Title: LCLS Photon Systems ETC and Methodology


1
LCLS Photon Systems ETC and Methodology
John Arthur LCLS Photon Systems Manager
  • LCLS Photon Systems
  • Schedule Overview
  • Milestones
  • ETC
  • Risks

2
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
3
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

4
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 RD

5
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

6
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

7
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

8
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

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

12
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

13
Photon Systems ETC
43 done
Commissioning still to come
14
Risks
  • Late changes to design requirements
  • Atomic Physics design not finalized
  • Radiation Physics requirements not final
  • lt200k, lt4mo impact
  • Mitigate through formal design process
  • AMO design will be finalized in 3 months

15
Risks 2
  • Offset mirror system
  • Mirrors are specialized long-lead procurements
  • Precision mirror controls still in development
  • lt300k, lt6mo impact
  • Mitigate through generous schedule

16
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
