Description
Insertion quadrupoles with large aperture and high gradient are required to achieve the luminosity upgrade goal of 1035 cm-2 s-1 at the Large Hadron Collider. In 2003, the US Department of Energy established the LHC Accelerator Research Program (LARP) to address key technical challenges associated with the upgrade. LARP is a collaboration of Brookhaven National Laboratory, Fermilab, Lawrence Berkeley National Laboratory, and the SLAC National Accelerator Laboratory, working in close coordination with CERN. The focus of the magnet R&D effort is on development of advanced IR quadrupoles using Nb3Sn in order to operate at high field and with sufficient temperature margin. Program components address technology issues including conductor and cable development, coil and structure fabrication, quench performance, field quality and alignment, length scale-up, and quench protection. The main accomplishments of the magnet R&D program to date will be reviewed, and plans to complete the technology demonstration and prepare for magnet production will be presented.
