A1 - Superconducting Accelerator Magnets

Regular 15 minutes Oral Presentation

The LHC Accelerator Research Program (LARP), in collaboration with CERN and under the scope of the high luminosity upgrade of the Large Hadron Collider, is in the prototyping stage of the development of a 150 mm aperture high-field Nb3Sn quadrupole magnet called MQXF. This magnet is mechanically supported using a shell-based support structure, which has been extensively demonstrated on...

Regular 15 minutes Oral Presentation

The development of Nb3Sn quadrupole magnets for the High-Luminosity LHC upgrade is a joint venture between the US LHC Accelerator Research Program (LARP) and CERN with the goal of fabricating large aperture quadrupoles for the LHC interaction regions (IR). The inner triplet (low-β) NbTi quadrupoles in the IR will be replaced by the stronger Nb3Sn magnets boosting the LHC program of having...

Regular 15 minutes Oral Presentation

For the luminosity upgrade of the Large Hadron Collider at CERN, the installation of new generation of lower beta* quadrupole magnets is foreseen on each side of the ATLAS and CMS experiment insertions zones. The new magnets are based on Nb3Sn technology and designed to achieve a field gradient of 132.6 T/m within a 150-mm aperture reaching a peak field of 11.4 T at the conductor level. In...

Regular 15 minutes Oral Presentation

In the framework of the High-Luminosity upgrade of the Large Hadron Collider, the US LARP collaboration and CERN are jointly developing a 150 mm aperture Nb3Sn quadrupole for the LHC interaction regions. Due to the large beam size and orbit displacement in the final focusing triplet, MQXF has challenging targets for field quality at nominal operation conditions. Three short model magnets have...

Regular 15 minutes Oral Presentation

The US LARP (LHC Accelerator Research Program), in collaboration with CERN, has started developing prototypes of the low-beta Quadrupoles (MQXF) for the High Luminosity Upgrade of the LHC at CERN. These large aperture (150 mm) high gradient (133 T/m) quadrupoles will use Nb3Sn conductor to replace the present 70-mm aperture NbTi quadrupoles.
The first LARP prototype (MQXFA1) has coils with 4...

Regular 15 minutes Oral Presentation

High Energy LHC is a study aimed at exploring the possibility to upgrade the present LHC ring to reach 25 TeV total collision energy which requires 16 Tesla dipoles. Upon the conclusion of the High Luminosity Upgrade, the US LHC Accelerator Research Program in collaboration with CERN will have extensive Nb₃Sn magnet fabrication experience. This experience includes robust...
