X-Band System (LX)
Eric BongLCLS FAC Injector-Linac System Overview [email protected] 27, 2005
BC1 Articulation Region Design
Beamline segment from X-Band system to structure BC1-Out diagnostics section.
Compressor articulation in fabrication at outside vendor. Fabrication halted and restarted to modify chamber to provide sufficient aperture for BLM.
Manget design reviewed at vendor.
Compressor diagnostics incomplete. Manpower added.
Most risk in diagnostics package; collimator, BPM & OTR.
Eric BongLCLS FAC Injector-Linac System Overview [email protected] 27, 2005
BC1-Out Region Design
Beamline segment from BC1 compressor articulation to structure Li21-2b.
Downstream emittance section layout complete. Uses existing wire scanner, quadrupole, stopper and BPM designs with support stands modified to mount on accelerator lightpipe.
Collaboration with UCLA on single shot bunch length monitor dropped. Design to be done at SLAC. Two devices to be built. See later talk. Design most at risk. Relative bunch length measurement required for RF feedback.

Conclusion
Progress is being made toward completing beamline and component design for 2006 installation supporting January 2007 commissioning but with some riskPriority of design activities must be placed on components to be installed in Linac Housing during 2006 downtimeInjector Vault water system design and installation must be expedited
