Imaging
Necsa’s imaging facilities use X-ray and neutron techniques to investigate the internal structure of objects and materials non-destructively at the micron scale. These techniques produce two-dimensional radiographs and three-dimensional tomographic datasets that reveal internal features, defects and variations in density or composition. X-rays provide strong contrast between materials of different densities and are suitable for high-resolution imaging. Neutrons provide complementary contrast, penetrate certain dense materials and are particularly sensitive to light elements such as hydrogen.
Research and Industrial Applications
The facilities support academic research, industrial projects and technology development in areas such as:
- Materials science and engineering
- Geology and mining
- Palaeontology, archaeology and cultural heritage
- Anatomy, biomedical science and dentistry
- Agriculture and biological sciences
- Manufacturing and product development
- Quality assurance and non-destructive examination
Services
Necsa provides the following imaging services:
- Two-dimensional X-ray radiography
- Three-dimensional X-ray computed tomography
- Non-destructive examination of objects, samples and components
- Detection of internal features, defects and density variations
- Image reconstruction, processing and analysis
- Experimental planning and interpretation of results
Instruments
Detailed descriptions of the instruments, together with example applications, are available at the following links:
- Micro-focus X-ray Radiography and Tomography (MIXRAD) — high-resolution X-ray radiography and three-dimensional computed tomography using a NIKON XTH 225 ST micro-focus X-ray system
- Neutron Imaging (NRAD) — neutron radiography and tomography for applications requiring penetration through dense materials or sensitivity to light elements such as hydrogen
MIXRAD is operational and available for project proposals. The NRAD facility is currently being upgraded and is not available for routine beam-time applications. Instrument scientists can however assist researchers with preparing proposals to access suitable international neutron imaging facilities during the upgrade.
Training and Research Support
The Imaging section supports researchers and postgraduate students through training in experimental methods, image reconstruction and data analysis. Instrument scientists assist users with experimental planning, technique selection, sample assessment, scanning and interpretation of results.
Access to the Facilities
Academic applications are evaluated on scientific merit, while industrial work is undertaken through contract-research arrangements. Prospective users should contact the relevant instrument scientist to discuss project feasibility, sample requirements and availability before applying through the BLC User Office.
