  • Extending the dynamic range of the TGS through the use of a dual intensity transmission beam
    Patent number: 7541590
    Abstract: A method for automating and extending the density range for gamma ray attenuation correction algorithms for all classes of non-destructive assay systems including those without automated shutters or automated collimators. A system and software for implementing the method are also provided. The system features a dual-intensity transmission source and utilizes a three pass scanning protocol. The high-energy source in conjunction with a beam modulator produces a high and low energy beam. Automated software determines which beam data to use in tomographic reconstruction of an object being scanned.

  • Method for reduction in the interference of cosmic ray-induced neutron events in passive neutron coincidence and multiplicity counting
    Patent number: 6509563
    Abstract: In a preferred embodiment, a method of enhancing the neutron coincidence assay of low fissile mass samples, by combining assay precision improvement algorithms with novel background and matrix correction algorithms, to provide lower levels of detection with higher confidence that the reported results are not subject to biases resulting from environmental or sample matrix effects.
