摘要：

We describe the Neutron Imaging Camera (NIC) being developed for the detection of special nuclear material by NASA/Goddard Space Flight Center (GSFC) and NSWC/Carderock. The NIC is a self-contained, robust, omnidirectional, and 3 He-independent neutron detector based on the Three-Dimensional Track Imager (3-DTI) technology developed at GSFC for gamma-ray astrophysics applications. The 3-DTI, a large volume, gas, time-projection chamber, provides accurate, similar to 0.4 mm resolution, 3-D tracking of charged particles. The incident direction of fast neutrons, 0.1 MeV < E-n < 10 MeV, are reconstructed from the momenta and energies of the protons resulting from single and double (n, p) scatters in methane (CH4). We present angular and energy resolution performance of the NIC derived from the field test at Ft. Monroe, VA in September 2010.
