• Marc-André (ABP): Linear/non-linear optics, working on LCC w/ Pantaleo
• Gal (ABT): Tracking studies on MIK injection scheme

Top-Up Injection Status gitlab link

• Repository updates 
  • Loss locations (S7): Discrepancies between SAD and Xsuite, Takashi will update the loss output to show meters instead of element ID
  • Beam matching issues at injection likely linked to beam-beam element.
    • S8 simulations without beam-beam still show injection inefficiency.
  • Simulation comparison:
    • with beam-beam SAD: ~80% efficiency. Xsuite: ~66% efficiency.
    • Large discrepancy on beam-beam impact 
      • much larger than results showed at FCCweek 
    • Potential source:
      • mismatch in injected beam parameters.
      • injected beam in Xsuite uses the SAD distribution
      • Giulia and Kyriacos + several others working on a tool set that will ensure setup and reproducibility of results
      • Marc-Andre recommends to check the beam-beam force effect on the lattice w/o SR and using FFT on the tracking

Nonlinear Kickers and Injection Schemes

• Review presented at low emittance workshop 2024 here by P. Alexandre (ESRF)
• Present work in ABT aim at establishing specifications for a MIK
• for FCC
  • Initial work by P. Hunchak, for instance here
  • no bump of circulating beam

• Marc-André matching universal straight from GHC section to LCC. -> LCC will be available soon as drop-in replacement for the purpose of injection tracking
