  1. LCLS Undulator System Status and Schedule Geoff Pile

  2. Safety Minute Even though you wear your PPE you’re not always as safe as you might think. This guy is wearing his face mask while arc welding. In this case, it’s almost as useful as an ashtray on a motorbike. • Two really important statements – • 1. Never Underestimate the Power of Co-incidence (There could be more safety issues less obvious than the one you are trying to negate) • 2. ISM – Do what you say you do! • Define the scope • Analyze (ALL) hazards • Develop/implement controls • Perform the work within controls • Feedback & improvement

  3. All Argonne girder components are planned to be available at least 1 month before the P3 “Early Start” of Girder Assembly Schedule Considerations

  4. Controls Status and Schedule • Controls -1.4.2 – Work Remaining • Undulator In-tunnel Rack (UIR) • Intra Undulator Cables • Electronic Interface Assembly (EIA)

  5. Ongoing Work Completed 1.4.2 - Controls

  6. Undulator In-tunnel Rack (UIR)

  7. Undulator In-tunnel Rack (UIR)

  8. Electronic Interface Assembly (EIA) ~1800 Intra Undulator Cables(pre-made/pre-tested)

  9. Undulator Magnets and Supports 1.4.3 • Undulators (39 @ SLAC 7/2007) • Support & Motion System - girder, cam movers & fixed supports (37@SLAC 3/2008) • X translation issue • Quads and Correctors (36 @SLAC 4/2008)

  10. Ongoing Work Completed 1.4.3 - Magnets and Supports

  11. All 40 undulators were completed by July 2007

  12. Girder Manufacture at Metalex Critical Engineering and QA Oversight by Argonne Girders Assembled and Packed at Hi-Tech

  13. X Translation Stage, Limit Switches, and Adjustable Switch Actuator

  14. Obtaining X Translation Limits & Stops

  15. Tuning block modification

  16. 1.4.3.5 - Quads and Correctors 37 magnets and 2 sets of spare coils completed 4/08

  17. Vacuum Systems 1.4.4 • 46 Vacuum Chambers produced • Manufacture started September 2007 & ended May 2008 • 33 required • 7 spares • 1 LTT • 5 sacrificed for surface finish measurements • Monumental task, huge effort, successful ending. • Interest has already been expressed in this technology by other projects around the world.

  18. 1.4.4 - Vacuum

  19. Inspection and correction of the LCLS VC end flange perpendicularity Inspection of the total length of the LCLS Vacuum Chamber

  20. Surface Finish Data of 46 Chambers…33 required (7 spare – 5 sacrificed – 1 LTT) Transverse: The transverse rms slope tolerance is 60 mrad Longitudinal: Slope Criteria from H-D Nuhn adjusted for the oval shape Desirable Acceptable Not Desirable Should Avoid

  21. Diagnostic Systems 1.4.5 • BPM – 1.4.5.5 • BFW – 1.4.5.6 • BLM – 1.4.5.8

  22. 1.4.5.5 - Diagnostics - BPM

  23. BPM Testing at Argonne

  24. Beam Position Monitor • Large effort- solved serious production problems • Many brazing issues (differential thermal expansion) • Window QA problems • Multi-step Process now understood 8 now delivered to SLAC -remainder on track Promising World Class Diagnostic

  25. 1.4.5 - Diagnostics – BFW & BLM

  26. Beam Finder Wire • All production problems are resolved at this point, but we were somewhat delayed due to issues with repeatability, chamber coating, and electronic modules. • Two units that should have shipped last week are on the way to SLAC at this time. • Details in Dean Walters’ talk

  27. Beam Loss Monitor • Five production BLMs will be used to protect the undulators by inhibiting beam bunches following an “above-threshold” radiation event. • A joint R&D effort is aimed at enhancing these 5 units to enable LCLS to track each undulator’s accumulated radiation dose. • Undulator protection is the highest priority. The BLM will be integrated into the Machine Protection System (MPS) and requires only limited dynamic range from the detectors. • Dose tracking will enable long-term magnet damage to be characterized, but requires a radiation detector with large dynamic range (order of 106) and sophisticated diagnostics hardware and software. • 30 production BLMs may be built in FY09 if R&D is successful

  28. BLM in Inserted Position(Can be easily made to track out with Undulator) Beam Loss Monitor Interface Module

  29. Long Term Test

  30. Long Term Test

  31. Long Term Test

  32. Status and Schedule • Undulator System Management and Integration • CPR & Costs to go – • Generally in good shape. Some unplanned effort has been required in the last two months to solve problems and meet production schedules. • Most spares costs were moved to OPC. Final spares costs will be recalculated using actuals and any required adjustments will be made. • Green Sheet System • A Web-based, almost real time, method of managing Argonne-APS cross- matrixed effort – (up to 60 staff 18FTE’s/year) • ASK System • A Web-based method of managing deliveries and technical documentation. A dictionary/index style look-up system.

  33. Summary • Almost all deliveries complete by July 2008! • Production BLMs? TBD (2009) • Argonne Construction team rolls off the project in July • Argonne Management team drops to half-time in mid-July, and rolls off the project in September. • FY09 – a small budget is included for installation and commissioning support
