Abstract

Neutron imaging offers benefits over X-rays for steel corrosion studies including deep penetration and high sensitivity to some light elements such as hydrogen. However, the resolution is frequently at or below the thickness of the corroded layer. This work demonstrates two approaches to enhance the spatial resolution on IMAT at the ISIS neutron source. The first approach shows that a fiber optics taper attached to an optical camera box for white beam imaging can achieve a spatial resolution down to 15 μm. The second approach uses event centroiding with a Timepix3-based detector for diffraction contrast imaging achieving a spatial resolution of 30 μm. These results support advances in corrosion and degradation studies of steel using neutron imaging.

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
