GAGG detector liner array detector highest brightness low afterglow X ray imaging security inspection
Kinheng lanuched the GAGG liner detector for X ray imaging industry, we can process Pitch 0.4, 0.78, 1.575, 2.5mm for liner detector, Usually we offer Liner 1x16 elements array for PD coupling. Our testing show GAGG detector is around 3 times better brightness than CdWO4 detectors. The afterglow performance is same as CdWO4 detectors. This is excellent performance for security inspection industry.

Mechanical design for assembling:
Based on the end use of assembled array, there are many kinds of mechanic design from Kinheng to meet the medical and security inspection industry.
1D Liner array are mainly used for Security inspection industy, such as Bagger scanner, Aviation scanner, 3D scanner and NDT. Material Including CsI(Tl), GOS:Tb/Pr Film, GAGG:Ce, CdWO4 scintillator etc. They are typically coupled with Silicon Photodiode line array for read out.
2D array are normally used for imaging, including Medical(SPECT, PET, PET-CT, ToF-PET), SEM, Gamma camera. These 2D array are typically coupled with SIPM array, PMT array for read out. Kinheng provide 2D array including LYSO, CsI(Tl), LSO, GAGG, YSO, CsI(Na), BGO scintillator etc.
Below is kinheng’s typically design drawing for 1D And 2D array for industry.
