Minutes RF structure meeting 13.02.2009

F.Gerigk, S. Ramberger, G. DeMichele, F. Grespan


  • Awaiting authorisation from CERN Management for increased cost



  • Drift Tubes Design (SuitbertRamberger)
    • Thierry test the e-beam welding between end-cup and core with magnet inside, observing before without shielding then with aluminum shield
    • There are different configurations of permanent magnet quadrupoles: the full wedge Halbach design and 'sub-wedge' designs. A full wedge design has considerably lower stray fields.
  • Power coupler simulations (GiovanniDeMichele)
    • found agreement of 3D simulation rescaled to Prototype measurements (HFSS, MWS)
    • start simulation power coupler for Tank 1
  • Status of the circuit model (FrancescoGrespan)
    • good fit of the prototype frequency measurements with the circuit matrix results, taking into account of the next nearest coupling for the Posts
    • to do: simplified 3D simulation for geometrical parameter estimation
