Abstract | Luminosity levelling by β∗ is the baseline scenario for HL-LHC and will possibly be used in 2018 LHC operation. In this MD, we commissioned a novel controls approach to β∗ levelling using improved LSA trims and automatic orchestration. Compared to the regular squeeze using sequences, this approach is aimed to be minimally invasive to LHC operation in Stable Beams. Using this tool, we demonstrated the feasibility of β∗ levelling between 1 m and 30 cm. |
