Improved analysis techniques for new applications in neutron imaging

Neutron imaging provides a method for high contrast imaging of many low density materials in combination with high density materials. For samples with suitable material composition this makes neutron imaging techniques very valuable in comparison to the more common X-ray techniques. The two neutron imaging beamlines at the Swiss Spallation Neutron Source (SINQ) serve a wide user community with applications for material inspection and materials research, geo-science, cultural heritage studies, and energy production and storage. For this purpose, the beamlines have evolved into versatile instruments that can be modified to meet the user requests in short time. We show some recent results to demonstrate the performance of the imaging facilities. Topics covered by the examples are combined spatially and time resolved imaging, low contrast imaging, high resolution imaging of large samples. Neutron tomography on different size scales is used in routine mode. Often, these investigations operate close to the limit of the instrumentation or even the limits of analysis methods. The examples represent applications from construction engineering, combustion engine engineering, and electro-chemistry.
