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. [...]

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.

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.

A new detector capable of measuring the luminosity and beam conditions of the Large Hadron Collider (LHC) is proposed at the interaction point of the LHCb experiment. It will enable real time monitoring of beam parameters, which is of paramount importance in order to safely operate the LHC and its experiments in the beam conditions foreseen for Run 3, starting in 2021, and beyond, towards the High-Luminosity (HL) phase.

The Spaghetti type Calorimeter (SPACAL) with fibers parallel to the beam direction is considered as an option for the inner part of the future LHCb Electromagnetic Calorimeter (ECAL) for the Upgrade Phase 2 [1]. In this work a simulation study of the time measurement precision has been performed for the electron and photon beams with energies of 1, 2, 4, 5 and 10 GeV..
