Abstract: A method for operating an X-ray or neutron-optical system and beam stop comprising an X-ray or neutron source (1) from which corresponding radiation is guided as a primary beam (2) to a sample (4) under investigation, with an X-ray or neutron detector (6) for receiving radiation diffracted or scattered from the sample (4), wherein the source (1), the sample and the detector are disposed substantially on one line (=z-axis) and wherein a beam stop (5; 31; 41) is provided between the sample and the detector whose cross-sectional shape is adjusted to the cross-section of the primary beam is characterized in that the beam stop is disposed to be displaceable along the z-direction for optimum adjustment of the amounts of useful and interfering radiation impinging on the detector. This protects the detector from the influence of the primary beam while allowing a maximum amount of diffracted or scattered radiation to reach the detector, wherein the beam stop can be easily adjusted to temporally changing properties of the beam optics.

Abstract: Disclosed herein are methods and systems of scanning a target for potential threats using the energy spectra of photons scattered from the target to determine the spatial distributions of average atomic number and/or mass in the target. An exemplary method comprises: illuminating each of a plurality of voxels of the target with a photon beam; determining an incident flux upon each voxel; measuring the energy spectrum of photons scattered from the voxel; determining, using the energy spectrum, the average atomic number in the voxel; and determining the mass in the voxel using the incident flux, the average atomic number of the material in the voxel, the energy spectrum, and a scattering kernel corresponding to the voxel. An exemplary system may use threat detection heuristics to determine whether to trigger further action based upon the average atomic number and/or mass of the voxels.

Abstract: A non-intrusive container inspection system, including apparatuses and methods, for non-intrusively scanning and inspecting containers employed to transport items therewithin that utilizes forward-scattered bremsstrahlung, or x-rays, for generating multi-plane images of items present within the containers and for distinguishing between multiple materials present in such items. The system is adapted to direct a pulsed bremsstrahlung, or x-ray, beam having multiple spectra in a substantially single direction at a container being scanned and to produce data that corresponds to portions of the beam that either pass through items within the container without being scattered or that are forward-scattered by items within the container. The system employs a detector array having sections specially configured and oriented to receive and produce data corresponding to the non-scattered and forward-scattered portions of the beam.

Abstract: A non-uniform density sample analyzing method for analyzing a distribution state of particle-like matter in a non-uniform density sample, where an actually measured X-ray scattering curve is an in-plane X-ray scattering curve obtained by in-plane diffraction measurement, and fitting between the in-plane X-ray scattering curve and the simulated X-ray scattering curve is performed. The value of the fitting parameter when the simulated X-ray scattering curve agrees with the in-plane X-ray scattering curve serves to indicate the in-plane direction distribution sate of the particle-like matter in the non-uniform density sample. This method can analyze the in-plane direction distribution state of the particle-like matter in the anisotropic non-uniform density sample easily and accurately. Its device and system are also disclosed.

Abstract: Disclosed herein is a method of evaluating the performance of an ion-exchange film. In the method, small-angle scattering curves for the ion-exchange film are obtained by an X-ray measuring apparatus that can detect X-rays scattered at small angles with respect to the axis of an X-ray applied to film. From the positions of the peaks on the small-angle scattering curves and the X-ray intensities at these peaks, the molecular structure of the ion-exchange film is determined, thereby to evaluate the performance of the ion-exchange film.

Abstract: An X-ray optical system for small angle scattering has a parabolic multilayer mirror and, so that switching to other X-ray incident optical systems for X-ray analysis can be easily performed. A parabolic multilayer mirror, an optical-path selecting slit device, a small-angle selecting slit device and a Soller slit are arranged between an X-ray source and a specimen-side slit. An X-ray beam having passed through the first aperture of an aperture slit plate is interrupted by the optical-path selecting slit. An X-ray beam having passed through the second aperture of the aperture slit plate is reflected at the reflecting surface of the multilayer mirror to become a parallel beam. This parallel beam passes through an aperture of the optical-path selecting slit device. The beam width is restricted by a narrow slit of the small-angle selecting slit device.

Abstract: A system and method for inspecting an enclosure with penetrating radiation. Radiation side-scattered from an object within the enclosure is detected, allowing the object to be located. If the object is deemed suspect, a volume element of the suspect object is further irradiated with penetrating radiation, and radiation coherently-scattered by the volume element is detected. The energy spectrum and angular distribution of the coherently-scattered radiation are used to characterize the volume element of the suspect object.
