A procedural solution for determining the temperature dependence of transport critical current in Nb$_{3}$Sn superconducting wires using magnetization measurements / Pong, Ian (LBNL, Berkeley) ; Ekin, Jack (NIST, Boulder) ; Baumgartner, Thomas (Vienna, Tech. U.) ; Bordini, Bernardo (CERN) ; Cheggour, Najib (Florida State U.)
Using magnetization techniques to determine the temperature dependence of critical current in Nb$_{3}$Sn wires is attractive because of the relative ease compared with using variable-temperature transport measurements. However, there is a known mismatch in the temperature scaling characterizations when using magnetization data compared to transport data. [...]

Investigating the effect of rolling deformation on the electro-mechanical limits of Nb$_{3}$Sn wires produced by RRP$^{®}$ and PIT technologies / Bagni, T (U. Geneva (main) ; Uppsala U.) ; Calzolaio, C (PSI, Villigen) ; Bovone, G (U. Geneva (main)) ; Ferradas-Troitino, J (CERN) ; Barth, C (CERN) ; Ballarino, A (CERN) ; Senatore, C (U. Geneva (main))
Future high-field magnets for particle accelerators hinge on the crucial development of advanced Nb$_{3}$Sn wires engineered to withstand the large stresses generated during magnet assembly and operation. The superconducting properties of Nb$_{3}$Sn enable the design of compact accelerator-quality magnets above 10 T, but at the same time the brittleness and strain sensitivity of the material impose careful consideration of the mechanical limits. [...]

Advances in Nb$_{3}$Sn performance / Godeke, A (LBNL, Berkeley)
Nb$_{3}$Sn wires with non-Cu critical current densities (Jc) that surpass 3 kAmm−2 at 12 T and 4.2 K are commercially available in piece lengths longer than 10 km. Acceleratortype magnets that utilize these conductors have achieved record magnetic fields. [...]

Influence of the Heat Treatment on the Layer JC of Internal-Sn Nb3Sn Wires With Internally Oxidized Nanoparticles / Lonardo, F (Geneva U.) ; Bovone, G (Geneva U.) ; Buta, F (Geneva U.) ; Bonura, M (Geneva U.) ; Bagni, T (Geneva U. ; Uppsala U.) ; Medina-Clavijo, B (CERN) ; Ballarino, A (CERN) ; Hopkins, S C (CERN) ; Boutboul, T (CERN) ; Senatore, C (Geneva U.)
We evaluated various heat treatments (HT) for maximizing the Nb3Sn layer thickness while retaining a refined grain microstructure in low filament count internal-Sn Nb3Sn Rod-In-Tube wires with internally oxidized nanoparticles. These wires were manufactured in our laboratory using SnO2as oxygen source and Nb alloys containing Ta and Zr or Hf. [...]

Influence of Axial Strain and Transverse Compressive Load on Critical Current of Nb3Sn Wires for the FCC / Nakamoto, M (Sokendai, Tsukuba) ; Sugano, M (KEK, Tsukuba) ; Dhakarwal, M (KEK, Tsukuba) ; Ogitsu, T (KEK, Tsukuba) ; Nishijima, G (Tsukuba Magnet Lab.) ; Awaji, S (Tohoku U. (main)) ; Kawashima, S (Kobe Steel) ; Hopkins, S C (CERN) ; Ballarino, A (CERN)
Nb 3 Sn superconducting wires are under consideration for producing high field accelerator magnets for the proposed Future Circular Collider (FCC) due to their high critical field. R&D; studies are ongoing worldwide with a target non-Cu critical current density ( Jc ) of 1500 A/mm 2 at 4.2 K, 16 T. [...]

Degradation of I $_{c}$ due to residual stress in high-performance Nb$_{3}$Sn wires submitted to compressive transverse force / Senatore, C (U. Geneva (main) ; Geneva U.) ; Bagni, T (U. Geneva (main)) ; Ferradas-Troitino, J (U. Geneva (main) ; CERN) ; Bordini, B (CERN) ; Ballarino, A (CERN)
Future particle colliders in search for new physics at the energy frontier require the development of accelerator magnets capable of producing fields well beyond those attainable with Nb-Ti. As the next generation of high-field accelerator magnets is presently planned to be based on Nb$_{3}$Sn, it becomes crucial to establish precisely the mechanical limits at which this brittle and strain sensitive superconductor can operate safely.
