Large size LSO and LYSO crystal scintillators for future high-energy physics and nuclear physics experiments
The high energy and nuclear physics community is interested in fast bright heavy crystal scintillators, such as cerium-doped LSO and LYSO. An investigation is being carried out to explore the potential use of the LSO and LYSO crystals in future physics experiments. Optical and scintillation properties, including longitudinal transmittance, emission and excitation spectra, light output, decay ki...
متن کاملMonitoring LSO/LYSO Crystal Based Calorimeters
Precision light monitoring is important for keeping excellent energy resolution promised by LSO/LYSO crystals in severe radiation environment. In this paper, we report an investigation on the wavelength choice for monitoring LYSO crystal based calorimeters. Gamma-ray induced absorption and light output loss were measured for 20 cm long crystals from five different vendors. Monitoring sensitivit...
متن کاملOxidative membrane damage and its involvement in gamma radiation-induced apoptotic cell death.
Background: Recent results have provided increasing evidence to support involvement of membrane damage in the mechanism of ionizing radiation induced killing of mammalian cells. These findings have stimulated renewed interest in evaluating the damage to membrane as a primary initiator in radiation-induced cell killing especially in apoptotic death. The present study was aimed to gain deeper ins...
متن کاملThe Influence of Crystal Size and Material on Intercrystal Scattering and Parallax in PET Block Detectors: A Monte Carlo Study
Introduction: In this study, we utilized the MCNP4C Monte Carlo code to quantitatively evaluate the influence of crystal size and material on intercrystal scatter and parallax effects. Materials and Methods: For each of the 5 selected crystals (BGO, LSO, LYSO, LuAP, GSO), transport of 511 keV photons originating from a point source and incident on the central cry...
