Paper Abstract

TlBr based photon-counting imaging device has been developed by using our photon-charge counting ASIC. TlBr of 0.8mm-thick wafer was used for detector, and it was pixelized as 80um pitch pixel. Tl based electrode was deposited on TlBr surface as common electrode and Ag electrodes were used as pixelized electrode. The ASIC has 32 x 32 pixels with 80um pitch, 16 thresholds, upto 250kcps of count rate by fully digital processing. This ASIC treat generated charge by detector directly, it can be applied CdTe, TlBr and so on. We detected X-ray / gamma-ray signals. We demonstrate X-ray / gamma-ray images taken by this device and discuss with energy discrimination property and so on.
