1. The status of RF components G. Riddone, M. Filippova RF development meeting on 24.02.2010

2. The aim of the meeting: to clarify priorities and milestones of supplying the RF components. Projects: TBTS, TBL, KEK, SLAC, Stand-alone test stand, PSI, Trieste/Elettra RF components: Loads Phase shifters Attenuators Hybrids Splitters Directional couplers WR 90 (E/H) bends RF flanges (SLAC design) RF flanges (CERN design) The status of RF components

10. The status of RF components

12. Loads - 10 from CINEL (in 2 month, in the worst case by the end of April 2010) – we asked to double the production rate - two machines will run in parallel Directional couplers - 5 from COBHAM (delivery time of the prototype - June 2010, series - 11 Sep 2010) - 1 from NIHON KOSHUHA (delivery time - 5 July 2010) - 16 from ? (we have asked the price enquiry) - production line also started with China, IHEP Flanges - 100 male from SLAC - 100 female from SLAC We have just received them

13. Conclusions New components will have to be ordered: Loads RF flanges WGs WR90 H/E bends Dates when the components will be needed have to be confirmed
