Imaging Plates

Small-angle neutron scattering (SANS) measurements have been performed on long-flight-path pinhole-collimation SANS instruments using, as a two-dimensional position-sensitive detector, both a neutron imaging plate, incorporating gadolinium, and a two-step transfer method, with dysprosium foil as the image transfer medium. The measurements are compared with corresponding data taken using conventional position-sensitive gas proportional counters on the SANS instruments in order to assess the viability of the imaging techniques. The imaging plates have pixel sizes of about two orders of magnitude smaller than those of the gas proportional counter. The reduced pixel size provides definite advantages over the gas counter in certain specific situations, namely when limited space necessitates a short sample-to-detector distance, when only small samples (comparable in size to the detector pixels) are available, or when used in conjunction with focusing beam optics.

Area Of Interest

Neutron imaging has enjoyed a flurry of activity and application in recent years. The construction of dedicated beamlines at various neutron sources has demonstrated the significant interest among the science and engineering communities, with particular relevance to industrial applications, the nondestructive testing of components and imaging of precious archaeological artefacts. Here two methods are demonstrated of how neutron imaging can be performed using a conventional small-angle neutron scattering (SANS) instrument, such as D33 at the Institut Laue–Langevin, with spatial resolutions down to about 100 µm. The first is a magnified imaging technique from a quasi-point-like source with the magnified image recorded on the usual low-resolution SANS detector. The second method uses a fine beam in a raster-scan measurement over the area of interest. Images can be reconstructed either using the transmitted beam, as in conventional radiographic imaging, or from scattering data, giving access to transmission radiographic images as well as the dark-field or scattering contrasts and phase-contrast images.
