  1. LCLS Photon Systems Installation and Commissioning Hal Tompkins LCLS Photon Systems Deputy Manager Presentation to Facility Advisory Committee October 29, 2007

  2. Important Dates • Beam Dump Co-occupancy - 12/5/07 • FEE and NEH Co-occupancy - 12/21/07 • FEE and NEH Beneficial Occupancy - 3/21/08 (NEH elevator - 4/08?) • X-Ray Transport Tunnel Co-occupancy - 1/08/08 • FEH Co-occupancy - 3/24/08 • Tunnel/FEH Beneficial Occupancy - 6/23/08

  5. Beam Dump Installation • Electron beam dump installations are critical. • Must install two electron-photon stopper systems, fast shutter, collimator, penetration tube, and backfill steel and concrete in Muon Wall 1. • Expect to certify PPS though electron beam dump in 10/09. • This allows electrons into BTH, UH, etc.

  6. FEE Installation • Fixed Mask, Adjustable Slits, Gas Detectors, and Gas Attenuator make up phase 1 (June 11-July 1, 2008). • Calorimeter, K-spectrometer, Soft X-ray imager, and Direct imager make up phase 2 (July 2-23, 2008). • Soft x-ray Offset Mirror System (SOMS) is phase 3 (Jan. 16-Feb. 5, 2009). • Note the gap between phase 2 and phase 3. This is driven by deferring purchase of the FEE Mech/Vac (mainly collimators) and pop-in monitors to FY09 for budgetary reasons. It is not driven by delivery date of SOMS mirror substrates. • Hard x-ray Offset Mirror System (HOMS) is phase 4. This is close to being delivery-date dependent (Feb. 6-26, 2009). • PPS/BCS installed by 2/09.

  7. NEH Installation • Vacuum transport through hutches 1 and 2 will be installed. • Anticipate LUSI will handle vacuum transport in hutch 3. • XES laser installation begins with NEH B.O. and is expected to be complete in 5/09. Commissioning the laser diagnostics and controls follows immediately afterwards. • AMO experiment installation begins with NEH B.O. and is slated to be complete in 7/09.

  8. Tunnel/FEH Installation • X-Ray Tunnel and Far Experimental Hall component purchases also delayed until FY09. • FEH hutch construction estimated at 8-9 months.

  9. FEL Commissioning Timeline

  10. Commissioning • Nominal first beam to FEE is 5/14/09 • Commission the X-ray diagnostics simultaneously with commissioning the undulator. • Start with Direct Imager, then move on to Adjustable Slits, Gas Detectors, the Attenuators, and the Calorimeter. • Then do K-spectrometer and Soft X-ray Imager. • Align and characterize the spontaneous radiation beam • Measure photon flux per pulse • Find SASE and optimize gain (first at low energy) • Deliver beam through offset mirror systems to experiments in NEH hutches.

  11. Commissioning • Stabilize FEL for User Run • User Run • SLAC shutdown • Recommission upstream pieces of LCLS • If ready, transport x-rays into Tunnel and Far Hall • Detect x-rays in Far Hall - complete CD 4 • Continue working on lasing at higher energies • Alternate machine work with experiments

  12. Summary • Very tight schedule between first beam to FEE and User Run - driven by FY08 budget limitations. • Very tight schedule between AMO experiment installation and User Run - driven by FY08 budget limitations. • We think we have a good shot at lasing at 1.5 nm for the User Run - stability is a bigger question. • Operation at .15 nm for the User Run will likely be with spontaneous radiation.
