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. [...]

/ 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

Transient Phenomena in Scintillation Materials
/ Tamulaitis, G (Vilnius U.) ; Nargelas, S (Vilnius U.) ; Vaitkevičius, A (Vilnius U.) ; Lucchini, M (CERN) ; Auffray, E (CERN) ; Fedorov, A (Belarus State U.) ; Mechinsky, V (Belarus State U.) ; Korjik, M (Belarus State U.)
Time resolution becomes an increasingly important property of the scintillators to be exploited in radiation detectors for coming high-luminosity high-energy physics experiments and medical imaging applications. Multicomponent scintillators enable purposeful design of scintillation properties and, consequently, are attractive for fast radiation detection but suffer for the emission delay due to trapping of nonequilibrium carriers.

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. [...]

Subpicosecond luminescence rise time in magnesium codoped GAGG:Ce scintillator

The influence of co-doping of Gd$_{3}$Al$_{2}$GA$_{3}$O$_{12}$:Ce (GAGG:Ce) scintillator with magnesium on the rise time of luminescence response was studied in two GAGG:Ce crystals grown in nominally identical conditions except of Mg co-doping in one of them. Time-resolved photoluminescence spectroscopy and free carrier absorption techniques were exploited. [...]

Optical transmission damage of undoped and Ce doped $Y_3Al_5O_{12}$ scintillation crystals under 24 GeV protons high fluence
/ Auffray, E (CERN) ; Fedorov, A (Minsk, Inst. Nucl. Problems) ; Dormenev, V (Giessen U.) ; Houžvička, J (COMPAS, Turnov) ; Korjik, M (Minsk, Inst. Nucl. Problems) ; Lucchini, M T (CERN) ; Mechinsky, V (Minsk, Inst. Nucl. Problems) ; Ochesanu, S (COMPAS, Turnov)
This report presents results on the optical transmission damage of undoped and Ce doped $Y_3Al_5O_{12}$ scintillation crystals under high fluence of 24 GeV protons. We observed that, similarly to other middle heavy scintillators, it possesses the unique radiation hardness at fluence values as high as $5×10^{14} p/cm^2$ and it is thus promising for the application in the detectors at High Luminosity LHC.

Beam test evaluation of electromagnetic calorimeter modules made from proton-damaged PbWO$_4$ crystals
/ Adams, T (Florida State U., Tallahassee (main)) ; Adzic, P (Belgrade U.) ; Ahuja, S (Sao Paulo, IFT) ; Anderson, D (Caltech) ; Andrews, M B (Carnegie Mellon U.) ; Antropov, I (Ecole Polytechnique) ; Antunovic, Z (Split U.) ; Arcidiacono, R (INFN, Turin ; Moscow, ITEP) ; Arenton, M W (Virginia U.) ; Argiro, S (INFN, Turin ; Moscow, ITEP) et al.
The performance of electromagnetic calorimeter modules made of proton-irradiated PbWO(4) crystals has been studied in beam tests. The modules, similar to those used in the Endcaps of the CMS electromagnetic calorimeter (ECAL), were formed from 5×5 matrices of PbWO(4) crystals, which had previously been exposed to 24 GeV protons up to integrated fluences between 2.1× 10(13) and 1.3× 10(14) cm(−)(2).

Non-Linear Optical Phenomena in Detecting Materials as a Possibility for Fast Timing in Detectors of Ionizing Radiation
/ Korjik, M. V. (Minsk, Inst. Nucl. Problems) ; Auffray, E. (CERN) ; Buganov, O. (Minsk, Inst. Phys.) ; Fedorov, A. A. (Minsk, Inst. Nucl. Problems) ; Emelianchik, I. (Minsk, Inst. Nucl.

The time resolution of the detectors currently in use is limited by 50-70 ps due to the spontaneous processes involved in the development of the response signal, which forms after the relaxation of carriers generated during the interaction. In this study, we investigate the feasibility of exploiting sub-picosecond phenomena occurring after the interaction of scintillator material with ionizing radiation by probing the material with ultra-short laser pulses.

Application of two-photon absorption in PWO scintillator for fast timing of interaction with ionizing radiation
/ Auffray, E (CERN) ; Buganov, O (Minsk, Inst. Phys.) ; Korjik, M (Minsk, Inst. Nucl. Problems) ; Fedorov, A (Minsk, Inst. Nucl. Problems) ; Nargelas, S (Vilnius U.) ; Tamulaitis, G (Vilnius U.) ; Tikhomirov, S (Minsk, Inst. Phys.) ; Vaitkevičius, A (Vilnius U.)
This work was aimed at searching for fast phenomena in scintillators in sub-10-ps range, a benchmark timing for the time response of radiation detectors in particle colliders. The pump-and-probe optical absorption technique with a tunable-wavelength parametric oscillator as the pump and a continuous-spectrum source as the probe beam was used to study lead tungstate PbWO 4 (PWO) single crystals.
