This report provides an update on the ongoing injector and linac installation efforts. Managed by Kathleen Ratcliffe, the project involves major partners from the Mechanical Fabrication Department. Installation work is currently underway in Sector 21 and Sector 20, focusing on the necessary housing and safety systems. Although there have been challenges and delays due to component availability and other issues, preparations are complete, and hardware is ready for commissioning. The team emphasizes effective collaboration and thorough documentation to ensure future success.

  1. Injector / Linac Installation Current Status • Manager-Kathleen Ratcliffe • Project Schedule R.M. Boyce • Major Partner-Mechanical Fabrication Department • Installation Underway!

  2. 2006 Installation Sector 21 Sector 20 Laser BC1 Out Bunch Compressor 1 Vault X-Band Compressor L1 Insertion/SAB Wall

  3. Linac Status • Downtime Installation 8/~20 Weeks of Linac Access • Prep and Removal Complete • Installation Priority • Linac Housing / Return to A-Line Operation January 07 • Vacuum Envelope & All Safety Systems • Injection Vault / Laser Schedule and Controls • SLAC Resources / MFD and Others • Hardware Ready • System Schedule / Commissioning • Good Design, Teamwork, Control

  19. SAB Dipole Gun / GTL Laser Table Gun

  20. Gun-to-Linac area Laser table uv Gun L0a Spectrometer GTL

  21. The LCLS photocathode electron gun

  22. Linac Downtime Issues • BPM feed-through 10-9 He leak • Old problem / New again (~3/23 BPMs On Temporary Hold) • BC 1 Diagnostics • 2/3 Assemblies close with Fab. SLA BPM is probably late for January. • Late components: • BLM 11 (BLM 12 will be in) • Toroids (All Locations / Vendor Failure) • Vacuum chambers in insertion region. (next slide) • Spool pieces are being fabricated to not prevent Commissioning Start. • Scheduled Downtime will be needed to install these components January : March to support current Commissioning schedule.

  23. LCLS Injection LCLS Insertion region Linac beam Vac Chambers late for January Linac integrity needed for ESA program in Jan.

  24. Injector Installation Status • Injector installation has taken second priority to Linac installation. • Injector vault: • Floor and cable plant installed • Injector beamline: • Accelerator structures, L0a ready, L0b in final bake • RF waveguide needs to go through bake • Gun in hot test at Klystron Mfg • 2nd gun is in pre-braze cold-test. • Vault Supports & Tables waiting DB start. • except for the GTL supports & table

  25. Injector Installation Issues • Water system under pressure to make schedule! • 1 BPM in GTL waiting feedthrough resolution. • Late: • Torroids are not delivered from Vendor • The GTL stand is out for quote • Estimate it will be here 11/16 for installation 11/20. • Laser table installation begins 11/27 • The Gun will be ready by Laser Table install. • GTL is late, released for machining. • Working all issues with MFD to expedite schedule. • Improve on 2/15/07 Date.

  26. Some Good Stuff • Good Design with Solid Documentation. • Active Data Base • Interconnect Control • Component Histories • Non-Compliance • Effective Teamwork MFD/MD/KLY/AD • Downstream Linac under design!
