The ‘S’ R&D Task Forces
S0High-Gradient Cavities
S1High-Gradient Cryomodule
S2Test Linac
S3Damping Ring
S4Beam Delivery
S5…Sn
To address priority R&D items, RDB has convened several ‘task forces’.
S0-S3 will report on Friday AM GDE plenary
6-Nov-06 FALC Resource Board Global Design Effort 16
The ‘S’ R&D Task Forces
• Addresses current ‘poor’ yield for EP cavities
• Primary goal: establish parameters for routinely producing 35 MV/m EP’d cavities– required 80% yield

Design Changes Under Consideration
RDR MB CCB
214mr IRs supported central injectors supported Removal of service tunnel rejected
conventional e+ source rejected
RF unit modifications (24 26 cav/klys) supported submitted
reduced RF in DR (6 9mm z) supported in prep
DR race-track lattice (CFS) supported in prep
reduced static cryo overhead supported in prep
removal linac RF overhead supported in prep
single-stage bunch compressor rejected
e- source: common pre-accelerator supported in prep

Potential Physics Scope Cuts
• Nobody want's to do this but it may still be necessary– We must wait and see our new "Bottom Line"
• If we are still too expensive, then need to consider 'physics reach‘:– Energy reach: re-defining 500 GeV– Peak Luminosity
• Single IR (push-pull)– not directly a physics scope issue
• These will need to be fully discussed and coordinated with the Physics Community– Physics Parameter Group– MDI panel– (WWS)

What Happens after Beijing?
• Public Release of Draft RDR and Preliminary Costing at Beijing– Cost Reviews, etc– Finalize RDR by Summer 2007?
• Enter into Engineering Design Phase– Planning underway internally– Design will evolve through value engineering
and R&D program– General Goal is to have Construction Proposal
ready by 2010

Summary• Status of Costing
– First costing available at Vancouver (July)– Cost to performance optimization
• Component level cost reduction (requirements) • Machine design changes• Changes effecting physics performance
• Status & Plans for design modifications– Several proposals accepted and some rejected– Changes having physics impact (Valencia)– Complete RDR by Beijing Meetings
• Global planning for critical R&D beginning– Formation of ‘S’ task forces
