Title: Correction of high gradient quadrupole harmonics with magnetic shims

Abstract

Superconducting quadrupole magnets with 70 mm aperture and nominal field gradient of 215 T/m are being developed by the US-LHC Accelerator Project for the Interaction Regions of the Large Hadron Collider. Due to large beam size and orbit displacement in the final focusing triplet, these magnets are subject to stringent field quality requirements. For this reason, a correction scheme based on magnetic shims was investigated. This paper reports design calculations, fabrication issues and tests results involving magnetic shims.
