The advantages of 14.1 MeV DT neutrons as an alternate source for the Nuclear Materials Identification System (NMIS) are mainly increased sensitivity and accuracy which will extend applications considerably as well as result in shorter measurement times for present applications. Since NMIS requires a neutron source of ~ 5 ∙ 10⁶ n/sec, a small, lightweight (<30 lbs. including the power supply and is 3-in.-OD pipe, ~ 4-ft. long) is under development at MF Physics Corporation for the Oak Ridge National Laboratory (ORNL). By associated particle (alpha) detectors, a cone of neutrons can be defined which is particularly useful for active neutron interrogation of fissile materials in containers. After final test at ORNL, this DT neutron source will be useful at the Y-12 National Security Complex for routine use with NMIS.
