  23. Long Lead Procurements, FY2005 - Injector • The LCLS Injector • Laser and Laser Room • Main Mechanical Systems • Early integration with SLAC Linac • Laser Systems Assembly in FY2005 John N. Galayda, SLAC

  24. Long-Lead Procurements, FY2005 - Linac • Selected Linac Systems • Superconducting Wiggler • X-band RF system • Chicane Magnets John N. Galayda, SLAC

  25. Long-Lead Procurements, FY2005 - Undulator Systems • Undulator Hardware • Magnet Blocks • Magnet Poles • Strongback • Undulator Measurement System • Final “shimming” of magnets at SLAC • Complete Delivery of Undulators by June 2007 John N. Galayda, SLAC

  26. FY2005 Long Lead Procurements ($K, as spent) 28% Contingency (67% contingency on Superconducting wiggler & spare) To be reimbursed to TEC when Special Spares Funds are allocated. John N. Galayda, SLAC

  27. Long Lead Procurement Rationale- Mitigation of Schedule Risk • Injector • Must run smoothly for FEL commissioning • Develop repertoire of current pulse options for FEL commissioning • Undulator • Two-year delivery schedule • Support early start of FEL commissioning • Undulator Measurement Lab • Develop SLAC expertise in time to accept production undulators John N. Galayda, SLAC

  28. Long Lead Procurement Rationale- Mitigation of Schedule Risk • X-band Structure/Klystron/Modulator/LLRF • NLC collaboration is best source- no large spares inventory on site • Early test of SLAC modulator/x-band klystron combination • Early achievement of necessary phase stability • Chicane Magnets • Bunch Compressor 1 (BC1) identical to Injector Dogleg 1 (DL1) • BC2 design easy to accommodate with FY2005 PED funds • Superconducting Wiggler • Minimize in-house design workload • Allow ample time to accommodate slippage in delivery schedule John N. Galayda, SLAC

  29. Long Lead Procurements – Technical Risk Assessment • Injector Linac hardware is well within state of the art • Existing SLAC hardware designs meet most needs • Undulator Prototype meets LCLS specification • Design permits assembly by non-experts • Undulator Measurement System – proven at APS • Superconducting Wiggler well within state of the art • Several similar devices worldwide • X-band power, gradient requirements much less stringent than NLC requirement John N. Galayda, SLAC

  30. Long-Lead Procurements – Cost Risk Assessment • CD-3A for Long-lead procurements follows CD-2 for project • Overall project budget baseline will be reviewed/accepted before long-lead procurements are authorized • Addition of magnet measurement facility to scope • Offset by expected savings in undulator procurement • Increased estimate(contingency) for superconducting wiggler • That’s life • Reimbursement from Special Process Spares account 2007 John N. Galayda, SLAC

  31. Long-Lead Procurements • Cost and Technical Risks are low • Important to the Early Start of Commissioning • Important to the Timely Completion of the Project John N. Galayda, SLAC

  32. Sub-Picosecond Pulse Source • Chicane Commissioned Winter 2002 • Bunch compression studies • Bunch Length Measurement • Wake field investigation • Test of short-bunch diagnostics • Control of pulse timing • First Light on Monochromator 16 May 2003 • X-ray experiments • X-ray pulse length measurement • Timing control of linac pulse with respect to pump laser • Focused SPPS beam may be used for damage studies, validation of coded John N. Galayda, SLAC
