Neutron Imaging (NRAD)
The Neutron Imaging Facility (NRAD) at Necsa’s SAFARI-1 research reactor is being upgraded to provide modern neutron radiography and tomography capabilities.
NRAD is currently unavailable for routine measurements and beam-time applications. Users will be informed when the upgraded facility becomes operational. In the interim, Necsa’s instrument scientists can assist researchers with preparing proposals to access suitable international neutron imaging facilities.
Capabilities
Neutron imaging is a non-destructive examination technique that produces two-dimensional radiographs and three-dimensional tomographic datasets. It complements X-ray imaging because neutrons interact differently with matter. The technique offers:
- Penetration through dense metals and other materials that strongly attenuate X-rays
- High sensitivity to light elements, particularly hydrogen
- Non-destructive visualisation of internal structures and concealed features
- Analysis of water and fluid movement within materials and systems
- Inspection of assembled components without cutting or dismantling them
Typical Applications
- Non-Destructive Examination
- Hydrogen and Energy Technologies
- Agriculture and Plant Science
- Palaentology and Heritage Science
- Civil Engineering
- Metallurgy
- Nuclear Engineering
- Geoscience and Petrophysics
Research and Training Support
The NRAD facility is intended to support academic research, industrial applications and postgraduate training. Instrument scientists can assist users with technique selection, experimental planning, sample assessment, proposal development and data interpretation.
Access to the Facility
NRAD is not currently accepting routine beam-time applications while the facility is being upgraded. Researchers interested in future access or assistance with proposals to international facilities should contact the BLC User Office at UserOffice@necsa.co.za.
