/ Ambrosio, Giorgio (Fermilab) ; Amm, Kathleen (Brookhaven) ; Anerella, Michael (Brookhaven) ; Apollinari, Giorgio (Fermilab) ; Izquierdo, Gonzalo Arnau (CERN) ; Baldini, Maria (Fermilab) ; Ballarino, Amalia (CERN) ; Barth, Christian (CERN) ; Yahia, Anis Ben (Brookhaven) ; Blowers, James (Fermilab) et al.
By the end of October 2022, the US HL-LHC Accelerator Upgrade Project (AUP) had completed fabrication of ten MQXFA magnets and tested eight of them. The MQXFA magnets are the low beta quadrupole magnets to be used in the Q1 and Q3 Inner Triplet elements of the High Luminosity LHC. [...]

(PSI, Villigen) ; Balachandran, S. (Natl. High Mag. Field Lab.) ; Baldini, M. (Fermilab) ; Ballarino, A. (CERN) ; Barua, S. (Natl. High Mag. Field Lab.) et al.
Colliders are built on a foundation of superconducting magnet technology that provides strong dipole magnets to maintain the beam orbit and strong focusing magnets to enable the extraordinary luminosity required to probe physics at the energy frontier. [...]

Study of the Heater-Coil Electrical Insulation for the HL-LHC Low Beta Quadrupoles
/ Marinozzi, Vittorio (Fermilab) ; Ambrosio, Giorgio (Fermilab) ; Baldini, Maria (Fermilab) ; Izquierdo Bermudez, Susana (CERN) ; Ferracin, Paolo (LBL, Berkeley) ; Krave, Steven (Fermilab) ; Muratore, Joseph (BNL, NSLS) ; Nobrega, Alfred (Fermilab) ; Parker, Marcellus (Fermilab) ; Todesco, Ezio (CERN) et al.
In the framework of the HL-LHC project, the present LHC low-β superconducting quadrupoles will be substituted with higher performance Nb3Sn magnets (MQXF) with 11.4 T coil peak field. MQXF coils are impregnated with epoxy resin to reduce risk of stress concentration on the brittle conductor. [...]

Assessment of MQXF Quench Heater Insulation Strength and Test of Modified Design
/ Baldini, Maria (Fermilab) ; Ambrosio, Giorgio (Fermilab) ; Anerella, Michael D (Brookhaven) ; Bermudez, Susana I (CERN) ; Bossert, Rodger C (Fermilab) ; Ferracin, Paolo (LBL, Berkeley) ; Krave, Steven (Fermilab) ; Mangiarotti, Franco J (CERN) ; Marinozzi, Vittorio (Fermilab) ; Nobrega, Alfred (Fermilab) et al.
The HL-LHC interaction region magnet triplets (Q1,Q2, and Q3) will be composed of superconducting Nb3Sn quadru-poles. The MQXF quadrupole protection system is based on CLIQ (Coupling-Loss Induced Quench system) and outer layer quench heaters.This paper reports a summary of quench heaters to coil high voltage tests performed on MQXF short and long coils in air after fabrication, and in air and He gas after magnet training.

Intelliquench: An Adaptive Machine Learning System for Detection of Superconducting Magnet Quenches
/ Hoang, Duc (Rhodes Coll.) ; Boffo, Cristian (Fermilab) ; Tran, Nhan (Fermilab) ; Krave, Steven (Fermilab) ; Kazi, Sujay (MIT) ; Stoynev, Stoyan (Fermilab) ; Marinozzi, Vittorio (Fermilab)
In superconducting magnets, the irreversible transition of a portion of the conductor to resistive state is called a “quench.” Having large stored energy, magnets can be damaged by quenches due to localized heating, high voltage, or large force transients. Unfortunately, current quench protection systems can only detect a quench after it happens, and mitigating risks in Low Temperature Superconducting (LTS) accelerator magnets often requires fast response (down to ms) [...]

Lessons learned from the prototypes of the MQXFA Low Beta Quadrupoles for HL-LHC and status of production in the US
/ Ambrosio, Giorgio (Fermilab) ; Amm, Kathleen (BNL, NSLS) ; Anerella, Michael (BNL, NSLS) ; Apollinari, Giorgio (Fermilab) ; Baldini, Maria (Fermilab) ; Blowers, Jamie (Fermilab) ; Bossert, Rodger (Fermilab) ; Carcagno, Ruben (Fermilab) ; Cheng, Daniel W (BNL, NSLS) ; Chlachidze, Guram (Fermilab) et al.
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. [...]
