  3. Five Cavities at KEK for S-1 Global STF-BL #7 Cavity (MHI-07) STF-BL #8 Cavity (MHI-08) STF-BL #9 Cavity (MHI-09) STF-BL #5 Cavity (MHI-05) STF-BL #6 Cavity (MHI-06) Delivery in 2008’ March Delivery in 2009’ March ILC meeting @ KEK Global Design Effort

  4. Surface Preparation at STF EP Hot bath Rinse C2H5OH, Degrease Flange-CP Assembly (Class 10) HPR Infrastructure in the STF Hall System check with AES#1 cavity was carried out in Oct., 2008. Vertical Test Inspection of Inner Surface Pre-tuning fo adjustment Hanging Stand Baking (Class 1000) ILC meeting @ KEK Global Design Effort

  5. Summary of VT at STF (MHI-05 ~ 09) Oct, 2009 Cavities for S1-G 5 Cavities 15 Vert.Tests for 1 year (Dec. 2008’ ~ Nov. 2009’) Oct. 29 Nov. 12 Nov. 26 ILC meeting @ KEK Global Design Effort

  6. Four KEK Cavities for S1-Global Oct, 2009 STF Phase-1 MHI-01,02,03,04 20, 30, 20, 20 MV/m ave. Eacc,max = 22.7 MV/m ave. + 5.7 MV/m S1-Global MHI-05,06,07,09 27, 28, 34, 25 MV/m ave. Eacc,max = 28.4 MV/m ILC meeting @ KEK Global Design Effort

  7. Eacc,max (cell) by Passbands modes Meas. Quench by Field emission MHI-05 3rd MHI-06 6th Quench p mode; Eacc,max = 27.7 MV/m > 30. MV/m p mode; Eacc,max = 27.1 MV/m > 35. MV/m Quench Quench by Field emission MHI-09 1st MHI-07 2nd > 35. MV/m p mode; Eacc,max = 33.6 MV/m ~ 40. MV/m p mode; Eacc,max = 25.0 MV/m Oct, 2009 ILC meeting @ KEK Global Design Effort
