Description

YAP(Ce) | Scintillation Crystal is a fast scintillation material with great mechanical resistance and stability.

YAP(Ce) | Scintillation Crystal has excellent physical and chemical properties that ensure that the precision machining and entrance windows can be made with a very thin aluminum layer deposited directly on the entrance surface of the crystal. It also has very low-energy secondary X-ray emissions, making it desirable for imaging applications. Compared with YAG(Ce), YAP(Ce) has higher light yield and a peak emission near 370 nm, which is well matched with S11 photomultipliers’ maximum sensitivity.
