FY2009 details
  • Now-March 2009
  • Install FEE components, FEE PPS, NEH PPS
  • March/April 2009
  • FEE/NEH safety review, PPS certification
  • May 2009
  • First light to FEE
  • May-June 2009
  • Install AMO instrument in NEH Hutch 1
  • July 2009
  • AMO instrument readiness review
  • First light to NEH (Hutch 1 only)
  • September 2009
  • First LCLS User operation with AMO instrument

LCLS X-ray operations plan
500-700 hrs in FY09, with 1 instrument (month of
Sept 2009) 4000 hrs in FY10, with 2-3 instruments
(Oct-Dec 2009, Mar-Sept? 2010) 5000 hrs/yr by
FY14, with 6 instruments X-ray operations
scheduled in blocks of a few months or more, with
periodic (every 2 weeks?) brief (2 days?)
interruptions for machine studies Typical
experiment will last for about 2 weeks

Experimental Facilities Division Tasks
  • Manage safe operations in LCLS experimental areas
  • Manage LCLS user program
  • Maintain and upgrade X-ray instrumentation
  • Enable good user science initiate in-house
    research

LCLS Offset Mirror Systems
800-2000 eV to Hutch 1
HOMS Hard x-ray Offset Mirror System
SOMS Soft x-ray Offset Mirror System
insertable
800-2000 eV to Hutch 2
insertable
2000-25000 eV to Hutch 3-6

AMO Instrument
Optimized for studying the interactions between
FEL X-ray pulses and simple samples atoms,
molecules, clusters
beam
12
Other LCLS instruments
  • SXR Soft X-ray FEL studies of condensed matter
    (dynamics of phase transitions, imaging of
    nanoparticles)
  • XPP Hard X-ray scattering studies of
    laser-excited states
  • XCS Hard X-ray coherent scattering studies of
    dynamics
  • CXI Flash imaging of nanoparticles and molecules
  • MEE Studies of materials in extreme environments
    (high temperature, pressure)

13
LCLS User Program
  • Goal safe, efficient operation promoting the
    best science
  • LCLS will be a DOE-BES User Facility
  • Access through proposal/review process
  • LCLS scientific staff frequently collaborate with
    users, also maintain independent research
    programs

14
Current XFD Priorities
  • Installation in FEE, Hutch 1
  • Begin User program
  • First proposals in, review underway
  • Seeking User program manager
  • Form Safety program
  • Working with ASD to form complementary structure
  • Seeking XFD Safety Officer
  • Augment scientific/support staff

15
Summary
  • XFD is a new department at SLAC, will run LCLS
    X-ray experimental facilities
  • XFD will be the interface between LCLS and the
    world user community
  • Will nurture creation of LCLS instruments, then
    manage them
  • Goal safe, efficient operation promoting the
    best science
