Neutron detectors which use a novel technique for obtaining energy spectra are being investigated for applications in homeland security. Generally, energy spectra for neutrons are obtained by the time-of-flight technique where the time to travel a known distance is converted to an energy. The detectors being proposed and studied offer a new way to find energy spectra by differentiating events where the full energy of the neutron has been deposited within the detector volume. This work examines these detectors using simulations in Geant4 to determine the expected efficiencies and possible designs of the modules.
