• 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

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
