Abstract
To allow for fast, automated inspection of checked baggage with low false alarm rates, we designed and built a novel X-ray diffraction (XRD) system to use in a hybrid CT+XRD configuration, where each bag is scanned by both CT and XRD systems. Our XRD system is modular, vendor agnostic, and operates inline with the CT system at belt speed with full-tunnel coverage. In this work, we demonstrate reduced false alarm rates (relative to CT alone) with our XRD system placed inline and integrated mechanically and via software with a Smiths CTX 5800 (a certified EDS system) for fully-automated material-based alarm decisions.
