NeXT-Grenoble is a Neutron and x-ray imaging facility developed and now running in Grenoble, born from a collaboration between the University Grenoble Alpes and the European Neutron Source the Institut Laue-Langevin (ILL). This instrument will ultimately combine the uniquely intense neutron flux offered by the ILL with laboratory x-ray tomography in order to obtain simultaneous bi-modal imaging, thus allowing the complementarity of these methods to be exploited.
As a preliminary step, a medium resolution neutron radiography/tomography instrument has been implemented in 2016 allowing cultural heritage, academic and industrial users to perform successful material characterisations in a wide range of applications such as porous/geomaterials, hydrogen fuel cells, medical prosthetics and archeological artefacts. In several cases tomographic acquisitions were obtained during in-situ hydro-thermo-chemo-mechanical tests, for example using bespoke high confinement triaxial or tensile loading rigs, or imposing high-temperature conditions, running multi-phase permeability tests as well as inducing electrochemical reactions.
The planned addition in 2017/2018 of an integrated x-ray tomograph, as well as the implementation of a newly developed high-resolution neutron detector, is expected to push boundaries still further and permit the visualisation of interactions between complex phenomena in areas such as geomaterial permeability, hydraulic fracturing and concrete behavior under extreme conditions, as well as complicated cultural heritage artefacts containing organic and in-organic matter.
