Neutron and Synchrotron CT – Two complementary non-destructive inspection methods
Your benefits compared to lab-based analytics
Continuous improvements in material properties and production processes in industry mean that more sophisticated analytic techniques are required. Imaging methods such as computed tomography (CT) provide a three-dimensional view of the interior of objects without destroying them.
Synchrotron CT allows high transmission with light elements, and strong contrast with heavier elements. Neutron CT, on the other hand, allows strong contrast with light elements, and higher transmission with heavier elements.
This means that the two methods offer different yet complementary contrast possibilities.
Both Neutron and Synchrotron CT deliver high spatial resolution, high throughput and real-time investigations. The data obtained provide further analytical capabilities, as described below.
We are looking forward to working with you.
Imaging is used as a qualitative and quantitative measurement technology with the following analysis capabilities:
Material distribution analysis in 3D
- Visualization of the outer and inner structures and geometries of arbitrary and complex objects
- Segmentation of the object into its individual components and materials
Defect and porosity analysis in 3D
- Visualization of pores, blowholes and inclusions inside arbitrary and complex objects
- Quantitative information such as size, volume, shape and associated distributions
- Determination of the total percentage of defects and porosity, and presentation of results in a histogram
Wall thickness analysis in 3D
- Quantitative determination of the wall thicknesses of arbitrary and complex objects
- Localization of areas with insufficient or excessive wall thicknesses or gaps
Nominal/actual comparison analysis in 3D
- Direct geometrical comparison of CT data with CAD data of arbitrary and complex objects
- Quantitative information regarding deviations in the dimensions of an object compared with its CAD drawing
Reverse Engineering
- Physical reconstruction of arbitrary and complex objects without knowledge of design data
- Determination of external and internal object geometries
- Creation of an STL file for subsequent reverse engineering to a CAD model

The complementarity of Neutron and Synchrotron CT
Selection of advantages of each technique
Neutron CT
- Higher contrast for light elements (such as H, B, Li)
- Higher penetration of metallic elements (such as Ti, Cr, Fe)
- Higher contrast difference for neighbouring elements (as example Pd and Rh)
- Higher penetration of heavy elements (such as W, Au, Pb)
- See comparison of neutrons with X-rays (lab systems) of the periodic table
Synchrotron CT
- Higher penetration for light elements (such as H, B, Li)
- Higher contrast for metallic elements (such as Ti, Cr, Fe)
- Higher spatial resolution compared to neutrons and lab-based X-ray systems
- Much higher temporal resolution compared to neutrons and lab-based X-ray systems
- Much higher sample throughput compared to neutrons and lab-based X-ray systems
