Sub-100 ps coincidence time resolution for positron emission tomography with LSO:Ce codoped with Ca / Nemallapudi, Mythra Varun (CERN) ; Gundacker, Stefan (CERN) ; Lecoq, Paul (CERN) ; Auffray, Etiennette (CERN) ; Ferri, Alessandro (Fond. Bruno Kessler, Trento) ; Gola, Alberto (Fond. Bruno Kessler, Trento) ; Piemonte, Claudio (Fond. Bruno Kessler, Trento)
The coincidence time resolution (CTR) becomes a key parameter of 511keV gamma detection in time of flight positron emission tomography (TOF-PET). This is because additional information obtained through timing leads to a better noise suppression and therefore a better signal to noise ratio in the reconstructed image. [...]

Experimental time resolution limits of modern SiPMs and TOF-PET detectors exploring different scintillators and Cherenkov emission / Gundacker, Stefan (Milan Bicocca U. ; CERN) ; Martinez Turtos, Rosana (CERN) ; Kratochwil, Nicolaus (CERN ; Vienna U.) ; Pots, Rosalinde Hendrika (CERN ; RWTH Aachen U.) ; Paganoni, Marco (Milan Bicocca U. ; CERN) ; Lecoq, Paul (CERN) ; Auffray, Etiennette (CERN)
Solid state photodetectors like silicon photomultipliers (SiPMs) are playing an important role in several fields of medical imaging, life sciences and high energy physics. They are able to sense optical photons with a single photon detection time precision below 100 ps, making them ideal candidates to read the photons generated by fast scintillators in time of flight positron emission tomography (TOF-PET).

Detection of high energy muons with sub-20 ps timing resolution using L(Y)SO crystals and SiPM readout / Benaglia, A (CERN) ; Gundacker, S (CERN) ; Lecoq, P (CERN) ; Lucchini, M T (CERN) ; Para, A (Fermilab) ; Pauwels, K (CERN) ; Auffray, E (CERN)
Precise timing capability will be a key aspect of particle detectors at future high energy colliders, as the time information can help in the reconstruction of physics events at the high collision rate expected there. Other than being used in detectors for PET, fast scintillating crystals coupled to compact Silicon Photomultipliers (SiPMs) constitute a versatile system that can be exploited to realize an ad-hoc timing device to be hosted in a larger high energy physics detector.

Measurement of intrinsic rise times for various L(Y)SO and LuAG scintillators with a general study of prompt photons to achieve 10 ps in TOF-PET / Gundacker, Stefan (CERN) ; Auffray, Etiennette (CERN) ; Pauwels, Kristof (CERN) ; Lecoq, Paul (CERN)
The coincidence time resolution (CTR) of scintillator based detectors commonly used in positron emission tomography is well known to be dependent on the scintillation decay time (${{\tau}_{d}}$ ) and the number of photons detected (${{n}^{\prime}}$ ), i.e. $CTR\propto \sqrt{{{\tau}_{d}}/{{n}^{\prime}}}$ .
