FNAL-ANL Cavity Processing Facility

• ANL/FNAL Facility provides a complete processing
  of cavities
• Electro-polishing, ultrasonic cleaning,
  high-pressure rinse, assembly, etc.
• Facility nearing completion (HPR, ultrasonic,
  fixtures)
• Several single-cell cavities and two 9-cell
  cavity electro-polished so far
• Optimization of processing procedure is in
  progress

DESY Key SRF Collaboration

• Fermilabs collaboration with DESY and Tesla
  Technology Collaboration has helped make
  considerable progress in Cavity and Cryomodule
  RDD and SRF infrastructure development.
• Fermilab SRF Infrastructures are 2nd generation
  of DESY

Indian Laboratories Fermilabs Interest

• Fermilab would like the Indian Institutions to
  participate in Project-X research, design,
  development and construction.
• Fermilab and Indian labs are developing SRF
  infrastructure.
• Joint development allows sharing of resources
  and advance the schedule.
• Indian Institutions would develop the designs,
  prototype, and fabricate different components for
  the Project-X SRF accelerator.
• Spoke resonator cavity and cryomodule parts (with
  IUAC and BARC)
• b 0.8 cavity, tuner, helium vessel, etc. (with
  BARC, RRCAT and VECC) to produce a dressed cavity
  and cryomodule parts
• Cost optimization of cryomodule
• Indian Institutions would develop the design and
  fabricate a VTS Cryostat, HTS Cryostat and CTS
  Feed can and End Can for installation at Fermilab
• Similar setup established at Indian Institutions
  to support the above development and Indian
  accelerator Program.

SLAC RF Power

• RF Distribution
• Four, two-cavity RF distribution systems were
  individually high power tested and then shipped
  to FNAL
• Additional systems will be fabricated using ARRA
  funds
• Coupler
• 12 Couplers from CPI have been inspected and
  processed
• SLAC will manage additional coupler purchase
  through ARRA
• Industrial value engineering

14
Laboratory Industry Collaboration

• In 2005 Fermilab helped created an Industrial
  Forum of North American companies to help promote
  SRF accelerator technology.
