The US-LHC accelerator research program (LARP) built and tested the first 3.7-m long Nb$_3$Sn quadrupole model of LQ series with a 90 mm bore diameter and a target field gradient of 200 T/m. The LQ series, developed in collaboration among FNAL, LBNL and BNL, is a scale up of the previously tested 1-m long technology quadrupoles of TQ series based on similar coils and two different mechanical structures (shell-based TQS and collar-based TQC), with a primary goal of demonstrating the Nb$_3$Sn accelerator magnet technology for the luminosity upgrade of LHC interaction regions.

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. [...]

Lab.) ; Dietderich, D R (LBNL, Berkeley) ; Escallier, J (Brookhaven Natl. Lab.) et al.
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.
