    • 10:20 10:30
      MD9523: Threshold of longitudinal loss of Landau damping and MD9525: Injection power transients with different RF settings 10m

      MD9523: Threshold of longitudinal loss of Landau damping
      - Confirm maximum desired bunch intensity (3e11 according to current procedure)
      - Check ADT bunch intensity limit and max. bunch intensity that can be injected
      - Clarify required RF interlock masking and update procedure accordingly

      MD9525: Injection power transients with different RF settings
      - Requested 1000 bunches with bunch intensity of 2e11 (beyond operationally achieved values): Injection set-up? Max. number of bunches?

      Speaker: Helga Timko (CERN)

      MD6923: Slow beam degradation from incoherent electron cloud effects on the 3Qy resonance 10m
      • Clarify max. number of bunches (3x72b or 600b)
      • Max. allowed beta beat?
      • Clarify "Optionally, retract TDIS to minimize losses on it."
      • Put explicitly the optics collimator sequence to be used
      Speaker: Konstantinos Paraschou (CERN)
    • 10:40 10:50
