Description
Yttrium aluminum perovskite activated by cerium is a fast(28 ns decay time), mechanically and chemically resistant scintillation material. These scintillators have very low energy secondary X-ray emission, which is of advantage in imaging applications. YAP:Ce detectors are used for gamma and X-ray counting, electron microscopy, electron and X-ray imaging screens. The materials scintillation and mechanical properties enable their use in tomography systems.
