  1. FEH Layout, Status John Arthur – LCLS Expt’l Facilities Div June 3, 2009

  2. LCLS new construction Undulator Hall Near Experimental Hall Front End Enclosure Far Experimental Hall

  3. First LCLS FEL light at 1.5 Å

  4. Gain vs undulator length at 1.5 Å FEL gain length = 3.3 m FEL saturation indicated Pulse energy ~ 1 mJ

  5. The LCLS X-ray Beamline 3 Hutches X-ray transport tunnel Far Experimental Hall 3 Hutches Near Experimental Hall Front End Enclosure

  6. FEE Solid Attenuators Gas Attenuator Calorimeter Beam Direction Slit Gas Detectors K-Mono 5 mm collimator Direct Imager (Scintillator) FEL Offset Mirror Systems

  7. LCLS Offset Mirror Systems 800-2000 eV to Hutch 1 HOMS: Hard x-ray Offset Mirror System SOMS: Soft x-ray Offset Mirror System insertable 800-2000 eV to Hutch 2 Shadow Wall Wall 2 insertable 2000-25000 eV to Hutch 3-6

  8. Far Experimental Hall

  9. FEH Hutch Layout HPS control Roll-up door (interlocked) Online-offline status lights HPS door (one per hutch) PPS door (Tunnel entrance) Accelerator status lights (two places) PPS control (keybank, etc) exit

  10. FEH Hutch Layout Detail HPS control Roll-up door (interlocked) Online-offline status lights HPS door (one per hutch) Accelerator status lights (two places) 9 m 20 m

  11. FEH Hutch construction plan • Bids were well below estimates • Contract about to be signed • Steel frame procurement already under way • Construction finished Dec 2009 • CXI installation could start early 2010 • Basic services installed Feb 2010 • Network, PPS

  12. Open issues with hutches • PPS design needs to be finalized • Utilization of mezzanine • Cooling water system upgrade These issues will be easier to resolve when instrument designs are final

  13. Summary • LCLS works • FEH hutches will be ready in early 2010 • Operations support including User support is in place • Support staff being hired
