Engineering Overview

YSO(Ce) Scintillation Crystal

YSO(Ce), or cerium-doped yttrium orthosilicate, is a non-hygroscopic scintillation crystal used in X-ray and gamma detection, charged-particle measurement, nuclear physics experiments, and detector research. Because it contains no lutetium, YSO(Ce) does not have the Lu-176 intrinsic activity associated with LYSO(Ce), although total detector background still depends on material purity, packaging, photosensor, electronics, and the operating environment. Typical reference values include a density of about 4.45 g/cm3, an emission peak near 420 nm, and a decay time of approximately 50-70 ns. ATR Crystal supplies custom YSO(Ce) crystals, screens, and array components with dimensions, surface finish, reflector, and readout requirements reviewed according to the detector design.
