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.

Time of flight (TOF) in positron emission tomography (PET) has experienced a revival of interest after its first introduction in the eighties. This is due to a significant progress in solid state photodetectors (SiPMs) and newly developed scintillators (LSO and its derivatives). [...]

High-frequency SiPM readout advances measured coincidence time resolution limits in TOF-PET / Gundacker, Stefan (Milan Bicocca U. ; CERN) ; Turtos, Rosana Martinez (CERN) ; Auffray, Etiennette (CERN) ; Paganoni, Marco (Milan Bicocca U.) ; Lecoq, Paul (CERN)
Scintillator based radiation detectors readout by SiPMs successively break records in their reached time resolution. Nevertheless, new challenges in time of flight positron emission tomography (TOF-PET) and high energy physics are setting unmatched goals in the 10 ps range. [...]

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. [...]

Timing capabilities of garnet crystals for detection of high energy charged particles / Lucchini, M T (CERN) ; Gundacker, S (CERN) ; Lecoq, P (CERN) ; Benaglia, A (Princeton U.) ; Nikl, M (Prague, Inst. Phys.) ; Kamada, K (Tohoku U. ; Unlisted, JP) ; Yoshikawa, A (Tohoku U. ; Tohoku U., Inst. Materials Res. ; Unlisted, JP) ; Auffray, E (CERN)
Particle detectors at future collider experiments will operate at high collision rates and thus will have to face high pile up and a harsh radiation environment. Precision timing capabilities can help in the reconstruction of physics events by mitigating pile up effects. [...]

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).

Precision Timing in the CMS MTD Barrel Timing Layer with Crystal Bars and SiPMs / Santanastasio, Francesco (INFN, Rome ; Rome U.) /CMS Collaboration
The Compact Muon Solenoid (CMS) detector at the CERN Large Hadron Collider (LHC) is undergoing an extensive Phase II upgrade program to prepare for the challenging conditions of the High-Luminosity LHC (HL-LHC). In particular, a new timing layer will measure minimum ionizing particles (MIPs) with a time resolution of 30-40 ps and hermetic coverage up to a pseudo-rapidity of 3. [...]
