/ Lucchini, M T ; Buganov, O ; Auffray, E (CERN) ; Bohacek, P ; Korjik, M ; Kozlov, D ; Nargelas, S ; Nikl, M ; Tikhomirov, S ; Tamulaitis, G et al.
Non-linear absorption spectroscopy in pump and probe configuration has been used to test the population of non-equilibrium carriers in Ce-doped Y$_{3}$Al$_{5}$O_${12}$ (YAG), Lu3Al5O12 (LuAG), and Gd3AlxGa(5-x)O12 (GAGG) crystals with and without codoping by Mg2+ ions. A faster rise time of the induced optical density has been observed in all crystals codoped with Mg with respect to that in Mg-free samples. [...]

/ Kononets, V (Inst. Scintill. Mat., Kharkiv ; ILM, Lyon) ; Auffray, E (CERN) ; Dujardin, C (ILM, Lyon) ; Gridin, S (Inst. Scintill. Mat., Kharkiv) ; Moretti, F (ILM, Lyon) ; Patton, G (ILM, Lyon) ; Pauwels, K (CERN) ; Sidletskiy, O (Inst. Scintill. Mat., Kharkiv) ; Xu, X (Xuzhou Normal U.) ; Lebbou, K (ILM, Lyon)
Undoped and Ce3+-doped Lu3Al5O12 (LuAG) fibers were grown to evaluate their potential use in new particle physics experiments, such as dual-readout calorimeters. The choice of grown crystals was made to detect scintillation (doped LuAG) and Cherenkov radiation (undoped LuAG). [...]

Undoped and Ce-doped $Lu_3Al_5O_{12}$ (LuAG) and $Y_3Al_5O_{12}$ (YAG) single crystal fibers were grown by the micro-pulling down technique (μ-PD) with a purpose to fit the design of new dual-readout calorimeter planned to operate in future experiences of high energy physics. Fibers up to 20 cm in length and 1 mm in diameter were grown along [111] direction. [...]

The aim of this work has been to improve the time resolution of radiation detectors for future high-energy physics experiments and medical imaging applications. Cedoped oxyorthosilicate Lu$_2$SiO$_5$:Ce (LSO) and mixed oxyorthosilicate Lu$_{1.6}$Y$_{0.4}$SiO$_5$:Ce (LYSO) have been investigated as prospective scintillators for such high-timeresolution applications.

Timing capabilities of garnet crystals for detection of high energy charged particles

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. [...]

We summarize the latest R&D; state-of-art of Ce 3+ and Pr 3+ -doped mixed (Lu x Y 1-x ) 3 Al 5 O 12 (LuYAG) garnet scintillator crystals and compare their properties with those of Lu 3 Al 5 O 12 (LuAG) and Y 3 Al 5 O 12 (YAG) single crystal analogues. Light yield, energy resolution and proportionality were studied under radioisotope excitation within 8-1300 keV energy range. [...]

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. [...]
