Challenges and Lessons Learned From Fabrication, Testing, and Analysis of Eight MQXFA Low Beta Quadrupole Magnets for HL-LHC
/ 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. [...]

Quench Protection of the First 4-m-Long Prototype of the HL-LHC Nb$_3$Sn Quadrupole Magnet
/ Ravaioli, E (LBL, Berkeley) ; Ambrosio, G (Fermilab) ; Bortot, L (CERN) ; Ferracin, P (CERN) ; Izquierdo Bermudez, S (CERN) ; Joshi, P (Brookhaven) ; Maciejewski, M (CERN) ; Marinozzi, V (Fermilab) ; Mentink, M (CERN) ; Muratore, J F (Brookhaven) et al.
/LARP
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. [...]

Test Results of LARP 3.6 m ${\rm Nb}_{3}{\rm Sn}$ Racetrack Coils Supported by Full-Length and Segmented Shell Structures

Lab.) ; Barzi, E (Fermilab) ; Bossert, R (Fermilab) ; Caspi, S (LBNL, Berkeley) ; Cheng, D W (LBNL, Berkeley) ; Cozzolino, J (Brookhaven Natl. Lab.) ; Dietderich, D R (LBNL, Berkeley) ; Escallier, J (Brookhaven Natl. Lab.) et al.
As part of the LHC Accelerator Research Program (LARP) to build a high performance quadrupole magnet with Nb$_3$Sn conductor, a pair of 3.6 m-long Nb$_3$Sn racetrack coils has been made at Brookhaven National Laboratory (BNL) and installed in two shell-type support structures built by Lawrence Berkeley National Laboratory (LBL). These magnet assemblies have been tested at 4.5 K at BNL to gauge the effect of extended length and prestress on the mechanical performance of the long structure compared to earlier short models.

Recent Test Results of the Fast-Pulsed 4 T COS$\Theta$ Dipole GSI 001
/ Moritz, G ; Kaugerts, J ; Escallier, John ; Ganetis, George ; Jain, Animesh K ; Marone, Andrew ; Muratore, Joseph F ; Thomas, Richard A ; Wanderer, Peter ; Auchmann, Bernard et al.
For the FAIR-project at GSI a model dipole was built at BNL with the nominal field of 4 T and a nominal ramp rate of 1 T/s. The magnet design was similar to the RHIC dipole with some changes for loss reduction and better cooling. [...]

Development of Superconducting Combined Function Magnets for the Proton Transport Line for the J-PARC Neutrino Experiments
/ Nakamoto, Tatsushi ; Ajima, Yasuo ; Anerella, Michael ; Escallier, John ; Fujii, T ; Fukui, Yuji ; Ganetis, George ; Gupta, Ramesh C ; Harrison, Michael ; Hashiguchi, E et al.
A second generation of long-baseline neutrino oscillation experiments has been proposed as one of the main projects at J-PARC jointly built by JAERI and KEK. Superconducting combined function magnets, SCFMs, will be utilized for the 50 GeV, 750 kW proton beam line for the neutrino experiment and an R&D; program is in underway at KEK. [...]

The Superconducting Magnet Division at Brookhaven National Laboratory (BNL) has made 20 insertion region dipoles for the Large Hadron Collider (LHC) at CERN. These 9.45 m-long, 8 cm aperture magnets have the same coil design as the arc dipoles now operating in the Relativistic Heavy Ion Collider (RHIC) at BNL and are of single aperture, twin aperture, and double cold mass configurations.
