     cadmium zinc telluride (czt) detectors are high sensitivity and high resolution devices for hard x-ray imaging and spectroscopic studies. the new series of czt detector modules (oms40g256) manufactured by orbotech medical solutions (oms), israel, are used in the rt-2/czt payload onboard the coronas-photon satellite. the czt detectors, sensitive in the energy range of 20 to 150 kev, are used to image solar flares in hard x-rays. since these modules are essentially manufactured for commercial applications, we have carried out a series of comprehensive tests on these modules so that they can be confidently used in space-borne systems. these tests lead us to select the best three pieces of the ‘gold’ modules for the rt-2/czt payload. this paper presents the characterization of czt modules and the criteria followed for selecting the ones for the rt-2/czt payload. the rt-2/czt payload carries, along with three czt modules, a high spatial resolution cmos detector for high resolution imaging of transient x-ray events. therefore, we discuss the characterization of the cmos detector as well.
