Brewer, Rebecca L.2009-12-042009-12-042009-12-04http://hdl.handle.net/2097/2230Improvised explosives devices (IEDs) are the cause of many casualties worldwide. Current methods for detecting IEDs are insufficient. A signature-based scanning technique based upon the fact that explosives consist primarily of hydrogen, oxygen, nitrogen, and carbon is examined as a possible rapid, standoff method for detecting IEDs. Devices employing this method rely on a template-matching technique in which the detector responses acquired through neutron and photon interrogation are compared to responses from a known explosive. A figure-of-merit is calculated to determine how well the template and the unknown match. This thesis explores the feasibility of employing the neutron interrogation aspect of this method.en-US© the author. This Item is protected by copyright and/or related rights.
