5. LCLS Project Baseline Shown at 8/10/04 Review ~29.5% contingency on work remaining LCLS is ~30% complete on PED

6. Lehman Review Debrief • Concern expressed about budget/schedule • Conventional Facilities Contingency • Tunneling • FY2005 schedule did not reflect CR • Procurement staffing, schedule • CF Independent Cost Estimate due 15 Oct. • 15 October revised baseline to DOE

7. Schedule Guidance • Show 1 year float to CD-4 • Assume continuing Resolution thru December • Project completion before end of 2QFY2009 • Plan Higher contingency for conventional facilities

8. ESAAB Meeting • 2 November 2004 • CD-2B, complete LCLS Project Baseline • CD-3A, Begin Long-Lead Acquisitions • Prerequisite for approval: • Project Execution Plan • Project Management Plan • Partner Labs’ management must approve

10. Continuing Resolution • No definitive guidance on allocation of PED/R&D • CR limits total year’s allocation of PED to $7.5M • R&D not limited by CR, but by other constraints • DOE might provide >$1M month • $30M Long-Lead acquisitions • New start • $0 under a CR • Stops construction at SLAC and ANL

11. LCLS Experiments • DOE-BES plans to approve and fund a bundle of experiment stations as a “major item of equipment” (MIE) project • Patterned on “Spallation Neutron Source Next Generation” (SING) Instrument MIE • CD-0 imminent • CDR, CD-1 (for the bundle) next summer • Separate CD-2 for each station as designs mature • SSRL does construction management of all

16. Defining LCLS Experiment Stations • Ultrafast Science and LCLS Experiments Workshop 25-26 October 2004 • http://www-conf.slac.stanford.edu/ssrl/2004/workshops.htm • A Workshop in Ultrafast Science and LCLS Experiments at SSRL will be organized on October 25-26, 2004. There will also be a pre-registration reception on Sunday evening, October 24th from 5-7 pm. The tentative schedule for the workshop is a joint session on Monday morning, October 25th. On Monday afternoon and Tuesday morning, there will be breakout sessions for each of the five thrust areas of the LCLS: (1) Atomic, molecular and optical physics, (2) High energy density states of matter, (3) Optical pump-x-ray probe studies in chemistry, biology and materials science, (4) Diffraction imaging of single objects approaching atomic scale resolution and (5) Coherent x-ray scattering for the study of dynamics (X-ray photon correlation spectroscopy). The workshop will end with a joint session on Tuesday afternoon, October 26th. The workshop and breakout sessions will focus on the scientific goals and technical needs of the LCLS experimental end-stations, as well as experimental specifications. This workshop provides an opportunity to all users, including potential future users to participate in building ultrafast science at LCLS by providing input and sharing their scientific ideas. • If you are interested in participating in the atomic, molecular and optical physics breakout session at the meeting please contact Lou DiMauro (dimauro@bnl.gov), Phil Bucksbaum (phb@umich.edu), Nora Berrah (berrah@wmich.edu) or Jerry Hastings (jbh@slac.stanford.edu).  If you are interested in any of the other breakout thrust areas please contact John Arthur (jarthur@SLAC.Stanford.EDU). • For program information see: http://www-conf.slac.stanford.edu/ssrl/2004/lcls_workshop.htm
