Directional Fast Neutron Detection Using a Time Projection Chamber
arXiv:1010.1306 · doi:10.1016/j.nima.2010.09.010
Abstract
Measurement of the three dimensional trajectory and specific ionization of recoil protons using a hydrogen gas time projection chamber provides directional information about incident fast neutrons. Here we demonstrate directional fast neutron detection using such a device. The wide field of view and excellent gamma rejection that are obtained suggest that this device is well suited to searches for special nuclear materials, among other applications.
