4. LCLS X-ray operations plan
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

11. 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
