Abstract
We are currently investigating the spatial resolution of highly pixelated Cadmium Zinc Telluride (CZT) detector for imaging applications. A 20 mm {\times} 20 mm {\times} 5 mm CZT substrate was fabricated with 600 {\mu}m pitch pixels (500 {\mu}m anode pixels with 100 {\mu}m gap) and coplanar cathode. Charge sharing between two pixels was studied using collimated 122 keV gamma ray source. Experiments show a resolution of 125 {\mu}m FWHM for double-pixel charge sharing events when the 600 {\mu}m pixelated and 5 mm thick CZT detector biased at -1000 V. In addition, we analyzed the energy response of the 600 {\mu}m pitch pixelated CZT detector.
