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.

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

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

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)

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

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

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

CD1 (Completion of conceptual design) mid 2006
CD2a (Baseline costs of Phase 1) late 2006
CD3a (Begin construction of Phase 1 mid 2007
CD4a (Finish Phase 1) 2009-2010
CD2b (Baseline Phase 2) 2008-2010

SummaryThe 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
