Dia1.5mm Ce:GAGG Scintilation Single Crystal Rod
Ce: GAGG crystal (chemical formula Ce: Gd3Al2Ga3O12, also known as cerium-doped gadolinium aluminum gallium garnet crystal) is a scintillation crystal with excellent comprehensive performance, which is widely used in scientific research and industrial high-energy ray detection. Ce: The effective atomic number of the GAGG crystal is as high as 54.4, and the peak wavelength of the emission spectrum located at 520nm, which matches well with the sensitive wavelength range of the photomultiplier tube (PMT) and silicon photodiode (PD).
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.
