Startup Test PlanStartup Test PlanPRD 1.1-002PRD 1.1-002

• Spells out our plan for turning on the LCLS systems. Currently working on rev-1.

• Evolved from "Commissioning Document" discussed at previous workshop.

• The editors continue to welcome your contributions!

Startup PhasesStartup Phases

• Phase I - low beam quality– BBA, radiation reduction, x-ray diagnostics, SR

measurements

• Phase II - high beam quality– low emittance tuning, gain curve measurement,

precision x-ray measurements

• Phase III - transition to operation– Full rep rate, stable operating conditions, full energy

range, finalize operational procedures

End of StartupEnd of Startup

• Startup Plan goes well beyond "Start of Operations" which is met when X Rays are detected at the Far Hall

• At the end of Phase III we leave the machine with operators who are then able to provide users with required beams on a daily basis.
