  • Anisotropic neutron scatter method and apparatus
    Patent number: 5440136
    Abstract: A non-invasive inspection system employs the isotropic, resonant scattering of neutrons from an object to determine the presence of at least one preselected element therein. A monoenergetic neutron beam is impinged onto the object and a first detector is disposed to detect neutrons resonantly scattered by the preselected element. A second detector is disposed to detect non-resonantly scattered neutrons. Comparison of the signals from the two detectors is indicative of resonant scattering and hence presence of the preselected element.

  • Energy discriminating, resonant, neutron detector
    Patent number: 5142153
    Abstract: A neutron detector includes a constituent or added sensitizer which enhances the detector's response to neutrons, of a preselected energy. Also disclosed are analytical techniques employing the detector, including a double resonance technique.

  • Neutron scatter method and apparatus for the noninvasive interrogation of objects
    Patent number: 4918315
    Abstract: A system and method for the inspection and/or search for concealed objects impinges a monoenergetic neutron beam upon an object, notes the energy distribution of the neutrons scattered from the object and correlates the energy/intensity distribution of the scattered neutrons with the presence or absence of particular elements. The invention may be utilized to obtain qualitative or quantitative data regarding the composition of the object under interrogation.

  • Method and apparatus for the noninvasive interrogation of objects
    Patent number: 4864142
    Abstract: Neutron elastic scatter resonance is employed for the noninvasive interrogation of objects as for example to detect explosives and narcotics in closed containers. A resonant scattering spectrum of the object is obtained by projecting a collimated, monoenergetic beam of neutrons onto the object, varying the energy of the beam and measuring the scattered neutrons as a function of the beam energy. The thus generated spectra and analyzed so as to determine either the pressence of particular elements of interest or the relative ratios of those elements. Ratios so determined may be compared with corresponding ratios established for contraband items. If the ratios fall within the range for contraband, an alarm indication is provided. The present invention provides method and apparatus for contraband detection.
