Description

RP optics, crossing planes, flat optics, consider the use of flat optics either for necessity in the HV crossing configuration or for performance in the current VH configuration (e.g. 30/20cm). Further improvements: reducing the xing angle at the end of leveling? + wire …?
E-cloud modelling and heat-load in cold magnets (only impact on performance 2025-HL, confirmed trend from previous years?)
Optimal filling scheme
BCMS vs STD (only impact on: which one give us longer levelling?)
usage of the BBLR wires
optimal filling time and lumi predictions
What can / should be tested ‘transparently’ before LS3 to prepare HL-LHC era (incl. intensity limits)?
