Weilhammer, Peter (CERN) ; Ciocia, F (INFN Bari) ; De Leo, R (INFN Bari) ; Nappi, E (INFN Bari) ; Vilardi, I (INFN Bari) et al.
We describe the design, fabrication and test results of a segmented Hybrid Photon Detector with integrated auto-triggering front-end electronics. Both the photodetector and its VLSI readout electronics are custom designed and have been tailored to the requirements of a recently proposed novel geometrical concept of a Positron Emission Tomograph. [...]
