Minutes RF structure meeting 08.04.2009

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

DTL

• Prototype still not leak tight after check with PVC plugs (SuitbertRamberger)
• De-Buncher cavity: further studies on-going (GiovanniDeMichele)
• Power coupler:
  • first simulation results with reduced iris length of 270mm to be checked with second method (GiovanniDeMichele)
  • principal mechanical design of coupler with PIMS dimensions (303mm) available (SuitbertRamberger)
• 2m stainless steel tube solution is under study (SuitbertRamberger)
• Drift tube thermal interlock system is part of L. Arnaudons work package, the proposal will be made that J. Marquez works on this system

All Linac4 cavities

• Automatic conditioning system will be built within our section (rack, hardware, software)

HOM

• Emittance growth simulation results for different HOM setups (MarcelSchuh)
• Further simulations with different HOM freqency spread and dirstibutions at machine line resonances to be done
