    The U.S. High-Luminosity LHC Accelerator Upgrade Project (HL-LHC AUP) team is fabricating the 4.5 m long MQXFA magnets, a 150 mm aperture high-field Nb3Sn low-β quadrupole magnet, in the context of the CERN Hi-Luminosity LHC (HL-LHC) upgrade. To date, two prototype magnets and five Pre-Series magnets have been assembled and tested. The first two prototypes did not achieve full performance...

    As part of the U.S. contribution to the HL-LHC Accelerator Upgrade Project (AUP), Fermilab is designing and building cold masses suitable for use in the LHC interaction regions. The cold mass provides a vacuum-tight helium enclosure for the magnets. Two magnets are aligned both axially and in cross section at Fermilab based on survey and warm magnetic measurements. Bus work and...

    Abstract— Fermilab is fabricating ten full length cold masses for the high-luminosity Large Hadron Collider Accelerator Upgrade Project (HL-LHC AUP). One practice assembly and one pre-series assembly have been completed. This paper summarizes the construction details. Topics include incoming inspection, bus assembly, component machining, shell forming, beam tube insertion, bus expansion loop...

    Cryo-assemblies with the low-beta Nb3Sn quadrupoles for the high luminosity LHC (HL-LHC) upgrade will be tested at Fermilab’s magnet test facility. Total of 10 cryo-assemblies will be delivered to CERN within the US HL-LHC Accelerator Upgrade Project (AUP). The horizontal test stand at Fermilab already has been used for testing the existing LHC inner-triplet quadrupoles, but the stand and...

    Poster

    The High Luminosity LHC (HL-LHC) Project is planning to install 16 cold-masses, made with the Nb3Sn quarupole magnets, in the LHC Interaction Regions to significantly increase its luminosity. Half of these cold masses are fabricated at BNL, FNAL, and LBNL under the US Accelerator Research Program (AUP). Each cold mass includes two identical Nb3Sn quadrupole magnets, called MQXFA, each with a...

    Poster

    For the Hi-Lumi LHC Upgrade (HL-LHC) new high field and large-aperture quadrupole magnets for the low-beta inner triplets (Q1, Q2, Q3) are being built. These new quadrupole magnets are based on Nb3Sn superconducting technology. As part of the US-HiLumi Accelerator Upgrade Project (AUP) ten Cryostat Assemblies (LQXFA) for Q1 and Q3 replacement will be built, tested and delivered to CERN. The...
