Description
At the heart of the High-Luminosity project (HL-LHC) of the CERN Large Hadron Collider (LHC), new low-beta* Nb$_3$Sn superconducting quadrupole magnets will be installed on each side of the ATLAS and CMS experiments. Half of these magnets are built by CERN and are called MQXFB. A total of 12 MQXFB magnets are being constructed: two to be installed in the IT String facility, for systems qualification; four to be installed in the LHC near ATLAS; four to be installed in the LHC near CMS, and two spare magnets. In the last two years, the first six MQXFB magnets have been tested and qualified up to nominal current in nominal operation conditions. In this paper we present the tests and analyze the magnets’ performance, with emphasis on qualification, non-conformity detection, and reliability evaluation.
