9. 9/22/04J. Welch, LCLS Commissioning Worskhop, SLAC Startup 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

10. 9/22/04J. Welch, LCLS Commissioning Worskhop, SLAC End 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.

12. 9/22/04J. Welch, LCLS Commissioning Worskhop, SLAC Phase I Demonstrates Bunch compression and bunch length control Orbit control and stability Xray diagnostics functionality SR measurement capability Beam collimation and radiation protection

13. 9/22/04J. Welch, LCLS Commissioning Worskhop, SLAC Phase II Performance Goals

14. 9/22/04J. Welch, LCLS Commissioning Worskhop, SLAC Phase 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,…
