초록

Composite scintillation screens on a base of Gd1.2Y1.8Ga2.5Al2.5O12:Ce (GYAGG) scintillator have beenevaluated for neutron detection. Besides the powdered scintillator, the composite includes 6LiF particles;both are merged with a binder and deposited onto the light-reflecting aluminum substrate. Resultsobtained demonstrates that screens are suitable for use with a silicon photomultiplier readout to create aprospective solution for a compact and low-cost thermal neutron sensor. Composite GYAGG/6LiF scintillationscreen shows a pretty matched sensitivity and g-background rejection with a widely usedZnS/6LiF screens however, possesses forty times faster response.
