| Abstract: | A novel approach has been studied for the characterization of specimens with a spatial resolution at the micron level. The technique dubbed Radioactive Ion Microscopy, "RIM" uses a beam of radioactive ions, specifically tritium ions, of sufficient energy to pass through a thick specimen (e.g. [greater than or equal to] 10 μm). After passage through the object, the ions are implanted in a stack of thin mylar sheets (1.5 microns thick). Their rest position is proportional to the thickness and the density of the sample transversed. The location of the radioactive species can be pinpointed by autoradiographing the successive mylar foils. Each picture represents a two-dimensional segment of the tridimensional density image of the specimen. The radiographs are photographed and converted into digital data which is used to generate a density map of the object. From these plots, physical and chemical features may be deduced... |
