摘要：

Response function measurement of Gd2Si2O7 (GPS) scintillator for thermal neutrons was carried out. GPS single crystals exhibits light output twice higher than GSO single crystals for thermal neutrons. In addition, similar experiments with GPS scintillators of 50 pm in thickness were conducted to improve signal-to-noise ratio between neutrons and gamma-ray. GPS powder samples, size of each particle was 50 pro, showed lower light output than that of GPS single crystals, because absorption and scattering of scintillation light at the sample surface reduced the correction efficiency of scintillation fight. Optimization of the particle size, reflectors and techniques to fix the GPS sample will improve the powder density and detection efficiency because powder samples were directly coated on a glass plate in this experiment.
