Abstract :
We have successfully ruggedized and deployed a field portable fast-neutron imager. Detection efficiency has been increased by > 5x more over the one fielded last year. Imaging has been demonstrated though 30 cm thick concrete and at a stand-off distance of 75 m in air. We have also imaged a pulsed D-D neutron generator and recorded its energy spectrum. These demonstrations show that our neutron scatter camera could be a useful tool not only in the lab but as a field detector for hidden SNM.
