Process for Defining LCLS Instruments 2003 Call for Letters of Intent to build instruments and do science with LCLS 2004 32 LOI’s received July 2004 SAC examines LOI’s, groups them into 5 Science Thrust Areas Fall 2004 SLAC and DOE BESAC discuss how to build instrumentation for Thrust Areas May 10, 2005 PIXE Project status John Arthur jarthur@slac. stanford. edu

LCLS Science Thrust Areas Atomic, Molecular, and Optical (AMO) science High-energy-density (HED) science Diffraction studies of stimulated dynamics Coherent-scattering studies of nanoscale fluctuations Nano-particle and single-molecule (non-periodic) imaging May 10, 2005 PIXE Project status John Arthur jarthur@slac. stanford. edu

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 May 10, 2005 PIXE Project status John Arthur jarthur@slac. stanford. edu

Proposed PIXE Scope Build instruments for hard x-rays that address the 3 remaining Thrust Areas within BES mission Include one additional instrument, to address the soft-x-ray portions of stimulated dynamics and coherent imaging Thrust Areas May 10, 2005 PIXE Project status John Arthur jarthur@slac. stanford. edu

PIXE Instruments Ultrafast x-ray studies of laser-induced transient states of matter Nano-particle and single-biomolecule (non-periodic) imaging Nanoscale equilibrium dynamics in condensed matter Soft x-ray imaging and dynamics May 10, 2005 PIXE Project status John Arthur jarthur@slac. stanford. edu

PIXE Detector Development LCLS experiments need new detector technology Dual development strategy for fast 2 -d detectors Several technologies look promising, no clear leader LCLS will pursue one strategy PIXE will try a different technology Both prototypes should be ready by 2009 May 10, 2005 PIXE Project status John Arthur jarthur@slac. stanford. edu

PIXE Phased Approach First LCLS light may come in mid-2008 Budget will not support building 4 instruments by 2008 Phased approach 2 instruments in phase 1 sufficient functionality by mid-2008 to begin experiments phase 1 instruments can support early work in all four areas complete phase 1 while phase 2 is ramping up remaining instruments in phase 2 begin phase 2 after 2008 complete all work in 2012 May 10, 2005 PIXE Project status John Arthur jarthur@slac. stanford. edu

DOE BES project requirements PIXE will be a major item of equipment (MIE) 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 May 10, 2005 PIXE Project status John Arthur jarthur@slac. stanford. edu

Role of the LCLS Science Teams are responsible for preparing physics requirements for PIXE instruments Teams have designated leaders Quarterly meetings at SLAC with leaders Start weekly teleconferences soon Yearly general meeting (Oct) Web site is up May 10, 2005 PIXE Project status John Arthur jarthur@slac. stanford. edu

$millions Proposed PIXE funding profile Possibility of some funding in 2006 Total = $50 M-$60 M May 10, 2005 PIXE Project status John Arthur jarthur@slac. stanford. edu

Summary The funding profile constraints on the PIXE project, along with the LCLS schedule, indicate that a phased approach is needed Two instruments in Phase 1, two in Phase 2, 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 May 10, 2005 PIXE Project status John Arthur jarthur@slac. stanford. edu
