With the successful test of the first two pre-series magnets the US HL-LHC Accelerator Upgrade Project has started production of the MQXFA magnets to be used in Q1/Q3 inner triplet elements of the HL-LHC. This good start comes after the test of two prototypes with limited performance, and it demonstrates the importance of learning from past issues. [...]

The HL-LHC Low-$\beta$ Quadrupole Magnet MQXF: from Short Models to Long Prototypes
/ Ferracin, Paolo (CERN) ; Ambrosio, Giorgio (Fermilab) ; Anerella, Michael (Brookhaven) ; Bajas, Hugues (CERN) ; Bajko, Marta (CERN) ; Bordini, Bernardo (CERN) ; Bossert, Rodger (Fermilab) ; Bourcey, Nicolas (CERN) ; Cheng, Daniel W (LBL, Berkeley) ; Chlachidze, Guram (Fermilab) et al.
Among the components to be upgraded in LHC inter- action regions for the HiLumi-LHC projects are the inner triplet (or low-β) quadrupole magnets, denoted as Q1, Q2a, Q2b, and Q3. The new quadrupole magnets, called MQXF, are based on Nb3 Sn superconducting magnet technology and operate at a gradient of 132.6 T/m, with a conductor peak field of 11.4 T. [...]
