1LCLS Photon Systems ETC and Methodology
John Arthur LCLS Photon Systems Manager
- LCLS Photon Systems
- Schedule Overview
- Milestones
- ETC
- Risks
2Photon 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
3Photon 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
4Photon 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
5Photon 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
6Photon 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
7Photon 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
8System 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
9Delay work from FY08 to FY09

11Major 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

12Photon 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
13Photon Systems ETC
43 done
Commissioning still to come
14Risks
- 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
15Risks 2
- Offset mirror system
- Mirrors are specialized long-lead procurements
- Precision mirror controls still in development
- lt300k, lt6mo impact
- Mitigate through generous schedule
16Summary
- 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
