Abstract

The key physical processes of a resonance-absorption-based explosive detection system (EDS) were individually computed modeled so that subsystem and total system performance could be simulated (i.e., a virtual prototype). Processes that were modeled included the radiofrequency quadrupole proton beam, resonant-energy gamma ray production by the reaction ¹³C(p,(gamma) )¹⁴N), gamma ray transport through inspected objects, individual detector response, output of a tomographic detector array, and tomographic image reconstruction. The simulations were used in designing individual subsystems of a laboratory EDS and in assessing their effect on overall system performance. The models were benchmarked to the actual performance of the prototype in developing performance requirements for an airport EDS. The several computer codes used in the simulation are described and the effectiveness of the overall simulation effort is discussed.
