Engineering Overview
LuAG(Ce) Scintillation Crystal
LuAG(Ce), or cerium-doped lutetium aluminum garnet, is a dense, non-hygroscopic garnet scintillator used in electron microscopy screens, X-ray imaging, and compact radiation detector systems. Typical reference values include a density of about 6.73 g/cm3, an emission peak near 535 nm, and a decay time around 70 ns. Its green emission can be matched with photodiodes, avalanche photodiodes, and suitable imaging sensors after the spectral response and optical coupling are reviewed. Final detector performance depends on crystal thickness, cerium concentration, surface finish, optical coupling, photosensor, and test conditions. ATR Crystal supplies custom LuAG(Ce) crystals and thin scintillation screens according to drawing and application requirements.
