  1. Photon Beam Systems Project Activities Geoff Pile – Photon Beam System Construction May 13, 2009

  2. Photon Systems Overview and Status • Scope of Photon Systems • Safety • Current status • Schedule leading to first light in FEE and NEH • Cost and Schedule • Summary

  3. Photon System Responsibilities • XTOD • Transport the x-ray beam, in vacuum, to experimental stations • Condition the x-ray beam, with attenuators and apertures • Analyze the x-ray beam, with sophisticated diagnostics • XES • Provide basic infrastructure required for experimenters • Build instrument for Atomic Physics experiments • Advanced x-ray detector R&D

  4. Photon System Management Team • G. Pile – (LCLS XFD/Strategic Projects) • Photon Systems Installation and Engineering (March 1st - Summer 09) • LCLS Construction Priorities: Installation of equipment in FEE, Hutch 1 (AMO) & Hutch 2 (SXR) • Additional help/resources from Engineering Physics Division and SLAC Mechanical Fabrication Department • J. Arthur – (LCLS XFD) Photon Systems Operation • Create XFD Operations Group • Augment scientific and support staff • Create structure for safe operations • Begin User program • LUSI: Help Accelerate schedule

  5. X-ray Transport, Optics and Diagnostics (XTOD) WBS 1.05, 2.05 LLNL • Head: Richard Bionta, CAM: Donn McMahon • X-ray (XTOD) Installation CAM: Hal Tompkins • X-ray End station Systems (XES) WBS 1.06, 2.06 • Head, CAM: Stefan Moeller • AMO Experiment CAM: Jose Chan • SXR Experiment CAM: Michael Rowen • NEH laser CAM: Bill White Photon Systems Managers

  6. X-ray Controls & Data Acquisition, WBS 1.05.02, 1.06.02 • Gunther Haller: Head, CAM: Don McMahon • X-ray Commissioning, WBS 2.06.03 • Hal Tompkins, CAM • X-ray Mech-Vacuum, NEH, XRT & FEH WBS 1.05.03 • Carl Rago, Lead Engineer More Photon Systems Managers

  7. Safety Minute • Photon Systems now in full installation mode: Safety is highest priority • Dedicated Photon Systems “Tool Box” meetings • Held 7am daily at construction site • Installation coordinator (Rich Atkinson) conducts meeting – presentation style and edited on the fly with appropriate supervisory input • Usually 8 -10 supervisors & coordinators attend • Up-coming work is also discussed, only today’s work is authorized • Installation coordinator publishes work list and minutes to web site at meeting conclusion • Installation CAM (Hal Tompkins) attends daily & provides general oversight and management input • LCLS Project Director (JNG) attends regularly, every week

  8. Commissioning Time-Line First FEL Light • Commissioning • Project Milestones • Installation Periods First Light in FEE 6/11/09 Install Undulators Project complete First Light in FEH First e- to dump First e- from gun PEP-II ends X-Rays in NEH FEE/NEH Install First Light in FEE LTU/Und Sys Install First Users Injecrtor Install BC2 Install J F M A M J J A S O N D J F M A M J J A S O N D J F M A M J J J F M A M J J A S O N D D A D M 2007 2008 2009 2010 Down Down Down Down NEH FEH Linac Injector LTU/Und Linac/BC2 FEL/FEE

  11. Photon System Level 2 Milestones

  12. FEE Construction

  13. FEE Controls in Check-out Phase

  14. The 5 main elements of AMO experiment Pulse Picker Slit System Refocus Optics (LBNL) Optic mirror coating (LLNL) High Field Physics Diagnostics Magnetic Bottle (Ohio State University) Energy Monitor (LLNL) • Schedule for AMO • Complete assemblies in May 2009 • Complete mechanical instrument installations by June 30th • Can start AMO commissioning in July (w/o Refocus System & Magnetic Bottle) • Install Refocus Optics by the end of July • Update all red-lined drawings and release to document control Atomic Molecular Optical Instrument (AMO) Jose Chan Engineering and Cost Accounting John Bozek Instrument Scientist

  15. SXR Instrument • SXR instrument had slow start due to funding issues • Very ambitious schedule but do-able - 3 to 4 weeks float to final installations • Critical paths are : monochromator and the K-B mirrors. • SXR should be ready for beam by the end of February 2010. Photon Stopper K-B FocusOptics Beam Dump Exit slit & Spectrometer Detector End Station M1 Mirror & Grating System Transmission sample Chamber Single pulse shutter

  16. WBS 1.5 and 1.6 Cost and Schedule • 1.5 Pie charts for Completed and Remaining Work • CPR at level 3 • Variance Analysis • 1.6 Pie charts for Completed and Remaining Work • CPR level 1 only • Variance Analysis not required Summary from Cost Performance Reports Reporting Period: March 31, 2009

  17. X-ray Transport Optical Diagnostics WBS 1.5 Completed and Remaining Work Installation 1,572,478 Proc/Fab/Assy 1,970,450 Dsn/Engr 592,013 Admin/Mgmt 153,860

  18. X-ray End station System WBS 1.6 Completed and Remaining Work Installation 1,757,979 Proc/Fab/Assy 3,637,133 Dsn/Engr 2,230,790 Admin/Mgmt 232,407

  19. 1.05 Variance Analysis CPI SPI Budgeted Revised Variance

  20. 1.05 Variances Cont. • Controls Var: 0.79 SPI = $1.14 M • Mechanical Vacuum Subsystem Var: 0.65 CPI = $267K • X-ray Transport and Installation Var: 0.39 CPI & 0.58 SPI = $463K P3 Actual cost of work $33.0M P3 Budget $33.4M P3 Estimate At Complete $37.3M Variance $3.9M • LLNL: remaining work to go = $2.153 • BA for plan + Commitments + Actuals to date = $1.802 + 0.4 = $2.2M • SLAC: remaining work to go = $1.716M • $120k CF miss-charge give back + plan look reasonable • May require additional BCRs for extra Engineering ($250k TEC) and Physics Commissioning ($350k OPC)

  21. Risks & Challenges • Design changes (e.g. changes in radiation shielding requirements) • Continued good communication with Rad Physics, users • Controlling process: Many FDR Reviews in last two months, PRDs, ESDs, ICDs • Recently - Thorough Ray Tracing showed slight design modifications required • New designs already in hand, procurements out for modification • SLAC Vacuum spec: very difficult to meet for some diagnostic parts • Need to work on relaxed LCLS Photon System/User spec. • Rago brought in as authority on “non compliance” acceptance – SLAC Vacuum Group helps collaborators with advice and/or help with additional bake out, RGA scans etc. • Cost and schedule • Collaboration required – SLAC providing resources to help mitigate schedule slip • XTOD vacuum system scope moved from LLNL to SLAC to help schedule • Alternative preliminary design accepted – lower cost, integrates with CXI, XCS, future requirements and has simplified installation • Close to FDR – no show stoppers – excellent schedule – helps with Costs

  22. Photon Systems Six Month Look Ahead • Installation & Commissioning • Mid June 2009, Start FEE Commissioning with Beam • Mid to Late July 2009, First X-Rays into NEH, ready to start Expt'l Ops • Late - JULY 2009, Start AMO Commissioning • Aug 2009, Complete X-ray Tunnel Installation • Sept 2009, XE Start Installation in FEH • Operations • Sept-Dec 2009, with 1 instrument (AMO) • Mar-July 2010, with 2 instruments (AMO, SXR) • Aug-Dec? 2010, with 3 instruments (AMO, SXR, XPP) • 2-3 more instruments in 2011

  23. Summary • All Schedules look very ambitious for early science – but definitely achievable • Up-stream Electron Systems - installed and operate with no compromise • Photon Systems – will be installed the same way • Engineering quality and safety will not be compromised, we have lots of experienced help We’re on target!
