Abstract:Lawrence Livermore National Laboratory (LLNL) is near-completion of a quasi-monoenergetic neutron source for fastneutron imaging and computed tomography (CT). The source is expected to produce 10-MeV neutrons with an on-axis flux of ~1011 per second per steradian through a collimated aperture with a ~7-degree opening angle. The application for this source is imaging and CT of low-Z materials heavily shielded by high-Z materials. Fast-neutron imaging and CT is a non-destructive technique for very thick objects.… Show more
