Abstract

Energy dispersive x-ray diffraction (EDXRD) is a promising technique in security screening. The study focuses on the collimators optimization to achieve the highest system sensitivity under certain spatial and angular resolution requirements. The effects of system parameters on the resolution have been studied using an efficient and simple simulation method. The angular resolution requirements play the major limiting role when the length of the collimator is small, while the spatial resolution limit the sensitivity and the angular resolution requirements are automatically satisfied with the increasing of the collimator’s length. Several other suggestions on the EDXRD system designs are also proposed.
