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.

Phase II DemonstratesPhase II Demonstrates
• SASE FEL process is working • Requires
– FEL quality orbit straightness and stability
– Good linewidth
– Good emittance
– High bunch current
– Gain length measurements
• Areas of physics concern: CSR, instabilities, wakefield effects, new physics effects,…
