Composite scintillation screens on a base of Gd1.2Y1.8Ga2.5Al2.5O12:Ce (GYAGG) scintillator have been evaluated 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. Results obtained demonstrates that screens are suitable for use with a silicon photomultiplier readout to create a prospective solution for a compact and low-cost thermal neutron sensor. Composite GYAGG/6LiF scintillation screen shows a pretty matched sensitivity and γ-background rejection with a widely used ZnS/6LiF screens however, possesses forty times faster response.
