Design and experiment of dual-energy X-ray material recognition using a 950keV X-band Linac

摘要

The 950 keV portable X-band (9.4 GHz) linear accelerator (Linac) provides on-site high-energy X-ray inspection, including material recognition up to a certain precision. We have developed an X-band Linac system and have achieved the maximum 950keV X-ray by using the low-power magnetron (250 kW) in a 2-μs pulse length. We have already experimentally verified the dual-energy X-ray material recognition with and without an energy filter. Further, the array of the scintillator detector for dual-energy X-ray measurement without the energy filter is numerically analyzed and designed for much quicker measurements. Updated results will be presented.
