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...
The US High-Luminosity LHC Accelerator Upgrade Project (AUP) is responsible for delivering cryo-assemblies for the Q1/Q3 quadrupole optical components of the High Luminosity LHC upgrade at CERN. Total of 10 cryo-assemblies containing two Nb3Sn quadrupole magnets per cold mass will be delivered within this program. After the successful test of the first pre-series cryo-assembly in 2023, two...
The High-Luminosity upgrade of the LHC at CERN requires 32 new cryo-assemblies to be installed around the interaction points 1 and 5. They incorporate 90 magnets of various types, and in addition several prototypes and spares are built. The magnets are produced within the HL-LHC project, and a large part is tested at CERN. Most of the magnets are tested first in standalone configuration in a...
The High-Luminosity LHC (HL-LHC) upgrade aims to increase the colliders integrated luminosity by an order of magnitude through significant modifications to the interaction region layout. One of the key hardware components involved in this upgrade is the MBRD combination-recombination dipole, a double-aperture magnet with magnetic fields aligned in both bores. For this magnet, a magnetic field...
MCBXF magnets are orbit correctors for the High-Luminosity (HL) Large Hadron Collider (LHC) upgrade. The magnet design consists of two nested dipoles, with an aperture of 150 mm. The magnets have been designed in two physical lengths, namely of 2.5 m (MCBXFA) and 1.5 m (MCBXFB), with the same cross section. The series production of the magnets consists of 6 long and 11 short magnets and being...
KEK have so far tested four series beam separation dipoles, a.k.a. D1 (MBXF) magnets, for the High Luminosity LHC upgrade (HL-LHC). The magnet is wound on Nb-Ti Rutherford cables and designed to operate at 1.9 K generating a central field of 5.6 T with a magnetic length of 6.3 m, which corresponds to a field integral of 35 Tm. All the series magnets were subjected to a quench training campaign...
The production of the MQXFA low-beta quadrupole magnets for the High Luminosity LHC (HL-LHC) is quite advanced with about 20 magnets cold tested in a vertical cryostat. The MQXFA magnets are fabricated by the US HL-LHC Accelerator Upgrade Project (AUP) and are being used in the Q1 and Q3 Inner Triplet (IT) elements of the HL-LHC, whereas CERN is fabricating similar magnets for Q2a and Q2b IT...
