LCLS Photon Systems ETC and Methodology John Arthur LCLS Photon Systems Manager LCLS Photon Systems Schedule Overview Milestones ETC Risks
Photon Systems Areas • Front End Enclosure – • Underground facility for X-ray diagnostics and mirrors • Far Experimental Hall – Cavern for 3 experimental hutches • Near Experimental Hall – Sub-basement facility for 3 experimental hutches • X-Ray Transport Tunnel – 200m tunnel to transport X-rays to FEH
Photon Systems • WBS 1.05, 2.05 • X-ray Transport, Optics, Diagnostics (XTOD) • Group located at LLNL, Donn McMahon, CAM • Transport the x-ray beam, in vacuum, to experimental stations • Condition the x-ray beam, with attenuators and apertures • Analyze the x-ray beam, with sophisticated diagnostics
Photon Systems • WBS 1.06, 2.06 • X-ray Endstation Systems (XES) • Stefan Moeller, CAM • Provide basic infrastructure required for experimenters • Build instrument for Atomic Physics experiments • Advanced x-ray detector R&D
Photon Systems • WBS 1.02.03, 1.06.04 • Injector laser and XES laser systems • Bill White, CAM • Coordinate laser design and acquisition throughout LCLS • Injector laser work nearly complete
Photon Systems • WBS 1.05.02, 1.06.02 • X-ray Area Controls and Data Acquisition • Gunther Haller, CAM • Controls and DAQ hardware, cables, and software for the X-ray experimental area
Photon Systems • WBS 2.01.01.05, 2.01.01.06 • X-ray Commissioning Management • John Arthur, CAM • LOE manpower for 2 LCLS Physicists managing X-ray commissioning • WBS 2.06.03 • X-ray Commissioning • Hal Tompkins, CAM • LOE manpower for SLAC and LLNL personnel during X-ray commissioning process
System Design Management • Design process, included in Project P3 schedule • Interface Control Documents specify which group has responsibility for each system • Physics Requirements Documents are written by the LCLS Physics group specifying subsystem needs • Engineering group holds Design Reviews, and writes Engineering Specification Documents to detail how each PRD is to be satisfied • Physicists and Engineers approve component assembly and testing prior to installation
LCLS Installation and Commissioning Time-Line X-ray tunnel/FEH Install LTU/Und/Dump Install FEH X-rays milestone CF Early Occupancy Flux milestone CD-4 (7/30/10) FEE/NEH Install S O N D J F M A M J J A S O N D J F M A M J J A S O N D J F M A M 2007 2008 2009 2010 PPS PPS LTU/Und Commissioning Tunnel/FEH Commissioning Linac/BC2 Commissioning Linac/BC2 Install FEE/NEH Commissioning
Major Startup Activities • Commission FEE 6/09 - 8/09 • FEE flux measurement 7/09 • Commission NEH 8/09 - 9/09 • Commission tunnel/FEH 11/09 - 2/10 • X-rays in FEH 2/10
Photon Systems Cost Estimation • Installation costs • Based on experience in 2006 Injector installation • Hardware install estimate done top-down and bottom-up • Cable plant install estimated using R.S. Means • Fabrication/procurement • Costs based on quotes and experience with similar types of prototypes at SLAC and LLNL • Engineering and Commissioning • Timetable for completion well understood
Photon Systems ETC 43% done Commissioning still to come
Risks • Late changes to design requirements • Atomic Physics design not finalized • Radiation Physics requirements not final • <$200k, <4mo impact • Mitigate through formal design process • AMO design will be finalized in 3 months
Risks 2 • Offset mirror system • Mirrors are specialized long-lead procurements • Precision mirror controls still in development • <$300k, <6mo impact • Mitigate through generous schedule
Summary • XTOD is in procurement phase, XES still in design • XTOD and XES have suffered delays due to CR • New plan allows recovery with extended project, phased completion • Risks to major project milestones are low
