  1. e-Beams Systems Update David Schultz • People • Issues from the last review • LTU and Dump Installation Status • Undulator System Status • Controls Status • Installation Readiness Reviews • Accelerator Readiness Review • Schedule and Budget • Linac and Undulator Risks

  2. E-Beams System CAMs • Jose Chan is the Control Account Manager for LCLS Linac and Undulator Systems at SLAC. WBS 1.3, 2.3, 1.4.6 • Geoff Pile is the Control Account Manager for Undulator Systems at ANL. WBS 1.4, 2.4

  3. New responsibilities • Jim Krebs has joined LCLS as Deputy e-Beam Systems Manager. • Enzo Carrone has joined LCLS and the Controls Department as the Deputy Controls Head for LCLS.

  4. E-Beams systems since the last review (1) • Injector and Linac/BC2 commissioning is complete. • The ‘07 downtime installation went very well. • These systems, through linac sector 30, have been handed over to operations. • The Undulator vacuum chamber crisis is behind us. • The extruded Al chamber was adopted when internal polishing was demonstrated as acceptable. The extruded Al chamber meets all specs. • All chambers and supports have been fabricated and are at SLAC.

  5. E-Beams systems since the last review (2) • Undulator tuning at the MMF here at SLAC is going well. • All Undulators have been received from ANL • Problems: • Storage temperature, 15 need refiducialization • Undulator aperture, 7 need rework, at SLAC • 1 low-strength magnet block • 26 Magnets tuned / 6 with feet RFI (as of 4/29) • Interference found between Undulator shims and Vacuum chamber being addressed – ref. Zack Wolf’s talk

  6. LTU stand installation 4/21/08

  7. LTU and Dump status • LTU installation is underway. • Support stand and cable plant installation has begun • Magnet installation in the BTH-West begins 5/20. • Components are RFI with few exceptions • Vacuum chambers are arriving from the vendor • Dump vacuum assembly is nearing completion • Spot shielding is in fabrication. • Contracts are with purchasing for dump steel and dump component installation.

  8. Undulator girder assembled at SLAC 4/15/08

  9. Undulator status • Undulator magnets are here, in tuning for modification • Most of ANL deliveries are complete, or soon will be. • Quads, Vac chambers and supports, Girders and supports, bellows, ion pumps, … • Quad measurement underway at SLAC • 7 RFI (5/5), all RFI by 6/30 • Controls racks due 6/15, RFI • Girder assembly is underway • 1 complete, 5 partial • Installation of supports waits for tunnel occupancy

  10. Undulator status • RF Beam Position Monitor • Have had productions problems with developing the process attaching the vacuum windows onto the body. • Now have a process which works. Developed and done at ANL (not at vendor). • 5 BPMs RFI at SLAC, all BPMs at SLAC 7/31

  11. Undulator status • Beam Finder Wire • Have had problems with wire position reproducibility. • Solution is in hand, production at ANL is steady. • 3 BFWs RFI at SLAC, all BFWs at SLAC 6/10.

  12. Undulator girder assembly schedule Near the Project critical path = RFI We are ahead of this schedule. ANL component delivery is now sufficient to support assembly.

  13. B913 & B921 PS racks B911 & B912 PS racks Controls Power Supply Racks Loaded and Tested

  14. Controls status • Cable plant installation for the LTU, Undulator and Dump is underway, the schedule is tight. • Power supply racks are RFI. I&C racks are arriving late, crates, IOCs, in hand. • Should still be possible to load and test the racks in the lab. • Undulator controls racks arrive 6/15 from ANL • Software is being checked out at ANL. • First articles will be tested at SLAC prior to installation • Safety and protection systems (PPS, MPS) are on track.

  15. Installation Readiness Reviews • Installation Readiness Reviews were held • 2/26/08 for the LTU and Dump. • 4/17/08 for the Undulator. • Recommendations: • Appoint an oversight person for Undulator integration. • Jim Krebs has been appointed • Review cable plant  girder installation conflicts. • Installation sequence has been altered to minimize impact, some delay to girder installation.

  16. Work Planning and Control • LCLS & SLAC work planning and safety approval processes are followed, which incorporate ISEMS hazard controls. • The mechanical and cable installations are by contractors. • LCLS Installation managers and SLAC UTRs handle oversight during the work. • Technical installation is done by SLAC technicians. • Trained and supervised by their home departments. • All work reviewed daily at the 07:00 tailgate meeting held by the LCLS Installation managers. • Turner and LCLS meet weekly for co-occupancy schedule integration.

  17. LCLS Accelerator Readiness Review • Safety Assessment Document • The existing LCLS SAD and ASE (Injector and Linac) will be updated to include the LTU through the NEH. • Writing has started, due date is July • The SAD will need revision in 2009 for the x-ray tunnel and FEH. • Accelerator Readiness Review (ARR) • The ARR will be held this November for commissioning to the electron beam dump. • Bob Casey of BNL to Chair • Readiness Reviews for the FEE, NEH and FEH hutches will be done later.

  22. Linac and Undulator Risks • R-1.3-007 Emittance measurement upstream of BC2 • Emittance measurements with Sector 28 and LTU wire scanners might not provide adequate understanding for Undulator commissioning • Measuring beam with Sector 28 wire scanners now to better understand this risk. • R-1.3-008 Linac stripline BPM sensitivity • Old BPM electronics are slow and yield poorer resolution than the new models, and may be insufficient. • New electronics installed in critical locations show much improved performance, resolution and speed.

  23. Linac and Undulator Risks • R-1.4-026 RF BPM Schedule • Delayed production of the RFBPMs could delay girder assembly. • Production is now on track, and an assembly work-around was developed. • R-1.4-027 Undulator Component Deliveries • Problems with assembly of Undulator hardware could lead to delays. • Improved communication (weekly tech meetings, Undulator weeks (3)) has greatly diminished this concern.

  24. Summary • Installation has begun in the LTU. • Installation in the Undulator and Dump has started. Late: area co-occupancy and D-B contract release. • Component availability will not be a limiting factor. • Undulator components are at SLAC awaiting installation. • Parts are arriving now in sufficient quantity to support girder assembly. • Girder assembly is near the Project critical path, and ahead of that schedule. • Controls installation is underway, but Controls checkout is last, as always.
