TL;DR: In this article, the effect of Ta, Ti and Ta+Ti additives on the physical properties of Nb3Sn multifilamentary wires with optimized critical currents is discussed.

TL;DR: The Conductor Development Program aiming to reach a non-copper critical current density of 1500 A/mm 2 at 16 T and 4.2 K has been launched by CERN, with the involvement of industry and laboratories worldwide.

TL;DR: In this paper, the authors investigated the site occupancy of Ta and Ti additives in Nb3Sn wires and showed that the Ta atoms occupied the 6c chain sites, while the Ti atoms were located on the cubic 2a sites.

TL;DR: In this article, synchrotron X-ray diffraction measurements during in-situ reaction heat treatment (HT) of a state-of-the-art high Jc Nb3 Sn internal tin strand are reported.

TL;DR: In this article, the relationship between lattice deformations and superconducting properties of Nb3Sn wires has been clarified using high-energy x-ray diffraction experiments at the European Synchrotron Radiation Facility (ESRF) in Grenoble.
