4. John Arthur PIXEL Project statusjarthur@slac.stanford.edu April 7, 2005 PIXEL possible funding profile Asking for a total of $50-60M extending over FY06-FY12. About $18-22M would arrive in FY06-08. The funding profile is still being worked out with BES; nothing is certain yet.

5. John Arthur PIXEL Project statusjarthur@slac.stanford.edu April 7, 2005 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. John Arthur PIXEL Project statusjarthur@slac.stanford.edu April 7, 2005 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. John Arthur PIXEL Project statusjarthur@slac.stanford.edu April 7, 2005 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)

8. John Arthur PIXEL Project statusjarthur@slac.stanford.edu April 7, 2005 DOE BES project requirements PIXEL will be a major item of equipment (MIE) procurement project 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 Assume all new rules for BES project management apply

10. John Arthur PIXEL Project statusjarthur@slac.stanford.edu April 7, 2005 Why a phased approach is needed Each instrument costs $12M-$15M Funding profile provides ~$22M maximum by end of FY08 So at most two instruments can be funded through FY08

11. John Arthur PIXEL Project statusjarthur@slac.stanford.edu April 7, 2005 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 2d detector Typical PIXEL “instrument” + PEOPLE

12. John Arthur PIXEL Project statusjarthur@slac.stanford.edu April 7, 2005 The phased approach Build two instruments in Phase 1, plus a prototype 2d detector Have Phase 1 instruments able to use first light (summer 2008) Start to roll Phase 1 science resources onto LCLS ops in 2009 End Phase 1 in 2009-2010 time frame Begin Phase 2 in 2009, hire additional scientists Phase 2 includes two instruments plus additional detectors Finish Phase 2 in 2012

17. John Arthur PIXEL Project statusjarthur@slac.stanford.edu April 7, 2005 Summary The funding profile constraints on the PIXEL project, along with the LCLS schedule, 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
