LENS Webinars on New Directions in Instrumentation

Exploring the potential of neutron imaging and diffraction techniques
on IMAT instrument at ISIS, UK 

The need to enhance the material analysis capabilities at ISIS and 
complement the existing neutron instruments led to the construction of a 
new cutting-edge neutron imaging and diffraction beamline for materials 
science and engineering (IMAT) ^[1, 2] at the second target station at 
ISIS, UK. Currently, in addition to conventional ‘white-beam’ neutron 
radiography and tomography applications, IMAT is offering 
energy-selective imaging for mapping microstructural properties down to 
a spatial resolution of 50 microns. IMAT will also offer residual strain 
analysis, phase analysis and texture analysis by neutron diffraction 
starting 2022.

The complementarity between neutron tomography and neutron diffraction 
will be exploited through the tomography driven diffraction technique 
^[3] (TDD) based on the SScanSS software ^[4] for different samples 
drawn from the engineering, archaeology and geology. This approach will 
allow neutron-imaging investigations of samples followed by a detailed 
diffraction analysis of the regions of interest by selecting any point 
within the 2D or 3D sample. The diffraction scans could benefit from 
sample geometry acquired through imaging data, in terms of positioning 
accuracy, in order to get more focussed information about the stress 
state or the material’s composition at a particular point something 
which often cannot be obtained by diffraction alone.

Wide ranges of scientific and technological areas and topics have 
already been covered on IMAT spanning from engineering to life sciences. 
Moreover complementary studies with synchrotron imaging from other 
facilities (e.g. Diamond) are being considered to identify new ways of 
combining neutron and X-ray imaging research. The results achieved by 
scientists who had the opportunity to use IMAT neutron imaging 
capabilities look very promising unveiling new directions in our 
innovative interdisciplinary research.
