Abstract:
Small angle neutron scattering (SANS) is a well established tool for the determination of microscopic structures in various materials. With the ultra small angle neutron scattering technique (USANS) structures with sizes of approximately 50 nm to 50 µm can be resolved by a double crystal diffractometer (DCD). USANS signals recorded with a special DCD were used for tomographic purposes investigating the macroscopic structure of a sample. Thereby regions within the sample with different ultra small angle scattering properties i.e. with different microscopic structures could be imaged by the means of tomographic reconstruction from projections (on a macroscopic scale).
