Title: Progress on high luminosity LHC Nb$$_{3}$$Sn magnets

Abstract

The HL-LHC project aims at allowing to increase the collisions in the Large Hadron Collider by a factor ten in the decade 2025 - 2035. One essential element are the superconducting magnets around the interaction region points, where large aperture magnets will be installed to allow to further reduce the beam size in the interaction point. The core of this upgrade is the Nb$$_{3}$$Sn triplet, made of 150 mm aperture quadrupoles of in the range of 7 - 8 m. The project is being shared between CERN and US Accelerator Upgrade Program, based on the same design, and on two strand technologies. The project is ending the short model phase, and entering the prototype construction. We will report on the main results of the short model program, including quench performance and field quality. A second important element is the 11 T dipole that replacing a standard dipole makes space for additional collimators. The magnet is also ending the model development and entering the prototype phase. A critical point in the design of this magnet is the large current density, allowing increasing the field from 8 to 11 T with the same coil cross - section as in the LHC dipoles. This is also the first two - in - one Nb$$_{3}$$Sn magnet developed so far. We will report the main results on the test and the critical aspects .
