Radiation resistance and fluorescence of europium doped BGO crystals
We report on a study of the radiation resistance and fluorescence of bismuth germanate scintillation crystals doped with europium (BGO : Eu). The transmission spectrum, the light output and the fluorescence spectrum of BGO : Eu crystals were measured before and after irradiation . The radiation resistance of BGO : Eu crystals was found to be increased with increase of europium doping. A red flu...
متن کاملA study on radiation damage in doped BGO crystals
We report on a study of the correlation between radiation damage of bismuth germanate (BGO) scmtillator crystals and trace impunties in the crystal . The light yield and the absorption spectra of doped BGO crystals were measured, both before and after irradiation . While trace concentrations of Cr, Mn, Fe and Pb m BGO were found to lead to substantial radiation damage, traces of Al, Ca, Cu and ...
متن کاملA Study on Radiation Damage in BGO and PWO-II Crystals
We report in this paper an investigation on radiation damage in 20 cm long BGO crystals produced at SIC as well as 20 cm long PWO-II crystals produced at BTCP for the proposed Panda experiment at GSI. The optical and scintillation properties of BGO and PWOII crystals, such as transmittance, light output and light response uniformity, were measured before and after γ-ray irradiations at differen...
متن کاملRadiation hardness qualification of PbWO4 scintillation crystals for the CMS Electromagnetic Calorimeter
Ensuring the radiation hardness of PbWO4 crystals was one of the main priorities during the construction of the electromagnetic calorimeter of the CMS experiment at CERN. The production on an industrial scale of radiation hard crystals and their certification over a period of several years represented a difficult challenge both for CMS and for the crystal suppliers. The present article reviews ...
متن کاملRadiation hardness of SiPM in the PANDA radiation environment
Silicon photomultipliers (SiPM) consist of a pixelized array of micrometric avalanche photodiodes (APD) connected in parallel. Their small size and low voltage operation allows the construction of very compact detectors. The price to pay is the megahertz dark count rate at room temperature. These events are generated by thermal electrons within the pixel and are undistinguishable from real sign...
