The Department of Homeland Security’s (DHS) Science and Technology (S&T) Directorate is conducting market research related to the further development of Coherent X-Ray Scattering (CXS) or Diffraction (CXD) technology as a reliable for identifying and or detecting explosives in airport luggage. The Request for Information is being issued to ascertain the level of interest and capabilities of private industry to develop prototype systems suitable for laboratory assessment by the government. CXS is a critical element in the broader Manhattan II and Explosives Research programs. DHS expects about one to two years of additional development and integration efforts will be required by industry contractors to deliver to the government prototype systems suitable for laboratory assessment and testing for aviation carry-on and checked baggage screening venues. DHS expects to award selected contractors between $2 million and $3 million each for the purchase of two hardware systems and associated technical information and data. Sol. No. DHSRFI081208.
