Abstract: An X-ray based inspection systems providing radiographic imaging for cargo inspection and material discrimination with adaptive control dependent upon characteristics of the cargo under inspection. A packet of X-ray pulses with controllable packet duration is produced that allows multi-energy material discrimination in a single scan line and real-time adjustment of packet duration to adapt to cargo attenuation. In addition, adaptive dynamic adjustment of the operational characteristic of the detector channels increases the effective dynamic range and as a result increases the penetration and range of thicknesses where material discrimination is possible. The material discrimination technique is applied within a single packet of short pulses of several hundred nanoseconds. Feedback from the detection system is used to control the packet duration of each packet of X-ray pulses in order to adapt scan parameters to the object that is being imaged.

Abstract: A tapering enhanced stimulated superradiant amplification method and system which utilizes a strongly tapered undulator in reaching significant power outputs and conversion efficiencies. TESSA dramatically increases conversion/amplification efficiencies by violently (sharply) decelerating electrons and taking advantage of produced radiation to further drive interaction toward as it takes advantage of produced radiation to further drive interaction to increase overall radiation output. The system and method configures a strongly tapered undulator to operate in a new mode that is above normal input saturation levels to provide an amplified output with unexpectedly high efficiencies and power.
