    • High-energy photon transport modeling for oil-well logging 

      Johnson, Erik D., Ph. D. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2009)
      Nuclear oil well logging tools utilizing radioisotope sources of photons are used ubiquitously in oilfields throughout the world. Because of safety and security concerns, there is renewed interest in shifting to ...
    • Monte Carlo model of a low-energy neutron interrogation system for detecting fissile material 

      Johnson, Erik D., Ph. D. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2006)
      (cont.) Further MCNP simulations of the neutron source impinging on cargo containers suggest that this technique can respond, as expected, qualitatively differently to containers containing SNM from containers that do not. ...
