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.
Journal ArticleDOI
Optimization of Nb3Sn and MgB2 wires
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.
Journal ArticleDOI
Phase Transformations During the Reaction Heat Treatment of Internal Tin Nb $_{3}$ Sn Strands With High Sn Content
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.
Journal ArticleDOI
