Metascintillator pulse feature and shape analysis to detect photoelectric interactions and energy sharing / Konstantinou, G (Valencia U., IFIC) ; Latella, R (Valencia U., IFIC) ; Molliner, L (Valencia U., IFIC) ; Zhang, L (Valencia U., IFIC) ; Benlloch, J M ; Gonzalez, A J ; Lecoq, P (Valencia U., IFIC ; CERN)
Metascintillators are scintillator topologies whose principle is based on sharing the energy of an impinging gamma ray between their composing materials. These can be a dense crystal such as LYSO or BGO to retain a high gamma absorption probability, and a fast-emitting compound such as BC-422, EJ232 or BaF$_{2}$ contributing to its light production kinetics.

Toward a second generation of Metascintillators using the Purcell effect / Lecoq, P (CERN) ; Kaminer, I (Technion) ; Schultzman, A (Technion) ; Schütz, R (Technion) ; Kurman, Y (Technion) ; Lahav, N (Technion) ; Dosovitskiy, G (Technion) ; Bekenstein, Y (Technion) ; Konstantinou, G ; Latella, R et al.
We are developing a new scintillation concept, which will become part of the second generation of metascintillators. The first generation approached 100 ps equivalent coincidence time resolution (CTR) in a PET scanner configuration with LYSO/plastic and LYSO/BaF2designs, and reached 200 ps with much cheaper BGO/plastic and BGO/BaF2heterostructures. [...]

Metascintillators: New Results for TOF-PET Applications / Lecoq, P (CERN ; Valencia, Polytechnic U.) ; Konstantinou, G ; Latella, R ; Moliner, L (Valencia, Polytechnic U.) ; Nuyts, J (Leuven U.) ; Zhang, L ; Barrio, J (Valencia, Polytechnic U.) ; Benlloch, J M (Valencia, Polytechnic U.) ; Gonzalez, A J (Valencia, Polytechnic U.)
We report on the progress on a first generation of realistic size metascintillators for time-of-flight PET. These heterostructures combine dense LYSO or BGO plates, interleaved with fast scintillator layers producing a bunch of prompt photons from the energy leakage of the recoil photoelectric electron. [...]

Performance evaluation of multiple (32 channels) sub-nanosecond TDC implemented in low-cost FPGA / Lichard, P (CERN) ; Konstantinou, G (CERN) ; Vilanueva, A Villar (CERN) ; Palladino, V (CERN)
NA62 experiment Straw tracker frontend board serves as a gas-tight detector cover and integrates two CARIOCA chips, a low cost FPGA (Cyclon III, Altera) and a set of 400Mbit/s links to the backend. The FPGA houses 16 pairs of sub-nanosecond resolution TDCs with derandomizers and an output link serializer. [...]
