Proton-Induced Radiation Damage in BaF_2, LYSO and PWO Crystal Scintillators


Future high energy physics experiments at the energy and intensity frontiers will face a challenge of severe radiation environment from both ionization dose and charged and neutral hadrons. The high luminosity large hadron collider, for example, will present an environment, where up to 130 Mrad ionization dose, 3×10^(14) charged hadrons/cm^2 and 5×10^(15) neutrons/cm^2 are expected. In this paper, we report our investigation on charged hadron induced radiation damage in BaF_2, LYSO/LFS and PWO crystals up to 3×10^(15) protons/cm^2 by using 800 MeV protons at the Los Alamos Neutron Science Center. Comparison is made between radiation damages induced by protons and ionization dose alone.
