/ Todesco, Ezio (CERN) ; Annarella, M (Brookhaven) ; Ambrosio, Giorgio (Fermilab) ; Apollinari, Giorgio (Fermilab) ; Ballarino, Amalia (CERN) ; Bajas, H (CERN) ; Bajko, Marta (CERN) ; Bordini, Bernardo (CERN) ; Bossert, R (Fermilab) ; Bottura, Luca (CERN) et al.
The HL-LHC project aims at allowing to increase the collisions in the Large Hadron Collider by a factor ten in the decade 2025 - 2035. One essential element are the superconducting magnets around the interaction region points, where large aperture magnets will be installed to allow to further reduce the beam size in the interaction point.

The High Luminosity (HiLumi) Large Hadron Collider (LHC) project has, as the main objective, to increase the LHC peak luminosity by a factor five and the integrated luminosity by a factor ten. This goal will be achieved mainly with a new interaction region layout, which will allow a stronger focusing of the colliding beams. [...]

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. [...]

Critical Current Measurements Under Transverse Pressure of a Nb3Sn Rutherford Cable Based on 1 mm RRP Wires
/ Duvauchelle, Jean-Eudes (CERN) ; Bordini, Bernardo (CERN) ; Fleiter, Jérôme (CERN) ; Ballarino, Amalia (CERN)
In order to achieve higher magnetic fields and/or larger magnet apertures, next generation accelerator magnets will be based on high-$J_{c}$ Nb$_{3}$Sn Rutherford cables. For the HighLuminosity LHC project, CERN is manufacturing dipole and quadrupole magnets based on state-of-the-art high-$J_{c}$ Nb$_{3}$Sn superconductor. [...]

The quadrupole magnets for the LHC upgrade to higher luminosity are jointly developed by CERN and US-LARP (LHC Accelerator Research Program). These Nb3Sn magnets will be protected against overheating after a quench by a combination of heaters bonded to the coil outer surface and CLIQ (Coupling-Loss Induced Quench) units. [...]

In support of the development of a large-aperture Nb$_3$Sn superconducting quadrupole for the Large Hadron Collider (LHC) luminosity upgrade, several two-layer technological quadrupole models of TQC series with 90 mm aperture and collar-based mechanical structure have been developed at Fermilab in collaboration with LBNL. This paper summarizes the results of fabrication and test of TQC02a, the second TQC model based on RRP Nb3Sn strand, and TQC02b, built with both MJR and RRP strand. [...]
