Title: X-ray Overview


1
X-ray Overview
John Arthur LCLS Photon Systems Manager
  • XTOD current status
  • XES current status
  • Schedule to first experiments
  • Coordination with LUSI
  • Transition from project to facility
  • Beyond the LCLS baseline

Status in June 2008
  • XTOD is assembling instruments at LLNL
  • All mirrors have been ordered
  • Soft X-ray mirrors arriving meet figure spec
  • XES is working on final designs
  • Stoppers and doors are being built
  • 2d detector plan is updated prototype under test
    at Cornell, SLAC working on packaging and
    interface to DAQ

FEE Diagnostic Hardware Status
  • Fixed Mask / Slit
  • In house, Integrated testing
  • Attenuator
  • Under assembly
  • Gas Detectors
  • In house/integrating
  • Thermal Sensor
  • Vessel on order
  • Sensors in fabrication
  • Direct imager
  • Vessel on order
  • Cameras, scintillators, filters in house
  • K monochromator in final design
  • Pop-in Monitors in design
  • Controls
  • 4 of 5 FY08 FEE racks complete

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
