NeXT-Grenoble, the Neutron and X-ray tomograph in Grenoble

Abstract

NeXT-Grenoble is a Neutron and X-ray Tomograph launched from the collaboration between the Universite Grenoble Alpes (UGA) and the Institut Laue Langevin (ILL). The design started in February 2016 shortly followed by its construction at ILL. A first version of the instrument has been opened to users since October 2016. One of the peculiarities of the instrument is that, as suggested by the name, the instrument allows the acquisition of truly simultaneous Neutron and X-ray tomographies, taking advantage of the high complementarity of these two beams. Also by virtue of the uniquely high flux at the ILL, the instrument can provide unprecedented spatial resolution (around 4μm true resolution, in few tens of seconds) and acquisition speed (1.5 s tomographies). This contribution details the adopted technical solutions and performances achieved, reviews some of the key published results and outlines the future direction of the instrument.
