Summary

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

4. 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%

5. 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

6. LTU-Dump installed and being commissioned
Linac Systems
LTU-Dump installed and being commissioned

7. 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

8. 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.

9. Long Term Test at ANL

10. 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.

11. 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.

12. e-Beams Systems Wrap-up
Summary
E-beams Systems Commissioning should be complete next month.
33 Undulators installed
Photons into FEE
Outstanding items
