Introduction: Technical Guideline for TDR-SCRF

• Akira Yamamoto (KEK)

Room: Meeting Room A415 - PM's reports by (AY and MR) for - meeting objective - Technical guideline with current view for the TDR baseline design and the cost study

Cavity Gradient

• Rongli Geng (Jefferson Lab)

Room: Meeting Room A415 - Scope for improving the gradient, - Production Yield and the variation assumed, - Degradation after the cavity string assembly - Scope for 1 TeV

Cavity Integration

• Hitoshi Hayano (KEK)

Room: Meeting Room A415 - Plug-compatible envelope - Tuner, Input-coupler, beam-flange, magnetic shield, etc. - LHe tank, suspension scheme and alignment, etc.

Cryomodule

• Paolo Pierini (INFN Milano LASA)

Room: Meeting Room A415 - Cryomodule envelop and interface (flanges etc..) with plug-compatility - Simplification of 5 K radiation shield - Assembly, alignment, tolerance, and deliverable conditions - Cryomodule unit: desired to be (8+4Q4+8) - Conduction cooled, splittable SC quadrupole - High-pressure-code issues - Interface to CFS

Cryogenics

• Tom Peterson (FNAL)

Room: Meeting Room A415 - Thermal balance with cryomodule thermal load, - Cryogenics unit and locations: hopefully to be reduced (5 to 4 units / linac) - Interfaces to CFS

HLRF

• Shigeki Fukuda (KEK)
• Christopher Nantista (SLAC)

Room: Meeting Room A415 - Baseline design and backup solutions for KCS and DRFS, and RDR backup for each case - Consistent baseline design in ML and BDS (booster) - Power balance and mechanical installation Interfaces to CFS - Specially because of gradient spreads, degradation after installation into cryomodule, and their influence (difference) to the cost,

ML Integration

• Chris Adolphsen (SLAC)

Room: Meeting Room A415 - Beam dynamics, alignment tolerances, possible tilting allowance etc... - Interfaces to CFS: additional tunnel length, - backup length (~400 m?), and - additional length for compensating the degradation. - additional length for CM unit change to 8 +4Q4+8, - 1 TeV extension (assumption and consideration)
