/ Auffray, E (CERN) ; Akchurin, N (Texas Tech.) ; Benaglia, A (CERN) ; Borisevich, A (Minsk, Inst. Nucl. Problems) ; Cowden, C (Texas Tech.) ; Damgov, J (Texas Tech.) ; Dormenev, V (Minsk, Inst. Nucl. Problems) ; Dragoiu, C (Texas Tech.) ; Dudero, P (Texas Tech.) ; Korjik, M (Minsk, Inst. Nucl. Problems) et al.
One of the main challenges for detectors at future high-energy collider experiments is the high precision measurement of hadron and jet energy and momentum. One possibility to achieve this is the dual-readout technique, which allows recording simultaneously scintillation and Cherenkov light in an active medium in order to extract the electromagnetic fraction of the total shower energy on an event- by-event basis.

Picosecond transient absorption rise time for ultrafast tagging of the interaction of ionizing radiation with scintillating crystals in high energy physics experiments
/ Auffray, E (CERN) ; Buganov, O (Minsk, Inst. Phys.) ; Fedorov, A (Minsk, Inst. Nucl. Problems) ; Korjik, M (Minsk, Inst. Nucl. Problems) ; Mechinsky, V (Minsk, Inst. Nucl. Problems) ; Tikhomirov, A (Minsk, Inst. Phys.) ; Vasil'ev, A (SINP, Moscow) ; Lecoq, P (CERN)
Here we report the first results of a search of a signature for picosecond time stamps of the interaction between ionizing particles and transparent crystalline media. The induced absorption with sub-picosecond rise time observed in a cerium fluoride scintillation single crystal under UV excitation is directly associated with the ionization of Ce(3+) atoms in CeF(3) crystals, and the very fast occurrence thereof can be used to generate picosecond-precise time stamps corresponding to the interaction of ionizing particles with the crystal in high energy physics experiments..

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. [...]

This work focuses on the study of changes in the optical transmission of Y 2 SiO 5 :Ce crystals caused by ionizing radiation from γ-quanta and high energy protons. Radioisotope content of proton-irradiated crystals, transmission and induced absorption spectra, and scintillation characteristics are measured after irradiation with protons. [...]

Radiation damage effects in lutetium, yttrium and gadolinium oxy-orthosilicates, Lu_2SiO_5:Ce, Y_2SiO_5:Ce, Gd_2SiO_5:Ce under γ- and protons irradiation have been investigated. Crystals were irradiated with a ^60Co gamma source to a total dose of 2000 Gy and a high-rate 24-GeV proton beam at CERN PS, to a fluence of ~3.6 ×10^13 p/cm^2. [...]

Samples of three heavy crystalline materials: PbWO_4, Bi_4Si_3O_1_2, and PbF_2 were irradiated in a high-intensity 24GeV proton beam at the CERN PS to fluencies of 3.8x10^1^3protons/cm^2. The optical transmission radiation damage was measured and all crystals show a shift of the cutoff in the transmission spectrum that is not observed when the crystals are irradiated with @c radiation.

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

/ 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.
