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.

Irradiation effects on Gd$_{3}$AI$_{3}$Ga$_{3}$O$_{12}$ scintillators prospective for application in harsh irradiation environments / Auffray, E (CERN) ; Dosovitskiy, G (Kurchatov Inst., Moscow) ; Fedorov, A (BSU, Minsk ; Kurchatov Inst., Moscow) ; Guz, I (Kurchatov Inst., Moscow) ; Korjik, M (BSU, Minsk) ; Kratochwill, N (CERN) ; Lucchini, M (Princeton U.) ; Nargelas, S (Vilnius U.) ; Kozlov, D (BSU, Minsk) ; Mechinsky, V (BSU, Minsk ; Kurchatov Inst., Moscow) et al.
We provide evidences that multicomponent garnet-type Ce-doped crystal GAGG (Gd$_{3}$AI$_{3}$Ga$_{3}$O$_{12}$) is a promising scintillator to be applied in harsh irradiation environments, particularly, in high-energy physics experiments and reactor research facilities, where long-term operation is mandatory. Applicability of this scintillator for the upgrade of the detectors at future accelerators with high luminosity like High luminosity LHC is considered and GAGG:Ce with different codopings is compared with Ce-doped oxyorthosilicate crystals, which are currently also strong candidates for such applications.

Multipurpose Ce-doped Ba-Gd silica glass scintillator for radiation measurements / Dormenev, V (U. Giessen, II. Phys. Inst.) ; Amelina, A (Kurchatov Inst., Moscow) ; Auffray, E (CERN) ; Brinkmann, K -T (U. Giessen, II. Phys. Inst.) ; Dosovitskiy, G (Kurchatov Inst., Moscow) ; Cova, F (Milan Bicocca U.) ; Fedorov, A (Kurchatov Inst., Moscow) ; Gundacker, S (CERN) ; Kazlou, D (Belarus State U., Minsk (main)) ; Korjik, M (Kurchatov Inst., Moscow ; Belarus State U., Minsk (main)) et al.
A new inorganic scintillation material based on Ba-Gd silica glass doped with cerium (BGS) is fabricated and studied. With the highest light yield among heavy glasses at the level of 2500 ph/MeV and fast scintillation response, the new scintillator ensures a good coincidence time resolution of < 230 ps FWHM for 511 keV  γ -quanta from a $^{22}$Na source and SiPM readout.

Time and energy resolution with SPACAL type modules made of high-light-yield Ce-doped inorganic scintillation materials: Spillover and background noise effects / Dosovitskiy, G (Kurchatov Inst., Moscow) ; Golutivin, A (Imperial Coll., London ; Natl. U. Sci. Tech., Moscow) ; Guz, I (Serpukhov, IHEP) ; Jacobsson, R (CERN) ; Korzhik, M (Kurchatov Inst., Moscow ; Minsk, Inst. Nucl. Problems) ; Mechinsky, V (Kurchatov Inst., Moscow ; Minsk, Inst. Nucl. Problems) ; Talochka, Y (Minsk, Inst. Nucl. Problems ; Vilnius U.) ; Tamulaitis, G (Vilnius U.) ; Schopper, A (CERN) ; Shmanin, E (Natl. U. Sci. Tech., Moscow)
Performance parameters of a composite detection module of Spaghetti type Calorimeter (SPACAL), which is considered for the inner part of the future LHCb Electromagnetic Calorimeter (ECAL) in Upgrade Phase 2, are simulated using GEANT4 software supported by analytical calculations. The accuracy of the timestamp is estimated in both the front and back sections of the composite detector, whereas the energy resolution is estimated for the total signal from the front and back sections of the detector.

Irradiation studies of a multi-doped Gd$_3$Al$_2$Ga$_3$O$_{12}$ scintillator / Alenkov, V (Unlisted, RU) ; Buzanov, O (Unlisted, RU) ; Dosovitskiy, G (Kurchatov Inst., Moscow) ; Egorychev, V (Moscow, ITEP) ; Fedorov, A (Minsk, Inst. Nucl. Problems) ; Golutvin, A (Natl. U. Sci. Tech., Moscow ; Imperial Coll., London) ; Guz, Yu (Serpukhov, IHEP) ; Jacobsson, R (CERN) ; Korjik, M (Kurchatov Inst., Moscow ; Minsk, Inst. Nucl. Problems) ; Kozlov, D (Minsk, Inst. Nucl. Problems) et al.
The characteristics of a Gd$_3$Al$_2$Ga$_3$O$_{12}$ crystal scintillator doped with cerium and co-doped with magnesium and titanium have been studied, mainly in view of using it for the Phase II upgrade of the LHCb electromagnetic calorimeter. Samples of the scintillator were irradiated with $\gamma$ ($^{60}$Co) to 2 kGy and with 24 GeV protons to 900 kGy. [...]
