Deep insights for designed materials
Experimental methods in neutron physics have earned increasing interest as a
tool to analyse and modify material properties. This is in particular done in materials sciences, engineering anf other
technical fields. The reason is mainly that neutrons interact with nuclei and therefore respond to
other elements than X-rays and that they can penetrate deeply into materials and change elements because of their lacking
charge.
Imporatnt applications are residual stress analysis, non-destructive inspection of the interior of components and
workpieces by
transmission measurements,
composition analysis
(neutron activation analysis)
and the production of radio isotopes for engineering, medicine and environmental monitoring.

Investigations with neutrons were performed at the radiography station NEUTRA
in 1999 on very different samples of industrial partners. Most of the questions
could be solved using high resolution neutron transmission techniques. The need
for methodical and analytical improvement becomes obvious for the remaining
unsolved problems.
