Engineering Overview
YAG(Ce) Scintillation Crystal
YAG(Ce) (Cerium-doped Yttrium Aluminum Garnet) is a fast, rugged, and non-hygroscopic scintillation crystal renowned for its excellent mechanical properties and chemical stability. With a broad emission band peaking at 550 nm, it offers superb matching with photomultiplier tubes (PMTs) and silicon photodiodes. Thanks to its high resistance to radiation damage and stable performance without the need for protective sealing, YAG(Ce) is widely recognized as an ideal material for electron microscopy (SEM/TEM), X-ray imaging screens, and charged particle detection.
