Minutes RF structure meeting 20.02.2009

F.Gerigk, M. Schuh, G. DeMichele, F. Grespan


  • green light from CERN management to go ahead with the ISTC contract,
  • material order can now go ahead (FrankGerigk)


  • Status of the circuit model (FrancescoGrespan)
    • latest results fit well with measurements at the prototype
    • at model with 4 small cells high second next neighbor influence was detected
    • estimation of capacitance in the same order of magnitude
    • run additional simulation to estimate capacitance as function of the post length
    • run additional simulation to estimate inductance as function of the distance of the post
    • try to fit calibration curves out of the simulation results
  • Power coupler simulations (GiovanniDeMichele)
    • first results
    • resonance frequency decreases with coupler, take into account during tank design (increase frequency).


  • Londitundinal beam dynamic (MarcelSchuh)
    • fast routine using linear fit of ET0 to do longitundinal beam dynamic simulation ready
    • error increases in comparison to exact field integration method at transition has to be checked
    • HOM loading in cavities and feedback to the beam implemented
  • HFSS simulations (MarcelSchuh)
    • simulate new beta = 1 geometry
    • geometry has to be adopted to get a flat top field in HFSS
