LCLS Photon Systems Status

1
LCLS Photon Systems Status
John Arthur LCLS Photon Systems Manager

• Technical status and accomplishments
• Response to FY2007 continuing resolution
• LCLS/LUSI coordination

2
Recommendations from Oct 2006

• Put effort into design of critical x-ray optics
  components (mirrors and thin crystals)
• Make LCLS Photon Systems and LUSI work together
  to optimize designs and commissioning plans

Putting both recommendations into practice
3
XTOD Status

• Still in advanced design phase
• Nearly all components at least through conceptual
  review
• Staying on schedule
• About to start major procurements
• Hardware installation can start 11-07
• LLNL team is working well with SLAC

Effects of 2007 CR on XTOD

• Procurements and some design effort were delayed
• New plan was developed
• Commissioning optics in FEE ready for first light
• Beam transport to NEH ready by late FY2008
• All work on Tunnel and FEH delayed until FY2009
• All work finished by early FY2010

7
XES Status

• In design phase
• AMO instrument design going well
• 2-d detector development going well
• Controls area was behind, catching up
• Working with Radiation Physics on PPS items
• Ready for installation starting 11-07

Effects of 2007 CR on XES

• Some design effort was delayed
• New plan was developed
• Safety and controls work in NEH ready late FY2008
• First-stage AMO instrument ready late FY2008
• Work in FEH delayed until FY2009
• Some AMO instrumentation delayed until FY2009
• All work finished by early FY2010

LUSI-LCLS Integration Working Group
The Working Group was created by Keith Hodgson
and John Galayda to

• Define the interface between LCLS and LUSI
• Resolve issues overlapping this interface
• Formalize with Interface Control Documents
• Find common solutions to common problems
• Experimental instrumentation, diagnostics
• Standardization where appropriate

12
Working Group Members

• Jerry Hastings (LUSI)
• John Arthur (LCLS)
• Yiping Feng (LUSI instrument scientist, controls)
• David Fritz (LUSI instrument scientist,
  diagnostics)
• Stefan Moeller (LCLS Endstation Systems Manager)
• Hal Tompkins (LCLS x-ray installation,
  commissioning)
• Other LCLS/LUSI staff as needed

Co-chairs

Issues before the Working Group

• Experimental data flow and interface standards
• Vacuum hardware and controls standards
• Conventional facilities/hutches
• Installation/commissioning

14
Summary

• XTOD and XES are still in design phase, though
  XTOD is moving into procurement and XES will
  follow soon
• FY2007 continuing resolution forced some delays,
  extension of project
• Technical issues are being resolved with no big
  problems
• Should be ready for installation starting 11-07
• FEE, NEH ready in FY2009, FEH ready in FY2010
• Coordination with LUSI is going well, has been
  formalized
