Evaluation and Optimization of Explosives Trace Detection Portals

Evaluation and Optimization of Explosives Trace Detection Portals

TSWG participated in a Transportation Security Administration (TSA) study to evaluate and optimize the performance of two explosives trace detection systems, the Smiths Detection Ionscan® Sentinel II and the GE EntryScan3. The TSWG-funded efforts modified these systems to increase detection speed, to detect additional types of explosives, and to improve operational reliability. As a result of this study, TSA has purchased 44 trace detection portals from the two companies. Additional information on the GE EntryScan3 portal is available at http://www.geindustrial.com/ge-interlogix/iontrack/prod_entryscan.html.
