Los Alamos activities on HE detection using nuclear resonance absorption technique
- Thomas J. T.
The feasibility of detecting high explosives through the nitrogen nuclear resonance absorption of the 9.17-MeV gammas produced by carbon-13 nuclei via radiative capture of 1.75-MeV protons was demonstrated almost ten years ago at Los Alamos National Laboratory. The practical application of this technique requires advances in several enabling technologies. The most important issue is the generation of a high quality proton beam with appreciable current (>10 mA) to produce the minimum number of resonance gammas to achieve the required throughput in baggage/cargo interrogation. We have performed a parameter study of the use of a compact cyclotron as an injector to a proton storage ring with energy recovery and electron cooling capability to maximize the intensity of the proton beam. We have also started our computational effort in applying MCNPX in our newly developed radiographic chain model to model the radiographic imaging process. Details of our studies will be presented.
