GAGG(Ce) Scintillation Crystal
GAGG(Ce) (Ce:GAGG, Gd3Al2Ga3O12) is new scintillator for single photon emission computed tomography(SPECT), gamma-ray and compton electron detection. Cerium doped GAGG have many properties that make it suitable for gamma spectroscopy and medical imaging applications. A high photon yield and emission peak around 520 nm makes the material well suited to be readout by Silicon Photo-multiplier detectors.
Application
1 ) Computed tomography (CT)
2 ) Positron emission tomography (PET)
3 ) Single-photon emission computed tomography (SPECT)
4 ) Particle accelerator
5 ) Laser & LED lighting
Features
1 ) Relatively bright – emitting >50,000 photons/MeV
2 ) Good absorbers with good stopping powers – density 6.63 g/cm³
3 ) Broadly emitting with a 540nm peak
