IMAT (Imaging and Materials Science & Engineering) is a neutron imaging and diffraction instrument for studies in a broad range of materials sciences. Non-destructive and in-situ testing of materials using neutrons is advantageous in many areas such as engineering science, battery research, earth science, cultural heritage and plant science.
IMAT currently provides equipment for neutron radiography, neutron tomography, and energy-resolved neutron imaging, with the following features:
- ability to cope with small samples, and heavy samples up to 1.5 tonnes
- field of view of up to 20x20 cm2 with a spatial resolution of ~200 microns
- spatial 3D resolution of 60 microns for small samples
- diffraction (Bragg edge) imaging options for strain and composition analysis with a resolution of a few hundred microns
- software for state-of-the-art volume reconstruction
Diffraction detectors (to be installed in the near future) will enable spatially-resolved neutron strain scanning, crystallographic phase analysis and texture analysis.

Many projects require one analysis technique, but having diffraction and imaging options on the same beamline enables new types of experiments. Residual stresses and phase compositions inside engineering-sized samples can be more effectively analysed if a diffraction scans is guided by radiographs.
The instrument was built with support from the Italian Research Council (CNR) and the Swedish Research Council (VR). The two large diffraction detector arrays at 90 degree scattering angles were funded by a project led by Prof. S. Eriksson from Chalmers University Gothenburg, Sweden. Energy-resolved neutron imaging is enabled by a detector based on microchannel plates (MCP) developed by Dr. A. Tremsin at Berkeley, USA, and by a CMOS (“GP2") detector developed in collaboration with Oxford University.
