New responsibilities in Undulator
Jose Chan is the new Cost Account
Manager for Undulator integration at SLAC,
taking over from Rodd Pope.
Unifying Undulator and Linac integration
and installation for seamless design and
planning through the rest of the project.
We have instituted a number of weekly video meetings
with ANL.
RFBPM, Vacuum, BLM, Controls, Quadrupoles,
Supports,
We have started quarterly Undulator collaboration
meetings to ensure coordination.
1st meeting Sept. 25-28

Recent Injector/Linac Progress
LCLS Injector, and Bunch Compressor 1
Installed and commissioned
Commissioning goals achieved
Corrections and repairs identified
BC1 magnet field improvement is ongoing
Systems declared operational

Recent Injector/Linac Progress
Bunch Compressor 2 and Linac
The down is under way, good progress made
Mechanical installation complete this week
Controls checkout to start next week
One BC2 dipole had faulty coils. They are
being reworked, but will likely miss the down
The schedule is tight, PPS cert. will interfere
Some installation (BC2 dipole) will spill over
Commissioning can proceed as planned
BC2 commissioning schedule is generous

Undulator Magnetic Measurement
All undulators have been accepted from the vendors.
39 are at SLAC, 1 is at ANL.
The MMF is in a production mode,
15 undulators are finished magnetic tuning and
fiducialization.
2 in fine tuning
1 in rough tuning
2 have been deferred for rework
Production rate is approaching 1 per 6 working days.

Undulator System Progress
Undulator Support/Movers have begun arriving at SLAC.
1 assembly at ANL, 8 at SLAC, +5 to be shipped this week.

Undulator System Progress
Undulator quadrupole magnets
The order has been placed with Everson-Tesla
The first two 1st article quadrupoles rejected
The 2nd two 1st articles arrive at Argonne this week
The 33rd magnet arrives at SLAC February 13th

Undulator System Progress
The assembly of the Undulator Girders is on the
project critical path for Undulator commissioning.
Several parts are, or are near, the limiting factor
RF BPM production
The RFBPM performed very well in the 3-BPM test
at ANL.
Fabrication has begun on some parts,
but design is just now finishing.
Prototype fabrication (brazing) was problematic.
The design has been simplified to address this.

Undulator System Progress
Undulator Vacuum chamber
The Stainless Steel ‘4-Weld’ design has been abandoned
due to tight constraints on magnetic permeability.
Three alternate designs were taken up,
Extruded Al design
Clamshell Al design (now halted)
Cu tube design
(now halted)
The extruded Al design is now the baseline.
Interior surface finish is polished and acceptable
Mechanical, vacuum tolerances have been met
Production schedule remains a concern
Being pushed very hard

LTU/e-dump status
Controls and component fabrication for LTU -> dump
installation is proceeding well.
Co-occupancy in December
Metrology, floor drilling, stand installation
Stands RFI in November
Contracts to go out soon for
Floor drilling and stand installation
Cable plant installation
Beneficial-occupancy in March
Most components out for fab., or in the shop

LTU-Und-Dump Commissioning
LCLS Safety Assessment Document is due 7/2008
LCLS Accelerator Readiness Review is needed 10/2008
Systems installed, checked out, signed off by responsible parties.
Safety officers’ signoffs on approvals and installations.
Safety specific systems (Personnel Protection) certified.
Maintenance groups have procedures and training in place.
Procedures in place for Operations, and Operators trained.
Beam Authorization Sheet prepared.
These items are in progress, and being organized by the
Working Group for LCLS Commissioning and Operations
Detailed commissioning schedule and performance goals have been
produced and are maintained by the LCLS Physics group.

Summary
Progress to-date has been good, especially with
Injector commissioning
Progress towards completion of the current
installation is good
Commissioning can proceed as planned
The installation of the rest of the electron beamline
follows the current installation very closely
Undulator assembly is on that critical path.
Components are arriving from ANL
Schedule, Schedule, Schedule!
