Cerium-doped gadolinium aluminium gallium garnet (Ce:GAGG) is a relatively new single crystal scintillator with several interesting properties, such as very high light yield, high density, good energy resolution, an emission peak well-matched to silicon sensors, and low intrinsic energy resolution. Moreover, the material is nonhygroscopic and non-selfradiation. It will be widely used in PET, PEM, SPECT, CT, X-ray &Gamma ray detection.
Features
Relatively bright emitting >50,000 photons/MeV
Good absorbers with good stopping powers - density 6.63 g/cm
Broadly emitting with a 540nm peak
Good Energy resolution
Application
CT
PET
SPECT
LED lighting
Laser lighting
Particle accelerator
