Abstract :
Superconducting magnets built at the Brookhaven National Laboratory will be installed in both the Insertion Region IP2 and IP8, and the RF region of the Large Hadron Collider (LHC). In particular, field quality of these IR dipoles will become important during LHC heavy-ion operation when the β* at IP2 is reduced to 0.5 meters. This paper studies the impact of the magnetic errors in BNL-built magnets on LHC performance at injection and collision, both for proton and heavy-ion operation. Methods and schemes for error compensation are considered including optimization of magnet orientation and compensation using local IR correctors
