Improving light output and coincidence time resolution of scintillating crystals using nanoimprinted photonic crystal slabs
/ Pots, Rosalinde Hendrika (CERN ; RWTH Aachen U.) ; Salomoni, Matteo (CERN ; Milan Bicocca U.) ; Gundacker, Stefan (CERN ; Milan Bicocca U.) ; Zanettini, Silvia (Silsef, Archamps) ; Gâté, Valentin (Silsef, Archamps ; Napa Technologies, Archamps) ; Usureau, Elise (Napa Technologies, Archamps) ; Turover, Daniel (Silsef, Archamps ; Napa Technologies, Archamps) ; Lecoq, Paul (CERN) ; Auffray, Etiennette (CERN)
Scintillating crystals are used in numerous applications of ionizing radiation detectors. In time of flight positron emission tomography (TOF-PET) for example, both energy and coincidence time resolution (CTR) are important characteristics that could significantly benefit if more light from scintillators, otherwise trapped, could be collected by the photodetector.

Timing performance of lead halide perovskite nanoscintillators embedded in a polystyrene matrix
/ Děcká, Kateřina (Prague, Tech. U. ; Prague, Inst. Phys.) ; Pagano, Fiammetta (CERN ; Milan Bicocca U.) ; Frank, Isabel (CERN ; LMU Munich (main)) ; Kratochwil, Nicolaus (CERN) ; Mihóková, Eva (Prague, Tech. U. ; Prague, Inst. Phys.) ; Auffray, Etiennette (CERN) ; Čuba, Václav (Prague, Tech. U.)
Nanomaterials like CsPbBr3, benefiting from quantum confinement effects to feature ultra-fast decay time and tunable emission, are paving the way for the next generation of fast timing detectors. However, an ongoing challenge is to exploit their favorable properties in a full detector, given their size and instability. [...]

Vacuum ultraviolet silicon photomultipliers applied to BaF2 cross-luminescence detection for high-rate ultrafast timing applications

Inorganic scintillators are widely used for fast timing applications in high-energy physics (HEP) experiments, time-of-flight positron emission tomography and time tagging of soft and hard x-ray photons at advanced light sources. As the best coincidence time resolution (CTR) achievable is proportional to the square root of the scintillation decay time it is worth studying fast cross-luminescence, for example in BaF2 which has an intrinsic yield of about 1400 photons/MeV.

Compositional engineering of multicomponent garnet scintillators: towards an ultra-accelerated scintillation response
/ Martinazzoli, Loris (CERN ; Milan Bicocca U. ; INFN, Milan Bicocca) ; Nargelas, Saulius (Vilnius, Inst. Theor. Phys. Astron.) ; Boháček, Pavel (Prague, Inst. Phys.) ; Calá, Roberto (CERN ; Milan Bicocca U. ; INFN, Milan Bicocca) ; Dušek, Michal (Prague, Inst. Phys.) ; Rohlíček, Jan (Prague, Inst. Phys.) ; Tamulaitis, Gintautas (Vilnius, Inst. Theor. Phys. Astron.) ; Auffray, Etiennette (CERN) ; Nikl, Martin (Prague, Inst. Phys.)
Optical, luminescence and scintillation characteristics were studied in garnet-type GAGG single-crystal scintillators grown by the Czochralski method and heavily doped with a cerium activator and a magnesium codopant at different concentrations. Emission quenching due to the formation of closely spaced Ce–Mg pairs accelerating the photoluminescence and scintillation decays down to a few nanoseconds and substantial suppression of slower decay components are observed.
