Design Study of 2-in-1 Large Aperture IR Dipole (D2) for the LHC Iuminosity Upgrade

摘要

This paper analyses possible D2 magnet designs for the dipole-first option of the LHC luminosity upgrade based on Nb3Sn superconductor and compares them in terms of the maximum field, field quality, and Lorentz forces in the coils.
