Abstract
- Fast and heavy inorganic scintillators with suitable radiation tolerance are required to face the challenges presented at future hadron colliders of high energy and intensity. Up to 5 GGy and 5 × 10<superscript>18</superscript> n<subscript>eq</subscript>/cm<superscript>2</superscript> of one-MeV-equivalent neutron fluence is expected by the forward calorimeter at the Future Hadron Circular Collider. This paper reports the results of an investigation of proton- and neutron-induced radiation damage in various fast and heavy inorganic scintillators, such as LYSO:Ce crystals, LuAG:Ce ceramics, and BaF<subscript>2</subscript> crystals. The experiments were carried out at the Blue Room with 800 MeV proton fluence up to 3.0 × 10<superscript>15</superscript> p/cm<superscript>2</superscript> and at the East Port with one MeV equivalent neutron fluence up to 9.2 × 10<superscript>15</superscript> n<subscript>eq</subscript>/cm<superscript>2</superscript>, respectively, at the Los Alamos Neutron Science Center. Experiments were also carried out at the CERN PS-IRRAD proton facility with 24 GeV proton fluence up to 8.2 × 10<superscript>15</superscript> p/cm<superscript>2</superscript>. Research and development will continue to develop LuAG:Ce ceramics and BaF<subscript>2</subscript>:Y crystals with improved optical quality, F/T ratio, and radiation hardness. [ABSTRACT FROM AUTHOR]
