We describe the Neutron Imaging Camera (NIC) being developed for DTRA applications by NASA/GSFC and NSWC/CD. The NIC is based on the Three-Dimensional Track Imager (3-DTI) technology developed at GSFC for gamma-ray astrophysics applications. The 3-DTI, a large volume time-projection chamber, provides accurate ∼0.4 mm resolution, 3-D tracking of charged particles. The incident direction of fast neutrons, E n ≳ 0.1 MeV, are reconstructed from the momenta and energies of the proton and triton fragments resulting from 3He(n,p)3H interactions in the 3-DTI volume. We present angular resolution performance of the NIC derived from accelerator tests.

Neutron Imaging Camera

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 3He-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, ∼04 mm resolution, 3-D tracking of charged particles The incident direction of fast neutrons, 01 MeV n 4 ) We present angular and energy resolution performance of the NIC derived from the field test at Ft Monroe, VA in September 2010

The Neutron Imaging Camera (NIC) is based on the Three-dimensional Track Imager (3_DTI) technology developed at
GSFC for gamma-ray astrophysics applications. The 3-DTI, a large volume time-projection chamber, provides accurate,
~0.4 mm resolution, 3-D tracking of charged particles. The incident direction of fast neutrons, En > 0.5 MeV, are
reconstructed from the momenta and energies of the proton and triton fragments resulting from 3He(n,p)3H interactions
in the 3-DTI volume. The performance of the NIC from laboratory is presented.

Gamma-ray observations in the medium energy range (0.50-50.0 MeV) are central to unfolding many outstanding questions in astrophysics. The challenges of medium-energy gamma-ray observations, however, are the low photon statistics and large backgrounds. We review these questions, address the telescope technology requirements, and describe our development of the 3-Dimensional Track Imaging (3-DTI) Compton telescope and its performance for a new medium-energy gamma-ray mission. The 3-DTI is a large-volume time projection chamber (TPC) with a 2-dimensional gas micro-well detector (MWD) readout.
