LCLS

2. Boundary conditions that define the PIXEL project

DOE funding profile
LCLS science thrusts endorsed by SAC

Phased approach
Straw man schedule

3. LCLS Construction Schedule
NEH beneficial occupancy June 2007
FEH beneficial occupancy September 2007
First electrons through undulator December 2008 (maybe June)
Begin LCLS operations phase April 2009

4. PIXEL possible funding profile
$millions
Total = $50M-$60M

5. The LCLS Science Thrust Areas
Coherent scattering at the nanoscale (XPCS)
Atomic, Molecular, and Optical Science
Pump/probe diffraction dynamics
Pump/probe high-energy-density (HED) science
Nano-particle and single-molecule (non-periodic) imaging

6. BES approach to the Thrust Areas
AMO science will be included in LCLS construction project
HED science deemed to be outside the mission of BES

7. Proposed PIXEL Scope
Build instruments that address the 3 remaining Thrust Areas within BES mission
Include one additional instrument, for soft-x-ray coherent imaging of magnetic domains (also endorsed by SAC)
Include HED Science if outside (non-BES) funding can be found

8. DOE BES project requirements
Not a line-item in the DOE budget
Can include construction funding and R&D funding
Must build distinct instruments, separate from what LCLS builds
All new rules for BES project management apply
PIXEL will be what is called a “major item of equipment” (MIE)

10. Why a phased approach is needed
Each instrument costs $12M-$15M
Funding profile provides ~$22M maximum by end of FY08
However, $50M-$60M can be expected by ~2012

11. What will $12M-$15M buy? Controls (including laser timing)+Computers
Slits
Flight path
Valves/windows/pumps
KB focusing system (1 µm and sub-µm options)
X-ray pulse split+delay with table
Crystal monochromator with table
Diffractometer with table
Optical table for laser
Laser PPS
Laser system (10 mJ Ti:sapphire plus OPA)
Laser diagnostics
X-ray diagnostics

12. The phased approach
Build two instruments in Phase 1, plus a prototype 2d detector
Have Phase 1 close to completion by first light (summer 2008)
Finish Phase 1 by April 2009 (begin LCLS operations phase)
Roll Phase 1 science resources onto LCLS ops in 2009
Begin Phase 2 in 2009, hire additional scientists
Phase 2 includes two instruments plus additional detectors
Finish Phase 2 in 2012

13. Proposed Project Milestones
CD0 (Statement of mission need, beginning of project) 6-05
CD1 (Completion of conceptual design)
CD2a (Baseline costs of Phase 1)
CD3a (Begin construction of Phase 1)
CD4a (Finish Phase 1)
CD4b (Finish Phase 2)

15. Near Experimental Hall
2008-9
Soft X-ray Station
AMO Physics (funded by LCLS)
Hard X-ray Imaging Station
Coherent imaging (funded by PIXEL)
Extreme states of matter (funding?)
Hard X-ray Diffraction Station
Pump-probe dynamics (funded by PIXEL)
XPCS (funded by PIXEL)
Green applications do not have full capability, but can do preliminary experiments
Far Experimental Hall

16. Near Experimental Hall
by 2012
Soft X-ray Station
AMO Physics
Magnetic imaging
Hard X-ray Imaging Station
Coherent imaging
Hard X-ray Diffraction Station
Pump-probe dynamics
Hard X-ray Diffraction Station
XPCS
Hard X-ray Station
Extreme states of matter
(assumes funding found)
Far Experimental Hall

17. The funding profile constraints on the PIXEL project, along with the LCLS schedule, seem to indicate that a phased approach is needed
Two instruments in Phase1, two in Phase2, along with a detector development program
Funding for this project is lean, especially in the first years
Strong support from the Science Teams will be needed
