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, composite includes 6LiF particles; both are merged with binder and deposited onto light-reflecting aluminum substrate. Results obtained demonstrates that suitable use silicon photomultiplier readout to create prospective solution compact low-cost thermal sensor. GYAGG/6LiF screen shows pretty matched sensitivity γ-background rejection widely used ZnS/6LiF however, possesses forty times faster response.
