Detection and Location of Concealed Plastic Explosive in On-line Baggage Screening by Tomographic Interrogation by Neutron Assaying The goal of the project is to develop an innovative system for the location and identification of concealed plastic explosives in on-line screening of checked in baggage in airports, using Tomographic Interrogation by Neutron Assaying. TINA represents an entirely new concept of concealed explosive detection: the combination of a compact, short pulse, high-energy neutron and X-ray source and a new detection methodology based on the assignment and matching of a colour signature to specific groups of chemical elements forming explosives. The system offers 100% detection capability, low false positives, low operator involvement, high throughput and high sensitivity at realistic costs. TINA has a number of innovative features, which are more than merely evolutionary steps.
To validate the technology for an on-line screening system for checked in baggage that can meet today's airport security requirements needs: - to detect explosives of any kind and shape, from a quantity as small as 250g; - to assure a flux in excess of 450 baggage per hour; - 100% detectability that is 0% false negatives; - low false positives (<5% single pass), The objective is to be met in TINA by the development of a technology based on the fusion of four techniques: - pulsed fast neutron analysis (PFNA), - neutron absorption analysis (NAS), - thermal neutron analysis (TNA) and - X-ray imaging, TINA comprises teams from France, UK and Germany, involving technology providers system integrators and end-users. The project provides management and the technology transfer between National bodies, Public utilities and SMEs including NTBF. The performance requirements in baggage screening, in terms of speed, sensitivity and accuracy, are dynamic and subject to legislation and aircraft design. TINA will be developed with the direct involvement of two trans-national airport authorities, together with advice from European air security bodies, to ensure that a demand driven solution would be attained. The successful validation of the technology will open up a unique opportunity for a market worldwide,
