The first SOMS mirror meets its specification for
long spatial period flatness

• Total budget for long scale curvature is lt 20 nm
  tangential, lt 5 nm sagittal
• - limits intensity asymmetry due to reflections
  to lt 10
• Allocation to fabrication errors was 10 nm
  tangential, 4 nm sagittal
• - contour plot shows SOMS 1 meets this
  requirement

Coordination with LUSI

• Photon Systems working closely with LUSI
• Both managed by J. Galayda
• Close proximity in Bldg 280
• Shared engineering/design resources
• Interface Working Group meets bi-weekly
• Formal relationship set by Interface Control
  Documents

16
Transition from Project to Facility

• Responsibility for operation of LCLS instruments
  and LCLS X-ray science lies with the Experimental
  Facilities Division (XFD)
• Head, responsible for User outreach Jochen
  Schneider
• Deputy, responsible for LCLS science Jerry
  Hastings
• Responsible for User operations John Arthur

Group includes Photon Systems and LUSI staff
(about 20 today) Growing quickly but thoughtfully
(hiring now)
17
Beyond the initial LCLS configuration

• Policy for outside groups which propose to add
  instrumentation to the LCLS facility
• Must offer a significant addition of general
  utility to LCLS
• Must get support of LCLS (with evaluation by SAC)
• Then group and LCLS negotiate with funding
  agencies
• Then group and LCLS decide final layout and
  timeline, sign MOU
• Some access priority can be negotiated, within
  limits which guarantee plentiful access by
  general users
• All new instrumentation reverts to LCLS
  ownership/management after early operation

18
First example of addition to LCLS

• SXR instrument Soft X-ray Materials studies
• Consortium led by Anders Nilsson (SLAC/Stanford)
  and Wilfried Wurth (CFEL/Univ Hamburg)
• Institutions Stanford, Univ Hamburg, LBNL, BESSY
• Monochromatic soft-X-ray line to complement AMO
  line
• No end station in initial configuration
  (consortium will loan)
• Fast-track schedule operation in late 2009
• Status preparing Design Report for LCLS review
  in July
• If approved, get MOU by September

19
Where to put SXR?
Plan 1, with AMO in Hutch 2
Plan 2, moving AMO to Hutch 1

Summary

• XTOD is building instruments at LLNL XES is in
  final design phase
• This is a busy time for both groups
• The schedule to reach early science in July 2009
  is tight, though risks to CD-4 milestones are
  very small
• LCLS is transitioning from project to facility
• SXR instrument is first example of a proposal for
  additional capability beyond LCLS baseline
