Physics:GAGG:Ce

From HandWiki

Cerium-doped gadolinium aluminium gallium garnet (GAGG:Ce) is a single-crystal scintillator material (can also be used as ceramic poly-crystal scintillator).[1][2] It is being considered for applications in astrophysics, such as in high-energy gamma ray detection.[3]

The Gamma-ray Transients Monitor (a space telescope), which tracks Gamma Ray Bursts (GRBs) and other bright gamma-ray transients with energies ranging from 50 keV to 2 MeV uses GAGG scintillator array (50 mm x 50 mm x 8 mm) as its sensor units.[4]
