Yttrium aluminum doping cerium is a fast, mechanically strong and chemically resistant scintillation material. Mechanical properties enable precise machining and entrance windows can be made with a very thin aluminum layer deposited directly on the entrance surface of the crystal. YAP:Ce scintillators have very low energy secondary X-ray emissions which makes them desirable for imagining applications. YAP:Ce detectors are used for gamma and X-ray counting, electron microscopy, electron and X-ray imaging screens, and tomography systems.
