Description
The goal of the LHC IR Upgrade Phase-1 is to provide more flexibility for
focusing of the LHC beams in the ATLAS and CMS high luminosity insertions and to enable reliable operation of the collider at a luminosity above the nominal 1034 cm-2s-1. This improvement is achieved by replacing the present low-b triplets and D1 separation dipoles in these two insertions with new magnets having a considerably larger aperture. The magnets are built using the mature technology of Nb-Ti superconductors cooled at 1.9 K. A brief status of the project is given, and the boundary conditions (technical, budgetary and planning) are reviewed.
