We report on a technology development to address explosive detector system throughout with increased detection probability. The system we proposed and are studying consists of a pixelized X-ray based pre-screener and a pulsed neutron source quantitative post verifier. Both technologies are derived from our compact accelerator development program for the Department of Energy Radiography Mission that enables gradients >10 MV/m. For the pixelized X-ray source panel technology, we have performed initial integration and testing. For the accelerator, we are presently integrating and testing cell modules. For the verifier, we performed MCNP calculations that show good detectability of military and multi-part liquid threat systems. We detail the progress of our overall effort, including research and modeling to date, recent high voltage test results and concept integration.
