Abstract
An apparatus for determining a direction of travel of a neutron emitted from a source includes: a chamber containing (i) nuclei that recoil upon interaction with an incoming neutron and (ii) atoms capable of being ionized by the recoiled nuclei thereby releasing electrons; an electron-interaction material disposed at the chamber and configured to receive electrons released by the ionized atoms and to emit photons upon the interaction with the received electrons; an imager configured to form an image of photons emitted by the electron-interaction material, wherein the image comprises a path having the direction of travel of the incoming neutron; and an orientation sensor configured to sense an orientation of the imager in order to relate the direction of travel of the incoming neutron to the orientation of the imager.
