/ Araujo, D M (PSI, Villigen) ; Auchmann, B (PSI, Villigen ; CERN) ; Brem, A (PSI, Villigen) ; Daly, M (PSI, Villigen) ; Hug, C (PSI, Villigen) ; Michlmayr, T (PSI, Villigen) ; Amm, K (Brookhaven Natl. Lab.) ; Anerella, M (Brookhaven Natl. Lab.) ; Yahia, A Ben (Brookhaven Natl. Lab.) ; Cozzolino, J (Brookhaven Natl. Lab.) et al.
In the context of high-energy physics, the use of Nb3Sn superconducting magnets as a cost-effective and reliable technology depends on improvements in the following areas: long development and manufacturing cycles, conductor degradation after thermal cycling, long training, as well as a demonstration in accelerator magnets with a beam aperture of the full potential of modern Nb3Sn conductors. In short, performance, robustness, and cost are the three issues to be addressed. [...]

In support of the luminosity upgrade of the Large Hadron Collider (LHC), the US LHC Accelerator Research Program (LARP) has been developing a 1-meter long, 120 mm bore Nb$_3$Sn IR quadrupole magnet (HQ). With a short sample gradient of 219 T/m at 1.9 K and a conductor peak field of 15 T, the magnet will operate under higher forces and stored-energy levels than that of any previous LARP magnet models.
