Neutron Imaging Camera

摘要

The Neutron Imaging Camera (NIC) is based on the Three-dimensional Track Imager (3_DТI) technology developed atGSFC 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 > 0.5 MeV, arereconstructed from the momenta and energies of the proton and triton fragments resulting from ~3Не(n,p)~3Н interactionsin the 3-DTI volume. The performance of the NIC from laboratory is presented
