Proton-Induced Radiation Damage in BaF2, 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 ioni...

Description
Summary: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 \times 10^{14} charged hadrons/cm 2 and 5 \times 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 \times 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.
