抄録

Gadolinium pyrosilicate (Gd2Si2O7, GPS:Ce) scintillators with various cerium concentrations were synthesized using a Top Seeded Solution Growth (TSSG) method. Scintillation properties for 5.5 MeV alpha particles from 241Am are investigated as a part of development of alpha-particle dust monitor for nuclear reprocessing facilities. Polycrystalline GPS with cerium concentrations of 1.0, 2.5, 10% were fabricated. Orthorhombic GPS with l-2.5% of cerium has light output 3.5-3.9 times greater than GSO. The triclinic GPS with 10% of cerium is inferior to the orthorhombic GPS in light output. For GPS with 2.5% of cerium, annealing in N2 atmosphere shows significant improvement in energy resolution.
