Injector Wall Region

Spans through shielding walls separating Injector Vault form Linac Housing.October 2005 installation included pipes through walls and stopper. 2006 installation of wire scanners, profile monitors and quad on Linac side of shielding wall.Device designs complete and in fab or on hand.Low risk for 2006 install.

Eric BongLCLS FAC Injector-Linac System Overview [email protected] 27, 2005

Injector Insertion/SAB Region

Support modal analysis complete stiffened as result to meet vibration tolerance.Common OTR optics design late. Special OTR at spect end from ANL. Magnets designs complete. On order or received except spect bend. Chamber designs complete.Second least mature region design.

Eric BongLCLS FAC Injector-Linac System Overview [email protected] 27, 2005

L1 RegionAll detail drawings complete and part on hand or in fabrication less correctors

Low risk for 2006 installation

Eric BongLCLS FAC Injector-Linac System Overview [email protected] 27, 2005

XL4 Klystron fabrication complete. Waveguide fabrication in progress.Structure support design complete & in fabNeed LLRF, modulator modsVacuum assy install required.Region operation not necessary for ’06/’07 commissioning.

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.

SLAC Engineer and top physics support assigned to BLM project

Injector Vault

Installation of stub columns started.

Water system design critical to commissioning start.

Eric BongLCLS FAC Injector-Linac System Overview [email protected] 27, 2005

Injector Waveguide Design

Installation penetration-wall October ’05

Installation Vault & Gallery starting Spring ’06.

Waveguide design complete, fabrication underway. Waveguide supports in final design.

3-D Layout integrated into Injector system assembly.

Gun and structures fed from Li-20-6, 7 & 8 klystrons, T-Cav fed from Li-20-5d structure exhaust.

Old waveguide runs have been disconnected from Klystrons.

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
