Room: Zoom Comments on MDs: - MD9325 Beam halo population - MD11843: Collimation performance with HL-LHC settings - MD6925: Electron cloud coupled-bunch tune shifts at injection - MD12743: RF power limitations for high-intensity batches - MD12805: Impact of longitudinal impedance and betatron coupling on the Schottky spectrum

MD12663: Wire compensation during the beta*-leveling

• Guido Sterbini (CERN)

Room: Zoom - Loss maps to be done before. When and approval of it? - Why does the PCinterlock of the wire need to be masked at 30 cm only? Is this ok with that many bunches? - Clarify the order of loss maps, change of collimator settings, change of wire settings and scraping. - Masking of interlocks to be defined for each step.

MD12723: HL-LHC optics cycle (part II)

• Rogelio Tomas Garcia (CERN)
• Riccardo De Maria (CERN)
• Tobias Hakan Bjorn Persson (CERN)

Room: Zoom - Clarify number of pilots and total intensity for validation - Specify tools to be used for optics measurements (AC-dipole etc.) - Third ramp with loss maps, can take two nominals and pilots to stay below 3e11 total. However, aperture checks with nominals is risky.

MD12844: Faser background mitigations

• Bjorn Hans Filip Lindstrom (University of London (GB))

Room: Zoom - Clarify the masking in the procedures, including collimator threshold. - Detail the rotation of the crossing angle, including which tools to be used. - Change of beam flags and interlocks should be YES
