A 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 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 کاملRadiation Damage Kinetics in Pwo Crystals
This note proposed a model to describe the kinetics of the irradiation damage in PWO crystal and apply it to two well-known measurement methods of the optical transmission damaged by irradiation. 1 . Introduction It is known that in some PWO crystals damage to their optical properties appears under ionizing radiation. A decrease of the optical transmission and then of light yield has been detec...
متن کاملRadiation 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 rate making and required reserves determination in reinsurance market: a simulation
reinsurance is widely recognized as an important instrument in the capital management of an insurance company as well as its risk management tool. this thesis is intended to determine premium rates for different types of reinsurance policies. also, given the fact that the reinsurance coverage of every company depends upon its reserves, so different types of reserves and the method of their calc...
