Materials research and non-destructive testing using neutron tomography methods

Abstract

Abstract This paper describes the modern tool of neutron tomography as an alternative and complement to the more common X-ray options and its potential for applications in materials research and engineering. Based on our own practical experiences, the challenges, success and limitations of neutron tomography are sketched and the potential for further improvements and methodical extensions is described. Using the performance at dedicated neutron imaging beam lines, there are many new aspects which only can be made available with neutron methods such as energy-selective imaging near Bragg edges, imaging with polarized neutrons and even imaging in the resonance region. Therefore, it is of high importance to get more and easier access to suitable beam ports at advanced neutron sources to make methodical progress and to attract more scientific and industrial users.
