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

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
