It has of two two layers of Silicon photodiode arrays, targeted for different X-ray energy ranges. X-ray sensitive scintillant material is located on top of the photodiode arrays to convert X-ray signal in to visible light, which generates current at photodiode. The electrical current signals from photodiodes are connected to inputs of charge-sensitive...
