Measurement and correction of focusing errors is of great importance for performance and
machine protection of circular accelerators. Furthermore LHC needs to provide equal …

Abstract During LHC Run 2, the LHC machine configuration evolved significantly. Starting
from a very careful approach in 2015, with the priority on stability and ease of …

In 2017, optics commissioning strategy for low-β* operation of the CERN Large Hadron
Collider (LHC) underwent a major revision. This was prompted by a need to extend the …

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 …

Accurate measurements of optics functions, β, α, D, are essential for proper operation of a
synchrotron both for machine protection and for performance. β functions can be obtained …

Optics control in the HL-LHC will be challenged by a very small β* of 15 cm in the two main
experiments. HL-LHC physics fills will keep a constant luminosity during several hours via β …

Abstract In 2015 the Large Hadron Collider (LHC) restarted for Run 2 after a two year long
shutdown to consolidate the machine for operation at nominal beam energy. Following a few …
