  2. Fast neutron resonance radiography for element imaging : theory and applications

    Chen, Gongyin, 1968-Massachusetts Institute of Technology2001

    Fast Neutron Resonance Radiography (NRR) has been devised as an elemental imaging method, with immediate applications to detecting explosives and drugs in passenger suitcases. In the NRR method, the 2-D elemental mapping of hydrogen, carbon, nitrogen, oxygen and the sum of other elements are …

  3. Computational treatments for neutron resonance elastic scattering in Monte Carlo nuclear simulations

    Tran, Vivian YMassachusetts Institute of Technology2016

    … This work investigates the phenomenon of neutron resonance scattering with a moving target, which can affect the post-collision properties of the neutron and macroscopic values such as temperature reactivity coefficients. First, this research validates a faster computational treatment for …

  4. Towards the development of an explosives detection system using Neutron Resonance Radiography

    Raas, WhitneyMassachusetts Institute of Technology2007

    … that mandate screening 100% of checked luggage. Neutron Resonance Radiography (NRR) has been under investigation as a supplement to conventional x-ray systems as a non-invasive, non-destructive means of detecting explosive material in checked luggage. Using fast (1-6 MeV) neutrons produced by an …

  8. Exclusive π- Electro-Production From the Neutron in the Resonance Region

    Zhang, Jixie2019

    <p>The study of baryon resonances is crucial to our understanding of nucleon structure. Although the excited states of the proton have been studied in great detail, there are very few data available for the neutron resonances because of the difficulty inherent in obtaining a free neutron target. To …
