IN ADDITION TO ITS PRIMARY MISSION OF ENSURING TRANSPORTATION SECURITY, TSA DESIRES TO IMPROVE THE OVERALL PASSENGER EXPERIENCE AS WELL AS TSA%U2019S OPERATING EFFICIENCY. ONE OF THE WAYS TSA CAN ACHIEVE THIS IS THROUGH DEVELOPMENT AND TESTING OF MORE SENSITIVE EXPLOSIVE TRACE DETECTION (ETD) SYSTEMS AND SUPPORTING SAMPLING EQUIPMENT. A LIGHT-WEIGHT, HIGH-VOLUME, NON-CONTACT HAND-HELD SAMPLING EQUIPMENT TO TRACE EXPLOSIVES WOULD PROVIDE ADVANTAGES TO TSA WHEN IT IS HARD TO COLLECT SAMPLE FROM THE OBJECT EITHER DUE TO COMPLEX GEOMETRIC OUTLINES OR VARIED SURFACES. THE FOLLOWING TASKS ARE CONSIDERED FOR THIS SOW: 1) MODIFICATION OF AN EXISTING NON-CONTACT SURFACE SAMPLER TO INTERFACE WITH SMITHS 500DT COLLECTION COUPON HOLDER, 2) LABORATORY TESTING OF THE COMBINED COLLECTION/DETECTION SYSTEM USING WITH RELEVANT TARGETS AND SURFACE SUBSTRATES, 3) FIELD TESTING OF THE COMBINED COLLECTION/DETECTION SYSTEM, AND 4) SUPPORT OF TESTING THE COMPLETE SYSTEM AT A GOVERNMENT FACILITY.
