TL;DR: The high flux of high energy X-rays that can be provided through state-of-the-art high energy synchrotron beam lines has enabled a variety of new experiments with the highly absorbing Nb3Sn superconductors.

TL;DR: In this paper, the lattice parameter changes in three types of Nb3Sn superconducting wires during uniaxial stress-strain measurements at 4.2 K have been measured by high-energy synchrotron x-ray diffraction.

TL;DR: In this article, the evolution of Nb containing phases during the diffusion heat treatment of three different high critical current Nb3Sn strand types is compared, based on synchrotron X-ray diffraction results that have been obtained at the ID15 beam line of the European Synchoretron Radiation Facility (ESRF).

TL;DR: In this article, the formation of coarse Nb3Sn grains in Internal Tin (IT) strands has been studied at the example of a prototype strand with high Sn content, and Metallographic examination revealed that the comparatively low critical current density (Jc) of this strand is partly due to the formation, at the periphery of the individual filaments within the subelements.

TL;DR: In this paper, the electromechanical behavior of a Nb3Al wire manufactured according to the RHQT process (rapid heating, quenching and transformation) has been investigated at magnetic fields between 15 and 19 T at 4.2 K.
