Injector System Installation Drive laser transport tube installed 10/14/05: The ceiling in the injector vault The first piece of installed LCLS beamline. Laser bldg. construction

October ‘05 Injector Installation Installed Injector beamline and waveguide in vault, to mate to Spring install schedule.

Injector/Linac Installation Access to the Injector vault. Laser facility construction through 2/06 Injector vault available for installation 3/06-11/06 Aug.- Nov. 2006 accelerator down Install to end of Injector spectrometer Install Linac to Bunch Compressor 1 dump BC1 bunch length (feedback) monitor is at risk PPS connection to SLAC Linac & certification

Injector/Linac Commissioning Commission drive laser 6/06-11/06 Needs laser safety system certification The design is well along, FDR 3/06 Coordinate with Injector installation in vault Dec. 2006 to Aug. 2007 Commission electron beam through Injector and BC1 Occurs during B-factory operations. Need Injector SAD, ARR by 11/06

PPS/BCS Development and Integration Manager Mike Saleski Arrived 1/1 Responsible for PPS and BCS LCLS-wide System design and reviews Radiation shielding design Stoppers and stopper systems’ design Approval by the SLAC citizen committees

Injector Accelerator Readiness Review (1) Design Reviews Component and System PDRs and FDRs are being conducted following LCLS guidelines. SLAC Citizen’s Committees will participate in the review process, following normal SLAC practice. Commissioning Plan Paul Emma heads the LCLS Commissioning planning team, developing a detailed plan and schedule for the process.

Injector Accelerator Readiness Review (2) Safety Assessment Document (SAD) LCLS will be integrated into the SLAC Linear Accelerator Facility SAD. SLAC is coordinating the revision of the SAD. The LCLS Injector sections will be incorporated by June 2006. Accelerator Readiness Review (ARR) LCLS ARR for Injector Commissioning will begin September and be completed in November 2006. LCLS Commissioning/Operations Working Group The Working Group’s role is to coordinate the execution of the tasks noted above and assure the plan is met.

New Head of LCLS Controls Hamid Shoaee Arrived 1/23 LANCE Controls Group Leader Recent experience with SNS Linac control system and the SNS Controls and Automation group Previously in the SLAC Controls Dept.

Controls PPS Diagnostics Timing A PLC based system, new for SLAC, an increased burden for approval. Injector PPS system, PLC logic and PLC implementation design reviews are scheduled, to be complete by June. Additional experienced manpower from APS, new hire at SLAC. Diagnostics Stripline BPM system, charge monitor toroids, now under control with enhanced participation from SLAC Controls personnel. Timing PNET VME timing board is under test, operating well. Diamond timing system hardware is here to test integrated operation with the PNET board. Increased participation from SLAC Controls personnel

Undulator At APS the Undulator system components are being designed and fabricated. Undulator components, 1st art. assembly, on order RF BPMs under development for beam testing Good progress on Quads, Vac. chamber, BFW, motion At SLAC the schedule for Undulator girder assembly and precision alignment is under revision Delivery sequence, available space, MMF capacity
