Abstract

The High Luminosity upgrade of the Large Hadron Collider (HL-LHC) at CERN will include eight cryo-assemblies that are expected to be fabricated and delivered to CERN by the US HL-LHC Accelerator Upgrade Project (AUP) as part of the U.S. contributions to the HL-LHC. These cryostat assemblies are the quadrupole magnetic components of the HL-LHC Q1 and Q3 inner triplet optical elements in front of the two interaction points. Each cryo-assembly consists of two 4.2 m long Nb₃Sn quadrupole magnets with aperture 150 mm and operating gradient 132.6 T/m. The first pre-series cryo-assembly has been fabricated and successfully tested at the horizontal test facility at Fermi National Accelerator Laboratory. Here in this manuscript we report the quench test results of the LQXFA/B-01 cryo-assembly. The primary objective of the horizontal test is full cryo-assembly qualification and validation of the performance requirements.

AUP first Pre-series Cold Mass Installation into the Cryostat

Conference Strauss, T. ; S. Feher a, S. a ; Rabehl, R. ; ...

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 first of the LQXFA was assembled and tested at Fermi National Accelerator Laboratory (FNAL) during the fall of 2022 and spring 2023. We will present the integration work of the Cold Mass assembly into the Cryostat Kit provided bymore »« less

Analysis of the short-to-ground event in the LARP-AUP MQXFAP1 magnet, and its implication on the production and tests of the series magnets

Journal Article Marinozzi, Vittorio ; Ambrosio, Giorgio ; Muratore, Joseph ; ... - TBD

Starting from 2022, the Large Hadron Collider (LHC) at CERN will be shut down to increase the luminosity of the machine. One of the main interventions will be inserting more performing low-β quadrupoles, called MQXF, in the interaction points. The US is involved in this activity with the US HL-LHC Accelerator Upgrade Project (AUP), and is responsible of the production and test of the Q1 and Q3 cryo-assemblies (each one containing two 4.2-m magnets in a single cold mass) of the triplet. After completing the US short model phase, the prototyping phase has started with MQXFAP1 (1st prototype, 4m long)more »« less

Magnetic Measurements of HL-LHC AUP Cryo-Assemblies at Fermilab

Conference DiMarco, J. ; Akella, P. ; Ambrosio, G. ; ...

LQXFA/B production series cryogenic assemblies are being built for the LHC upgrade by the HL-LHC Accelerator Upgrade Project (AUP). These contain a pair of MQXFA quadrupole magnets combined as a cold mass within a vacuum vessel, and are to be installed in the IR regions of the LHC. The LQXFA/B are being tested at 1.9 K to assess alignment and magnetic performance at Fermilab's horizontal test facility. The ~10 m - long assembly must meet stringent specifications for quadrupole strength and harmonic field integrals determination, magnetic axis location, and for variations in axis position and local field profile.
