The world's first x-ray free electron laser Pulses of x-ray laser light much brighter and shorter than produced by other x-ray sources Enable new sciences for discovering and probing new states of matter, understanding and
following chemical reactions and biological processes in real time, imaging chemical and structural properties of materials on the nanoscale, and imaging non-crystalline biological materials at atomic resolution
Currently in the project engineering and design phase - operational in 2009
The LINAC Coherent Light Source (LCLS)

Injector, Sector 21 and BC1 Power Systems
Power System PurposeProvide controlled DC power for magnets needed to steer and focus the first LCLS-generated beams
When NeededInstall and test power and control systems during August through November 2006 PEP downtime
Phase 1 Injector commissioning in December 2006 timeframe will entailInitial acceleration from Gun to Spectrometer Dump
Subsequent acceleration from Gun to Tune-up Dump at the end of Bunch Compressor
Cover Three Major AreasInjector, Sector 21 and Bunch Compressor 1

Committee Focus - End Slide
Status
Final design review
Conceptual and Preliminary design reviews already held, albeit informally
Equipment specifications written, hardware ordered, and 80% received
Focus
Degree of system integration
Readiness to support programming
Preparation for accelerator readiness review (test plans)
Unresolved issues
