Nb$_3$Sn RRP Strand and Rutherford Cable Development for a 15 T Dipole Demonstrator
/ Barzi, E. (Fermilab) ; Andreev, N. (Fermilab) ; Li, P. (Fermilab) ; Lombardo, V. (Fermilab) ; Turrioni, D. (Fermilab) ; Zlobin, A. V. (Fermilab)
Keystoned Rutherford cables made of 28 strands and with a stainless steel core were developed and manufactured using 1-mm Nb$_3$Sn composite wires produced by Oxford Superconducting Technology with 127 and 169 restacks using the Restacked-Rod-Process. The performance and properties of these cables were studied to evaluate possible candidates for 15-T accelerator magnets..

/HighFled Magnets Collaboration
Fermi National Accelerator Laboratory has been developing a 15-T Nb$_3$Sn dipole demonstrator for a future very high energy pp collider based on an optimized 60-mm aperture four-layer “cos-theta” coil. To increase the magnet efficiency, the coil was graded by using two cables with same 15 mm width and different thicknesses made of two different restacked rod process (RRP) wires. [...]

Test Results of the First 3.7 m long Nb$_3$Sn Quadrupole by LARP and Future Plans
/ LARP Collaboration
In December 2009 during its first cold test, LQS01, the first Long Nb$_3$Sn Quadrupole made by LARP (LHC Accelerator Research Program, a collaboration of BNL, FNAL, LBNL and SLAC), reached its target field gradient of 200 T/m. This target was set in 2005 by the US Department of Energy, CERN and LARP, as a significant milestone toward the development of Nb$_3$Sn quadrupoles for possible use in LHC luminosity upgrades. [...]

The US LHC Accelerator Research Program (LARP) is developing Nb$_3$Sn accelerator magnet technology for the LHC luminosity upgrade. Two 90 mm "Technology Quadrupole" models (TQS01, TQC01) are being developed in close collaboration between LBNL and FNAL, using identical coil design, but two different support structures [...]

In 2004, the US DOE established the LHC Accelerator Research Program (LARP) with the goal of developing a technology base for future upgrades of the LHC. The focus of the magnet program, which is a collaboration of three US laboratories, BNL, FNAL and LBNL, is on development of high gradient quadrupoles using Nb$_3$Sn superconductor [...]

Construction and Test of 3.6 m Nb$_3$Sn Racetrack Coils for LARP

Development of high-performance Nb$_3$Sn quadrupoles is one of the major goals of the LHC Accelerator Research Program (LARP). As part of this program, long racetrack magnets were made in order to check the fabrication steps for long Nb$_3$Sn coils, that the changes in coil length that take place during reaction and cooldown are correctly accounted for in the quadrupole design, and the use of a long aluminum shell for the support structure.

Fermilab and CERN started the development of 11 T Nb$_3$Sn dipoles 11 m long to replace a few regular LHC NbTi dipoles and free space for cold collimators in LHC dispersion suppression (DS) areas. An important step in the design of these magnets is the development of the high aspect ratio Nb$_3$Sn cable to achieve the nominal field of 11 T at the nominal LHC operating current of 11.85 kA with 20% margin.
