  1. LUSI UPDATE – June, 2008

  2. Project description (1) • LUSI will deliver: • Three X-ray scattering instruments that have been funded by DOE-BES as a “Major Item of Equipment (MIE)” project: • XPP X-ray Pump Probe (Early science - 2010) • CXI Coherent X-ray Imaging (2011) • XCS X-ray Correlation Spectroscopy (2012) • Note: Priority change from previous FAC for XPP & CXI • These instruments will be built at SLAC using SLAC technical staff

  3. Project description (2) Near Experimental Hall Far Experimental Hall 1 3 2 5 4 6 XPP XCS CXI Beam Transport Offset Monochromator Exp. Chamber Detector LCLS LUSI HEDS (NNSA)

  4. Project description (3) CXI WBS 1.3 X-ray transport tunnel XCS WBS 1.4 XPP WBS 1.2 HEDS (outside Funding) SXR imaging XCS Offset Monochromator WBS 1.5 LCLS AMO

Stephenson, ANL (leader) K. Ludwig, Boston University G. Grübel, DESY CXI J. Hajdu, Photon Science-SLAC, Uppsala University (leader) H. Chapman, LLNL J. Miao, UCLA Team Leaders

  8. LUSI Scope • There are six level 2 WBS elements in WBS 1.0 • WBS 1.1 – Project Management • WBS 1.2 – X-ray Pump Probe (XPP) • WBS 1.3 – Coherent X-ray Imaging (CXI) • WBS 1.4 – X-ray Correlation Spectroscopy (XCS) • WBS 1.5 – Diagnostics and Common Optics • Includes XPP, CXI and XCS diagnostics and optics • WBS 1.6 – Controls and Data Acquisition • Includes XPP, CXI and XCS controls and DAQ

  9. Diffractometer & Wide Angle Detector Mover for orienting samples and moving the 2D detector 2D X-ray Detector for collecting x-ray scatter at 120 Hz Shared Laser System including multipass amplifier and pump, optics for beam transport, diagnostics and safety system. Beam diagnostics, x-ray optics, controls and data acquisition Components removed from XPP CD-1 scope X-ray Emission Spectrometer & Small Angle Detector (See responses to the last FAC) All sample environments – strictly budgetary - Would like FAC guidance on what is a good initial suite of sample environments such as a modified “orange” cryostat Ti:Sapphire Oscillator & Regen (Share with AMO) Scope changes are reversible if funding becomes available at a later date XPP Scope

  10. Reduced Scientific Capability since CD-1 Emission Spectroscopy Small Angle Scattering Limited to Room Temperature and Room Pressure Experiments Eliminating Beam Splitting/Sharing Decreases Beam Time Sharing AMO Laser Only allows setting up one experiment at a time Reversible scope changes preserving early science capabilities XPP Science Capability Changessince CD-1

  11. 0.1 to 1 Micron Focus KB Mirrors: KB pairs taking the full direct beam used to produce a 0.1 micron and a 1 micron focus at the interaction plane. Room Temperature Sample Vacuum Chamber to accommodate multiple types of samples and experimental geometries. Particle Injector - with a differentially pumped nozzle - to produce a focused beam of submicron particles delivered from an aerosol at atmospheric pressure to the high vacuum of the chamber. X-ray Detector to measure the diffraction pattern from the sample which will have a central hole to let the direct beam pass. The detector will be read out after every LCLS pulse, at 120 Hz. Reference Laser CXI Major Scope Items

  12. Components removed from CXI CD-1 scope Be Lens - Budgetary Electron TOF – Budgetary Pulse compressor – Budgetary Cryo-goniometer system - Budgetary CXI Major Scope Items

  13. Instrument Functionality compared to CD-1 Limited to small samples, no focus larger then 1 micron Limited information on the explosion dynamics with no electron TOF No ability to shorten the pulse duration to limit radiation damage Loss of capability to transfer unique biological samples to vacuum without cryo system Addition of reference laser Allows off-shift alignment Increases useable beam time Reversible scope changes preserving early science capabilities CXI Science Capability Changessince CD-1

  14. Offset Monochromator for narrowing FEL spectrum, beam multiplexing capability and control of the longitudinal coherence length. Diffractometer for orienting samples, including a local alignment detector Wide Angle Detector Mover 2D X-ray Detector for collecting x-ray scatter at 120 Hz Components removed from the XCS scope since CD-1 SAXS Detector Stage – Budgetary Scope changes are reversible if funding becomes available at a later date XCS Scope

  15. Diagnostics Components removed from scope since CD-1 Wavefront sensor removed – Less expensive alternative will be used initially EO system removed from LUSI scope, but added to potential Accelerator Improvement Projects List WBS 1.5 was expanded to include common optics X-ray Focusing Lens Slit System Attenuators Pulse Picker Harmonic Rejection Mirrors for XPP & XCS Diagnostics and Common Optics Scope Differences since CD-1

  16. Large Offset Monochromator for XPP Sample environment equipment CXI electron time-of-flight CXI pulse compressor CXI cryo-goniometer system Be lens CXI desorption-ionization laser XCS SAXS XPP SAXS Possible Scope Additions (If Contingency Allows) Possible Scope Deletions (If needed) Installation of CXI 0.1 micron K-B and Chamber

  17. LUSI PLANNED FUNDING PROFILE Notes: 1 – Assumes FY08 Reduction of $4M Restored in FY11 2 – Planning for a 6 Month CR in FY09 ($1.5M Q1, Q2) 3 – Loss of $4M in FY08 delays CXI and XCS

  18. BA Plan & BCWS to Fit BA Profile

  19. Cost Estimate Note: Recent scope additions are not included here

  20. Milestone Timeline CD-2 Review is scheduled for August, 2008 and will baseline the entire LUSI project

  21. Features of this Plan • XPP ready for early science in July, 2010 • CXI ready for early science in July, 2011 • Project is BA limited in early FY09 • If LUSI were not BA limited, CXI could be ready for beam 6 months earlier • XCS is ready March, 2012 • Actuals plus commitments through the end of May $2.7M • Contingency is over 35% on estimated remaining work
