RFCC Schedule and Manpowerand Review Wrap Up
RFCC Module Preliminary Design Review June 4,
2008

• Steve Virostek
• Lawrence Berkeley National Lab

2
Schedule Overview

• RFCC design and fabrication project originally
  expected to be a 3year project (10/06 to 10/09)
• Coupling coil effort began in 2006 at ICST
  (Harbin)
• Design and fabrication of other RFCC module
  components was scheduled to begin 10/07
• Start was delayed due to lack of availability of
  qualified manpower
• Earlier this year, mechanical engineer A. DeMello
  joined MICE to work on RFCC module design (FTE)
• Additional manpower required to make up schedule

Wrap Up Review Charge

• Evaluate the preliminary engineering design of
  RFCC module
• MICE 201-MHz RF cavity
• Are we ready for purchasing long-lead cavity
  materials and components?
• Copper sheets for cavity body
• Curved and thin Be windows
• Ceramic RF windows
• Evaluate engineering design of the 201-MHz cavity
  and fabrication scheme
• Spinning of cavity shells
• E-beam welding
• Port extruding
• Cavity support and tuners
• Overall module concept
• Confirmation of interface with other modules and
  site
• Integration and shipping
• Detailed design of coupling coil is not part of
  this review

Wrap Up Review Summary

• MICE cavity design is heavily based on successful
  MuCool 201-MHz prototype RF cavity and lessons
  learned
• Fabrication and post processing
• Cavity conditioning and operation
• Engineering design of the cavity is essentially
  complete
• CAD model of the cavity, tuners, support and
  vacuum
• Fabrication schemes
• Significant progress on RFCC module engineering
  design
• Possible operation at LN temperature?
• Current design accommodates LN operation, but it
  looks very challenging
