LHC Run 2 optics commissioning experience in view of HL-LHC

LHC Run 2 has achieved a $\beta^*$ lower than a factor 2 below design. This has significantly challenged optics measurement and correction techniques in the linear and non-linear regimes, leading to the development of new approaches. Furthermore, experimenting a large variety of optics has allowed f...

Descripción
Sumario:LHC Run 2 has achieved a $\beta^*$ lower than a factor 2 below design. This has significantly challenged optics measurement and correction techniques in the linear and non-linear regimes, leading to the development of new approaches. Furthermore, experimenting a large variety of optics has allowed facing the difficulties of future optics and gaining understanding of the machine imperfections. A summary of these aspects is given in view of their implications for the HL-LHC Project.
