Description
The LHC will resume operation in 2015 with an increased collision energy and new operational scenarios galore. Optics measurement and corrections will be challenged by dynamic beam processes as ramp & squeeze, collide & squeeze and beta* leveling. Furthermore the correction accuracy and the measurement resolution will continue to be challenged by the emittance measurement and the particle detectors requirements. This workshop aims at reviewing the status and progress in all fronts to ensure the high resolution measurement and correction for 2015. This review is within the HL-LHC and HighLumi framwork regarded as a general preparatory study for coming efficiently out of a long shutdown that features major machine modifications.
