Neutron and Proton-Induced Radiation Damage in LuAG Scintillating Ceramics

Abstract

Because of its potential low cost, bright and fast LuAG scintillating ceramics have attracted a broad interest in the HEP community. One crucial issue for its application at future high energy colliders is its radiation hardness against hadrons, including both neutrons and protons. LuAG ceramics were irradiated at LANSCE and CERN up to 6.7×1015neq/cm2 and 1.2×1015 p/cm2 respectively, and are found to have a factor of two better radiation hardness than LYSO crystals. Ca2+ codoping in LuAG ceramics improves the fast to total ratio and the radiation hardness against hadrons.
