DESIGN STUDY OF 2-IN-1 LARGE-APERTURE IR DIPOLE (D2) FOR THE LHC LUMINOSITY UPGRADE

摘要

This paper analyses possible D2 magnet designs for the "dipole-first" option of the LHC luminosity upgrade based on Nb{sub}3Sn superconductor and compares them in terms of the maximum field, field quality, and Lorentz forces in the coils.
