EP facilities for ILC R&D
EP beds/HPR/CR….= KEK properties.Building = Nomura properties.Operated by Nomura personnel.
Location is Kanuma: 70 km away from KEK. It takes 2 hours for transportation from Nomura to KEK.
Superconducting Test Facility (STF)Building/EP beds/HPR/CR …. = KEK properties.Operated by KEK personnel.

• Post-EP Rinse process is very important to eliminate FE. Now ethanol(DESY) and degreaser(Jlab) rinses are in the standard recipe in these Lab’s. KEK is interested in H2O2 rinse. Post-EP Rinse setup will be installed.
• Pre-EP removes dirty particles after tumbling. Fresh-EP has similar effect to post-EP rinse. Both processes cannot use EP acid in tank. We need additional fresh and waste acid tanks.
• After VT, cavity is disassembled and the indium sealing of flange should be removed completely by Chemical-Polish (CP) for next assembly. Flange-CP setup will be installed for this.
• Robot arm will be installed around EP-bed. One operator can handle 9-cell cavity + jigs easily by this robot arm.
• Cavity-CP (BCP) is necessary, even if it is not essential for KEK standard recipe. Full-automatic cavity-CP (BCP) system cannot be installed due to the lack of budget. Man-operated cavity-CP (BCP) setup is planned to be installed.

Large walk-in type draft-chamber will be used. Man-operated (non-automatic) CP setup is planned, simply due to the lack of budget. CP acid and waste tanks + pump are needed. Still discussing the design.

• Two EP beds cannot be used in parallel due to safety reason, but during one EP bed is used for EP, the other can be used for the next EP setup. This will raise the efficiency.
• We are assuming the capacity of STF/KEK EP facility = twice EP processes per week utilizing two EP beds.
• The schedule of EP processes for STF2 cavities depends on the fabrication schedule of cavities. We roughly estimate that the EP processes for STF2 cavities might start from the beginning of 2010.
• Rough estimation of STF2 EP schedule: 28 cavities for 2 years and 4 months (28 months), assuming 1 cavity with 3 EP’s and 2 VT’s, utilizing Kyoto-camera checks. This occupies only 38% (3/8) of the capacity of STF/KEK EP facility.
• The rest of the EP capacity at STF/KEK can be used for S0 and fundamental R&D activities for ILC, and other project: KEKB and ERL.
EP schedule for STF2 production and S0
Summary• EP facilities for ILC R&D at KEK are currently located at STF/KEK and
Nomura Plating Co.• EP bed, Ultrasonic cleaning, HPR have been already installed at
STF/KEK.• Alcohol/degreaser/H2O2 rinse, Pre-EP, Fresh-EP, flange-CP, Robot-
arm, cavity-CP facilities will be installed within 3 months.• EP facility will start regular EP processing from January 2009. • EP facilities at Nomura will be moved to STF building at KEK in the
middle of Year 2009. Then Nomura EP facility will be terminated.• The EP process of 9-cell cavity can be performed twice per week
regularly utilizing two EP beds at STF/KEK. This capacity is enough for STF2 production, S0, and fundamental R&D activities for ILC.
