High density ruggedness and radiation hardness Matrix BGO scintillator Array
BGO (Bi4Ge3O12) is a scintillation crystal used for gamma ray detection with a high effective atomic number and density.It is the most widely used oxide-based scintillator owing to its many strengths, including high density, ruggedness, and radiation hardness.
BGO has an emission peak of 480 nm, coupling well with PMT and SiPM. Compared to other scintillation crystals, BGO has an unparalleled absorption rate at photopeak. Its energy resolution is about 12%. The scintillation characteristics of BGO changes linearly with temperature.

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 linear 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.
