摘要：

We have developed a novel detector device, namely: a mercuric iodide photodetector array (HgI2 PDA) to be used with a scintillating crystal for X-ray and gamma-ray imaging. A HgI2 PDA prototype with 16-pixels has been evaluated with segmented scintillators (CsI(TI)) coupled to the HgI2 PDA. Pixel energy resolution of 9.4% FWHM has been obtained at 122 keV for a 4 mm thick scintillator corresponding to 72% stopping at 140 keV, and pixel energy resolution of 11% FWHM has been obtained at 122 keV with the 10 mm thick scintillator.
