The high-luminosity Large Hadron Collider (HL-LHC) upgrade project aims to increase the LHC peak luminosity up to 5×10^34 cm^-2s^-1 and the integrated luminosity up to3000 fb^-1. To achieve this goal, the quadrupole and dipole magnets around the two interaction points, i.e., the ATLAS and the CMS, will be upgraded. [...]

The High Energy Accelerator Research Organization (KEK) has been developing the beam separation dipole magnet for the High Luminosity Large Hadron Collider (HL-LHC) upgrade. The magnet has a coil aperture of 150 mm, using Nb-Ti superconducting cable, and a dipole magnetic field of 5.6 T will be generated at 12 kA, at 1.9 K, to provide the field integral of 35 T·m. [...]

In this section we present the magnet technology for the High Luminosity LHC. After a short review of the project targets and constraints, we discuss the main guidelines used to determine the technology, the field/gradients, the operational margins, and the choice of the current density for each type of magnet.

Field Quality and Mechanical Analysis of the Beam Separation Dipole for HL-LHC Upgrade
/ Sugano, Michinaka ; Nakamoto, Tatsushi ; Xu, Q (KEK, Tsukuba) ; Kawamata, H (KEK, Tsukuba) ; Todesco, Ezio (CERN)
High luminosity upgrade of the Large Hadron Collider (HL-LHC) project has been launched to attain a ten times higher integrated luminosity than the current LHC that has been in operation for over ten years. For this goal, the quadruple and dipole magnets around two interaction points, the ATLAS and the CMS, will be upgraded. [...]

The High-Luminosity Large Hadron Collider upgrade (LHC) project aims to increase the peak luminosity of the LHC to 5 ×10^34 cm ^- 2s ^- 1, and a total integrated luminosity of 3000 fb ^- 1 from 2020 to 2030 by upgrading the low-beta insertion system for the ATLAS and CMS experiments. The aperture of the insertion magnets including the focusing/defocusing quadrupoles and separation dipoles will be doubled to achieve a smaller β*. [...]
