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
