Simultaneous neutron transmission and diffraction imaging investigations of single crystal nickel-based superalloy turbine blades

The integrity of turbine blades is at the heart of every operating aerospace engine or land-based gas turbine. In the most demanding environments, they are cast as single crystals. Whereas traditional neutron imaging is an excellent tool for the non-destru ...

Energy-selective neutron imaging for materials science

Steven Luc X Peetermans

Common neutron imaging techniques study the attenuation of a neutron beam penetrating a sample of interest. The recorded radiograph shows a contrast depending on traversed material and its thickness. Tomography allows separating both and obtaining 3D spati ...

Cold neutron diffraction contrast tomography of polycrystalline material

Steven Luc X Peetermans, Andrew King

Traditional neutron imaging is based on the attenuation of a neutron beam through scatteririg and absorption upon traversing a sample of interest. It offers insight into the sample's material distribution at high spatial resolution in a non-destructive way ...

A new transmission based monochromator for energy-selective neutron imaging at the ICON beamline

Steven Luc X Peetermans

A new type of monochromator has been developed for energy-selective neutron imaging at continuous sources. It combines the use of a mechanical neutron velocity selector with pyrolytic graphite crystals of different mosaicity. The beam can be monochromatize ...

Simultaneous neutron transmission and diffraction contrast tomography as a non-destructive 3D method for bulk single crystal quality investigations

Steven Luc X Peetermans

Traditional neutron tomography allows to reconstruct the attenuation cross section, a measure for the material distribution, at high spatial resolution and non-destructively. However, it does not state anything about the ordering structure of the atoms ins ...

Energy-selective neutron imaging for morphological and phase analysis of iron-nickel meteorites

Steven Luc X Peetermans

We propose energy-selective neutron imaging as a new and non-destructive method to investigate rare metallic meteorites. It is based on attenuation of a neutron beam of limited spectral distribution in a sample depending on the elemental composition and cr ...
