Portable Inspection System using X-rays for Detection and identification of Explosives and chemical Risks for Security
The discovery of a suspect object in a public domain creates a crisis situation and results in implementing protocols to evaluate the threat and secure the area. The aim of the SPIDERS project is to validate the feasibility of a new enhanced portable inspection system based on complementary X rays techniques. PROJECT => 3 SCIENTIFIC ISSUES + DEMONSTRATOR - 3D & bi energie imaging without mechanical displacement using multiple X ray beams based on carbon nanotube photo-cathodes. - CdZnTe high resolution spectrometric linear detector working at ambient temperature. - 3D diffraction imaging allowing spectral analysis for identifying illegal materials.

– First significant lifetime demonstration of a CNT cathode in a X
ray diode during 3months in continuous operation
– Developpment of a new spectral analysis method based on Energy Dispersive X-Ray Diffraction using a limited database of illegal substances
– A dedicated 3D reconstruction algorithm, based on an iterative
technique implemented within a multi-resolution approach has been developed
