Crystal Calorimetry in future high-energy physics experiments faces a new challenge to maintain its precision in a hostile radiation environment. This paper discusses the effects of radiation damage in scintillating crystals, and concludes that the predominant radiation damage effect in crystal scintillators is the radiation-induced absorption, or color center formation, not the loss of scintil...

In recent years, the search for new scintillators has renewed, increasing the needs for the development of high-energy physics, nuclear tomography and other fields of science and engineering. For high energy particle accelerators, it is common the use of multiple detectors capable of working under high counting rates, requiring detectors with short decay time (about 10 ns) and high density [3, ...

Measurement of Regional Cerebral Blood Flow With "'Xenon and a MultipleCrystal Scintillation Camera • A method was devised to measure gray and white matter cerebral blood flow simultaneously in multiple regions of the brain using Xenon and a multiple-crystal scintillation camera. Following magnification cerebral arteriography, Xe was injected into the internal carotid artery and the washout of ...

This review article summarizes the recent achievements in stabilization of the metastable lattice of gadolinium aluminate garnet (Gd3Al5O12, GAG) and the related developments of advanced optical materials, including down-conversion phosphors, up-conversion phosphors, transparent ceramics, and single crystals. Whenever possible, the materials are compared with their better known YAG and LuAG cou...

Future colliders will set stringent requirements on the performance of detector materials in terms timing and radiation hardness. Scintillating garnet crystals proved to satisfy latter, while former can be improved through technological developments. In this work, optical scintillation properties Cerium-doped Gd3Al2Ga3O12 (GAGG:Ce) single were studied upon gamma excitation. Several 2x2x3 mm3 2x...

We fabricated (C 6 H 5 C 2 4 NH 3 ) Pb 1- x Sn Br single crystals by the poor-solvent diffusion method and evaluated photoluminescence (PL) scintillation properties. In PL emission maps, exciton-emission peaks were observed at 410 440 nm. The quantum yields of = 0.1, 0.25, 0.5 samples 23.3, 24.1, 19.2% within typical errors (±2%), respectively. spectra under X-ray irradiation, peak was light 59...

Sm-doped SrCl2 crystals were prepared, and the scintillation properties such as emission spectra, decay profiles, pulse height investigated. Under X-ray irradiation, a broad band can be observed at 680 nm, which indicates that major origin is due to 5d-4f transitions of Sm2+. The curve approximated by one exponential function with time 10 ?s, constant typical for From 137Cs ?-rays, 0.1% Sm:SrCl...
