Towards MQXFB Series Coils
/ Lusa, Nicholas (CERN) ; Devred, Arnaud (CERN) ; Ferradas Troitino, José (CERN) ; Izquierdo Bermudez, Susana (CERN) ; Milanese, Attilio (CERN) ; Quassolo, Penelope Matilde (CERN) ; Straarup, Simon (CERN) ; Todesco, Ezio (CERN)
The cold powering test of the first two MQXFB prototype quadrupoles, the Nb$_3$Sn inner triplet magnets to be installed in the HL-LHC, has found performance limitations. This prompted putting on hold the coil fabrication, to review in depth the full manufacturing process, while in parallel performing destructive inspections on selected coils. [...]

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.

Progress in the Development of the Nb$_3$Sn MQXFB Quadrupole for the HiLumi Upgrade of the LHC
/ Izquierdo Bermudez, Susana (CERN) ; Ambrosio, Giorgio (Fermilab) ; Apollinari, Giorgio (Fermilab) ; Bajko, Marta (CERN) ; Bordini, Bernardo (CERN) ; Bourcey, Nicolas (CERN) ; Duarte Ramos, Delio (CERN) ; Ferracin, Paolo (LBL, Berkeley) ; Fiscarelli, Lucio (CERN) ; Feher, Sandor (Fermilab) et al.
The high-luminosity upgrade of the Large Hadron Collider (HL-LHC) requires new high field and large-aperture quadrupole magnets for the low-beta inner triplets (MQXF). With a nominal operating gradient of 132.2 T/m in a 150 mm aperture and a conductor peak field of 11.3 T, the new quadrupole magnets are based on Nb3Sn superconducting technology. [...]

Polarization and Centre-of-mass Energy Calibration at FCC-ee
/ Blondel, Alain (Geneva U. ; CERN ; Paris U., VI-VII) ; Janot, Patrick (CERN) ; Wenninger, Jörg (CERN) ; Aßmann, Ralf (DESY) ; Aumon, Sandra (CERN) ; Azzurri, Paolo (INFN, Pisa) ; Barber, Desmond P. (DESY) ; Benedikt, Michael (CERN) ; Bogomyagkov, Anton V. (Novosibirsk, IYF) ; Gianfelice-Wendt, Eliana (Fermilab) et al.
The first stage of the FCC (Future Circular Collider) is a high-luminosity electron-positron collider (FCC-ee) with centre-of-mass energy ranging from 88 to 365 GeV, to study with high precision the Z, W, Higgs and top particles, with samples of $5 \times 10^{12}$ Z bosons, $10^8$ W pairs, $10^6$ Higgs bosons and $10^6$ top quark pairs.
