AB - Lawrence Livermore National Lab (LLNL) is building an intense, high-brightness fast neutron source to create millimeter-scale neutron radiographs and images. An intense source (10¹¹ n/s/sr at 0 degrees) of fast neutrons (10 MeV) allows for penetrating very thick, dense objects while preserving the ability to create good image contrast in low density features within the object and maintaining high detector response efficiency. Fast neutrons will be produced using a pulsed 7 MeV, 300 microamp average-current commercial ion accelerator that will deliver deuteron bunches to a 3 atmosphere deuterium gas cell target to produce neutrons by the D(d, n)3He reaction. Due to the high power density of such a tightly focused, modest-energy ion beam, the transport, controls, diagnostics, and in particular the neutron production gas target and beam stop approaches present significant engineering challenges. Progress and status on the building and early commissioning of the lab-scale demonstration machine shall be presented.
