What is Ion Beam Analysis?
Ion Beam Analysis (IBA: see also Case Studies) involves the use of an energetic ion beam to probe the surface of a material to reveal its elemental and structural details. New methods are being developed which also give information on the chemical (bonding types) and molecular (bonding arrangement) of materials. The ion beams themselves can be focussed to sub-micron sizes and raster-scanned over the sample to give maps and 3D images of the structural and elemental/molecular distributions of a target material. This analysis may be performed in vacuum or in air. (See Applications.)
