Active interrogation using neutrons is an effective method for detecting shielded nuclear material. A lightweight; lunch-box-sized; battery-operated neutron source would enable new concepts of operation in the field. We have developed at-scale components for a highly portable; completely self-contained; pulsed Deuterium-Tritium (DT) neutron source producing 14MeV neutrons with average yields of 107n/s. A gated; field ionization ion source using etched electrodes has been developed that produces pulsed ion currents up to 500nA. A compact Cockcroft-Walton high voltage source is used to accelerate deuterons into a metal hydride target for neutron production. The results of full scale DT tests using the field ionization source are presented. © 2014 AIP Publishing LLC;
