Abstract
The influence of the irradiation of PWO crystals on the characteristic timing parameters of changes in their optical transparency and subsequent recovery during the working cycle of the LHC accelerator (CERN) was studied. PWO crystals were irradiated with a working dose corresponding to the radiation load in the electromagnetic calorimeter. A method for evaluating the influence of the change in the optical transparency of scintillation crystals on the statistical term in the energy resolution of the electromagnetic calorimeter in intense radiation fields is proposed. This method is applied to the development of the technology of mass production of radiation-hard scintillation crystals used in electromagnetic calorimetry and to its certification.
