Cerium doped Gadolinium Aluminium Gallium Garnet - GAGG(Ce)

GAGG(Ce: Gd3Al2Ga3O12) - Cerium doped Gadolinium Aluminium Gallium Garnet, is a relatively new type of single crystal scintillator. It is one of the brightest available scintillators with an emission wavelength of 560nm. In addition to its high performance properties, GAGG(Ce) is also physically rugged which makes it easy to handle and well suited for a broad range of applications.

GAGG(Ce) scintillators have the following features:

High light output
High energy resolution
High density
Rapid decay
No self-radiation
Non-hygroscopic

Typical applications for GAGG(Ce) scintillators include:

CT, PET, and SPECT
Gamma spectroscopy
Compton electron detection
