Abstract (en)

[origin: WO2016083766A1] A backscatter imaging apparatus (10), comprises a laser plasma (wakefield) accelerator (2) directing a short pulsed, collimated beam of electrons (3) towards a barrier (4) and a concealed object (5). A fast detector (6) receives a backscattered X-ray signal (7) and generates an electronic signal representative of the intensity of X-rays backscattered by each scattering event. Signal processor (8) analyses the signal intensity and time domain data to determine the range of the scattering event from the apparatus. The imaging device (9) displays an output image of the spatially resolved density profile of the object (5) concealed behind a barrier (4). The use of a laser wakefield generated electron beam allows X-ray backscatter imaging across an increased stand-off range or greater penetrative depth.
