- ItemCharacterization of the demonstrator of the fast silicon monolithic ASIC for the TT-PET project(London : Inst. of Physics, 2019) Paolozzi, L.; Bandi, Y.; Cardarelli, R.; Débieux, S.; Favre, Y.; Ferrère, D.; Forshaw, D.; Hayakawa, D.; Iacobucci, G.; Kaynak, M.; Miucci, A.; Nessi, M.; Ripiccini, E.; Rücker, H.; Valerio, P.; Weber, M.The TT-PET collaboration is developing a small animal TOF-PET scanner based on monolithic silicon pixel sensors in SiGe BiCMOS technology. The demonstrator chip, a small-scale version of the final detector ASIC, consists of a 03 × 1 pixel matrix integrated with the front-end, a 50 ps binning TDC and read out logic. The chip, thinned down to 100 µm and backside metallized, was operated at a voltage of 180 V. The tests on a beam line of minimum ionizing particles show a detection efficiency greater than 99.9% and a time resolution down to 110 ps. © 2019 CERN.
