Title: High Field Superconducting Magnets for Future Colliders

Speaker: GianLuca Sabbi（Lawrence Berkeley National Laboratory）

Moderator: Prof. LOU Xinchou

Place: Room C305, IHEP Main Building

Abstract：

Intensive magnet R&D efforts are underway to meet the requirements of future colliders and enable new discoveries in High Energy Physics. During the next decade, a series of LHC upgrades will be implemented aiming at a 10-fold increase of the integrated luminosity with respect to the original design. Starting in 2004, the US LHC Accelerator Research Program has developed large aperture Nb3Sn quadrupoles for this application. At this time, the program is completing the R&D phase and transitioning toward prototyping and production. Future colliders significantly expanding the energy reach of LHC are also under study, and new magnet technologies will be required to support the objectives of these projects. A review of progress to date and future challenges is presented.

About the speaker：

GianLuca Sabbi received his Doctoral Degree in 1995, with a Thesis on beam instabilities at CERN’s Large Electron Positron collider (LEP). From 1996 to 2000, he held an Associate Scientist position at Fermilab, where he contributed to the design and prototyping of the MQXB IR quadrupoles for LHC. He then joined the superconducting magnet program at Berkeley National Laboratory, where he led the development of high field dipoles for future high energy colliders. From 2009 to 2013, he coordinated the LARP magnet R&D effort, a collaboration of US National Laboratories developing Nb3Sn IR Quadrupoles for the LHC luminosity upgrade. He is currently the co-leader of the magnet work package for the High Luminosity LHC project.
