Luminosity leveling in python/cpymad

• Guido Sterbini (CERN)

Room: 6/R-012 - conference room Presently the luminosity leveling in (HL-)LHC mask is performed using the BB macros of MAD-X. Typically, the leveling is adopted only in IP8 and consists in a separation leveling. After a review of the luminosity formula, we show how, with a pythonic approach, we can generalize this workflow.

Wires knobs in the Run3 Optics

• Axel Poyet (Universite Grenoble-Alpes (FR))

Room: 6/R-012 - conference room The status of the wire Q-feed-forward knobs for Run3 will be presented. After reviewing the dipole-quadrupole effects (in open loop, i.e., no feed-forward) at injection (B1+B2), we analyze it at top energy (e.g., ATS at $\beta^*=30$ cm). Then we show the impact of the proposed 4 knobs (2 knobs for each beam) on the Q, beta-beating, chromaticity, dispersion (etc...) as function of the ATS tele-index as function of the TCT opening and the wire current.
