Advanced examination of Nb$_{3}$Sn coils and conductors for the LHC luminosity upgrade: a methodology based on computed tomography and materialographic analyses
/ Santillana, I Aviles (CERN) ; Sgobba, S (CERN) ; Crouvizier, M D (CERN) ; Devred, A (CERN) ; Izquierdo, G Arnau (CERN) ; Bulat, B (CERN) ; Moros, A (CERN) ; Izquierdo Bermudez, S (CERN) ; Milanese, A (CERN) ; Savary, F (CERN) et al.
The future of particle accelerators is strongly linked to the development of high—field magnets. The European Organization for Nuclear Research (CERN) is currently developing Nb$_{3}$Sn-based magnets for the high-luminosity upgrade of the large hadron collider (HL-LHC), to fully exploit its potential and surpass the intrinsic performance limitations of Nb–Ti-based magnets.

Analysis of the Leakage Events in the Thermal Shield Cooling Pipes of the ITER Magnet System
/ Sgobba, Stefano (CERN) ; Santillana, Ignacio Aviles (CERN) ; Celuch, Michal (CERN) ; Crouvizier, Mickaël (CERN) ; Perez Fontenla, Ana Teresa (CERN) ; Castro, Enrique Rodriguez (CERN) ; Mitchell, Neil (Euratom, St. Paul Lez Durance) ; Koizumi, Norikiyo (Euratom, St. Paul Lez Durance) ; Pearce, Robert (Euratom, St. Paul Lez Durance) ; Worth, Liam (Euratom, St. Paul Lez Durance) et al.
The ITER Thermal Shields (TS) consist of actively cooled stainless steel panels. Their role is to minimise the radiation heat load from warm components, such as the Vacuum Vessel (VV) and the cryostat, hence contributing to insulating the magnet system operating at 4.5 K. [...]

Status of the MQXFB Nb$_3$Sn quadrupoles for the HL-LHC
/ Izquierdo Bermudez, Susana (CERN) ; Ambrosio, Giorgio (Fermilab) ; Apollinari, Giorgio (Fermilab) ; Ballarino, Amalia (CERN) ; Barth, Christian (CERN) ; Crouvizier, Mickael Denis (CERN) ; Duarte Ramos, Delio (CERN) ; Devred, Arnaud (CERN) ; Feher, Sandor (Fermilab) ; Felice, Helene (CERN) et al.
The cold powering test of the first two prototypes of the MQXFB quadrupoles (MQXFBP1, now disassembled, and MQXFBP2), the Nb3Sn inner triplet magnets to be installed in the HL-LHC, has validated many features of the design, such as field quality and quench protection, but has found performance limitations. In fact, both magnets showed a similar phenomenology, characterized by reproducible quenches in the straight part inner layer pole turn, with absence of training and limiting the performance at 93% (MQXFBP1) and 98% (MQXFBP2) of the nominal current at 1.9 K, required for HL-LHC operation at 7 TeV.

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. [...]
