e-Beams Systems Wrap-up Outline Injector Systems Linac Systems Undulator Complex ARR Undulator Systems Lessons Learned Summary

Injector Systems Emittance Enhancement (Heater) is complete and in successfully tested. Research into its effectiveness is ongoing.

Injector Systems Injector is now in the hands of ASD Operations Accelerator Systems Division Area Physicist: Axel Brachman Area Manager: Patrick Smith Gun cathode was replaced in July ’08, QE has been stable at 4x10-5 near spec. Drive laser availability has been excellent, >99%

Linac Systems LCLS Linac commissioned and operational Accelerator Systems Division Area Physicist: Franz-Josef Decker Area Manager: Tom Graul LCLS Risk Registry items Emittance measurement in sector 24 On the AIP list Linac BPM upgrade Electronics now in fabrication

LTU-Dump installed and being commissioned Linac Systems LTU-Dump installed and being commissioned Some remedial installation planned Photon diagnostics in the dump area Toroids to assure beam delivery to the dump. Designated ASD Area Physicist: Rick Iverson Area Manager: Kathy Burrows Beam Transport Hall

Undulator Complex ARR Accelerator Readiness Review for the Undulator Complex (LTU-UND-EBD) was held 12/2/08-12/4/08 Frank Kornegay chair Pre-start items cleared 12/12/08 SSO approval 12/12/08 Beam to main electron dump 12/13/08 ARR post-start items have now been cleaned up

Undulator Systems Undulator Installation 25 Undulators are installed, 3 more RFI 33 will be installed by the end of June All hardware from ANL received The LTT needs to be relocated at SLAC The remainder of the ANL Beam Loss Monitors need to be fabricated.

Long Term Test at ANL

Undulator Systems Designated Accelerator Systems Division Area Physicist: Heinz-Dieter Nuhn Area Manager: Mike Zurawel Will cycle two Undulators per month through MMF to check for stability.

e-Beams Systems Wrap-up Lessons Learned If hardware and controls are not effectively checked out in the lab prior to installation, then problems are not found until commissioning. Design reviews are the best management tool for collaboration with remote partner laboratories.

e-Beams Systems Wrap-up Summary E-beams Systems Commissioning should be complete next month. 33 Undulators installed Photons into FEE Outstanding items Undulator Installation (TEC) Undulator systems commissioning (OPC) Long Term Test at ANL (OPC)
