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 540 nm makes the material well suited to be readout by Silicon Photo-multiplier detectors.


Epic crystal developed 4 kinds of GAGG(Ce) crystal, with faster decay time(GAGG-F), typical(GAGG-T), higher light output(GAGG-HL) and higher energy resolution(GAGG-HR) crystal, for the customer in different field.


GAGG(ce) is a very promising scintillator in high energy industrial field, when it was characterized on life test under 115kv, 3mA and the radiation source located at a 150 mm distance from crystal, after 20 hours the performance is nearly the same as the fresh one. It means it has a good prospect to withstand high dose under X-ray irradiation, of course it depends on irradiation conditions and in case of going further with GAGG for NDT further exact test need to be conducted. 

 

Beside the single Ce: GAGG crystal, we are able to fabricate it into linear and 2 dimensional array, the pixel size and separator could be achieved based on requirement. We also have developed the technology for the ceramic Ce:GAGG, it has better coincidence resolving time(CRT), faster decay time and higher light output.
