EDS-GRT System ConfigurationPatents by Scientific Innovations, Inc. An accelerator is used to produce protons at a specific energy such that unique resonant gamma rays are generated from impingement on a specific target. The emitted gamma rays pass through a volume of interest and interact resonantly with specific elements of interest so that images of the elemental density are developed from the variation in gamma detection counts. Fluorescence or scattered gammas resonant with the element are also detected simultaneously. Non resonant gamma rays are used to image total density.

EDS-GRT: Basic Principles Gamma Resonance occurs when the energy of a gamma beam is precisely tuned to coincide with a nuclear excitation level in a nucleus of an element of interest. GRT can be implemented in either absorption (transmission) or scattering mode. Scientific Innovations, Inc Brookhaven National Laboratory
Target A low energy proton beam hits a dedicated target and produces resonance gamma rays. These interact resonantly with N or Cl encountered in the explosive. Monitoring the transmitted and the scattered beams, with the transmission and scattering detectors, respectively, allows analysis and imaging of the elements of interest. Accelerator Protons Scattering Detectors Object Scattered Beam Transmitted Beam Transmission Detectors EDS-GRT: Basic Configurations Scientific Innovations, Inc Brookhaven National Laboratory
EDS-GRT: Transmission Setup measures simultaneously the resonantt and non resonant gamma ray flux and can differentiate between the two. The ratio of the two identifies the explosive At 9.17 MeV gamma ray resonance attenuation is about four times higher than the non resonant radiation.
