Linac Downtime Issues
BPM feed-through welding, many leak.
Leak at ceramic, need UHV QC before welding
Late components:
BC1 Instrument package
BLM 11 (BLM 12 will be in)
Toroids (in several locations)
Vacuum chambers in insertion region.
Spool pieces are being fabricated
to be installed temporarily.
Time will be needed to install these components
as they become available.

LCLS Injection
LCLS Insertion region
Critical vacuum
chambers which
may be late.

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 to final bake
RF waveguide needs to go through bake
Gun is in hot test, RF on 10/5
2nd gun is in brazing
then final cold-test, final braze.
Support stands are in the vault ready
except for the GTL table

Injector Installation Issues
Water system needs to be installed,
installation reqs. out,
BPM feed-through welding, toroids
Late:
The GTL stand released to purchasing.
Estimate it will be here 11/16 for installation 11/20.
Laser table installation begins 11/27
The Gun will be ready by then, needed later.
GTL is late, now moving to machining. (next slide)
Working to advance the schedule. What is
competing? What can be sent out? Critical path.

Undulator Systems Design
Quadrupole Order placed, vendor designs, 1st article 2/07
Fixed Support/Mover Final Design Review - September 13/14
Go ahead given for production.
Beam Finder Wire Final Design Review - September 20, 2006
Go ahead given for production of BFW, except wire card.
RF Beam Position Monitor Final Design Review - October 4
Testing program has been interrupted by RF gun failure.
Vacuum Chamber Final Design Review - September 27/28
42" chamber welded, machined, to be coated.
2 other prototypes in hand for QC, permeability measurements.
Plan D design effort initiated at SLAC.

MMF Status
Measurement benches installed and commissioned.
CMM installed and in use.
Quad measurement station operational.
Eight finished undulators are here at SLAC.
Six to eight more to be shipped to SLAC by October 20th
Issues:
Air cond. mixing valve (new) failed. Now repaired.
New breaker panel wiring needed to be worked on.
Compressed air system does not meet spec.
Looking for a work-around.
Need to move to production fine-tuning.

Injector Accelerator Readiness Review
Safety Assessment Document
Draft LCLS SAD for Injector Commissioning under
internal review.
Operating procedures are being written with AD Ops.
Commissioning
LCLS Commissioning Workshop October 9-11
Includes a Commissioning Readiness Review.
Accelerator Readiness Review (ARR)
LCLS ARR for Injector Commissioning scheduled for
October 31st.
Committee members, speakers on board.

Issues
The downtime schedule is very tight.
We got off to a good start.
Not all parts are in hand.
Injector installation will delay commissioning.
Controls checkout (last) is at risk.
The Undulator vacuum chamber is still in the
design/prototype stage.
On the critical path.
Adding engineering resources from SLAC.
The MMF is late and needs attention.
