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.
