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

ASD responsibility XFD responsibility Undulator Hall XFD responsibility Near Experimental Hall Shield wall between Electron Dump and FEE Far Experimental Hall

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

The LCLS X-ray Beamline X-ray transport tunnel Far Experimental Hall Hutch 1: AMO Instrument Near Experimental Hall Front End Enclosure

Diagnostics and Offset Mirrors in the FEE Solid Attenuators Gas Attenuator Thermal Sensor Beam Direction Slit Gas Detectors K-Mono 5 mm collimator Direct Imager (Scintillator) FEL Offset Mirror Systems

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

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)

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

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

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
