AB - Lawrence Livermore National Lab (LLNL) is developing an intense, high-brightness fast neutron source to create sub-mm-scale resolution neutron radiographs and images. A pulsed 7MeV, 300μA average-current commercial deuteron accelerator will produce an intense source (10¹¹ n/s/sr at 0 deg) of fast neutrons (10MeV) using a novel neutron target with a small (1.5mm diameter) beam spot size to achieve high resolution. A highly flexible multi-accelerator beamline has been developed allowing for the use of both 4MeV and 7MeV RFQ/DTL deuteron accelerators. TRACE3D has been used to model the beam transport and design the quadrupole lattice and results will be presented including iterated design within beamline mechanical constraints, sensitivities, and multiple use of the magnets. Because of the high power density of such a tightly focused, modest-energy ion beam, intercepting beam diagnostics are extremely challenging, motivating novel concepts and extensions of current techniques to higher average power densities. Full duty factor beamline diagnostics will be discussed including charge, position, emittance via beam-induced fluorescence, and a full power beam dump and Faraday cup.
