New local optics measurements and correction techniques for the LHC and its luminosity upgrade / Coello de Portugal, J (CERN) ; Tomás, R (CERN) ; Hofer, M (CERN)
As the beams at the interaction points (IPs) of circular colliders are pushed toward smaller sizes, the correction of the magnetic field errors in high-β regions become increasingly important, but also challenging. This paper presents an algorithm developed to compute automatically local corrections. [...]
