Abstract

Recent progress with Cadmium Zinc Telluride (CZT) radiation sensors grown by the traveling heater method (THM) at Kromek is reported. Large volume monolithic pixelated detectors, 40×40×15 mm³ have been fabricated with good initial gamma spectroscopy response (< 2.5% energy resolution at 662 keV at room temperature without correction). After depth of interaction (DOI) correction, detector performance with < 1% energy resolution at 662 keV at room temperature has been obtained on pixelated 22×22×15 mm³ CZT detector. For medical imaging applications, 20×20×6 mm³ pixelated detectors exhibits < 3% energy resolution at 122 keV without correction. These results have been achieved via our proprietary THM crystal growth in combination with our robust device fabrication technique. Examples of progress in other areas of CZT development for gamma spectroscopy and imaging applications such as 40×40×5 mm³ cross-strip device for PET and Kromek's general-purpose SPECT camera will also be presented.
