  • Kickoff Meeting 07-09.04.09
  • Awaiting authorisation from CERN Management for increased cost


  • Status of negotiation with manufacturer (FrankGerigk)
    • production problems (cracks in surface) increase production cost
    • find new subcontractor for small cylinders to make them twice as long and cut later at CERN in order to reduce the cost


  • Status of the circuit model (FrancescoGrespan)
    • good agreement found for a simple model with 2 drift tubes and one post coupler
    • reduce model to 1 drift tube with 2 half post couplers
  • Hot Protoype (SuitbertRamberger)
    • vacuum tests not yet completed
    • test stand in SM18 not available following delays on vacuum tests
    • first high power tests at 3MeV test stand early March
    • install radiation shilding if neccessary. Contact Carlo Rossi
  • Power coupler simulations (GiovanniDeMichele)
    • HFSS, MWS simuations
    • determine scaling factor with simplified geometry


  • allocation of construction and storage space for all structures has to be done far in advance. Contact JeanMichelGiguet

New Meeting Time: Fridays 14.00-15.30
