In the production of Rutherford cables, Nb 3 Sn strands are subjected to severe deformation; and to evaluate this degradation prior to cabling, uniaxial rolling with a thickness reduction of ∼15% has often been used. The effects of this deformation on superconducting performance differ significantly between wire designs. [...]

Analysis and Modeling of Damage in RRP Nb$_{3}$Sn Wires During Cabling
/ Rochepault, E (LBNL, Berkeley ; CERN) ; Arbelaez, D (LBNL, Berkeley) ; Pong, I (LBNL, Berkeley) ; Dietderich, D R (LBNL, Berkeley)
High-critical current density (J_c) Nb_3Sn wires such as restacked-rod process wires are used in Rutherford cables for high-field superconducting magnets. However, during cabling, the wires experience strong plastic strains, which break some superconducting sub-elements and can degrade the electromagnetic performances. [...]

Finite Element Model to Study the Deformations of Nb$_{3}$Sn Wires for the Next European Dipole (NED)
/ Farinon, S (INFN, Sezione di Genova, Genova, Italy) ; Boutboul, Thierry (CERN) ; Devred, Arnaud (CEA/Saclay, DSM/DAPNIA/SACM, Gif-sur-Yvette Cedex, France ; CERN) ; Fabbricatore, P (INFN, Sezione di Genova, Genova, Italy) ; Leroy, Daniel (CERN) ; Oberli, Luc-Rene (CERN)
The Next European Dipole (NED) activity is aimed at the development of a large-aperture, high-field superconducting magnet relying on high-performances Nb$_{3}$Sn conductors. Part of the NED program is devoted to the mechanical study of a new generation of Nb$_{3}$Sn wires and to predict and describe their behavior under the severe loading conditions of the cabling process.

Local plastic deformation effects on the critical current of high-J$_{c}$ Nb$_{3}$Sn strands under uniaxial strain
/ Liu, Yunhao (Hefei, CUST) ; Sun, Yi (Hefei, CUST) ; Gao, Peng (Hefei, CUST) ; Nijhuis, Arend (Twente U., Enschede) ; Devred, Arnaud (CERN) ; Guo, Zichuan (Hefei, CUST) ; Zhu, Huajin (Guangxi Normal U.) ; Xu, Peng (Hefei, CUST) ; Shi, Yi (Hefei, CUST) ; Liu, Fang (Hefei, CUST)
In order to meet the target operating parameters of the toroidal field coils (TFCs) for the next-generation Chinese compact burning plasma tokamak, high critical current density (J$_{c}$) Nb$_{3}$Sn strand will be applied to the high-field winding-package of the TFC. To improve the transverse stiffness of the cable in withstanding the huge Lorentz force and avoiding conductor performance degradation, the short-twist-pitch and copper-wound-strand cable patterns were taken into consideration.

Critical current density of Nb$_{3}$Sn wires after irradiation with 65MeV and 24GeV protons
/ Spina, T (CERN) ; Scheuerlein, C (CERN) ; Richter, D (CERN) ; Bottura, L (CERN) ; Ballarino, A (CERN) ; Flükiger, R (CERN)
Industrial Nb$_{3}$Sn wires with Ti and Ta additives (RRP process) and with Ta additives (PIT process) with a diameter of 1 mm have been irradiated at room temperature with protons of 65 MeV and of 24 GeV at various fluences up to 1×1021 p/m2. A steady increase of Jc vs. [...]
