Injector Accelerator Readiness Review
Safety Assessment Document
The LCLS SAD for Injector Commissioning was
approved Jan. 24th.
Accelerator Readiness Review (ARR)
The ARR for Injector Commissioning was held
October 31st.
The committee (in part) reconvened March 14th.
The four pre-start items were cleared when the ARR
report was released.
Four comments from the SSO were also addressed.
Approval to operate was given April 4th.

Injector Commissioning
Injector Commissioning is
underway.
Commissioning has been
impeded by faulty hardware
Problems with profile
monitors, toroids, FC
Working on improving
QA, in the shops, with
vendors and during
installation.

’07 Downtime Installation
Sept., Oct., Nov. 2007, a very tight schedule.
Installation of BC2 and L3, not L2.
Installation to support BTH-West
Cable plant installation through the BSY
Coordinated through the AD downtime schedule
IRR held March 16th.
Kicker magnet design is still ongoing.
Cable plant inst. schedule is tight.
Scheduling and coordination between the
different disciplines will be vital.

’08 Installation
LTU/Undulator/Dump
Readiness for early occupancy held at Nov. 1, 2007
Begin installation with:
Metrology
Beamline supports
Cable plant
Installation scheduling to be coordinated
by R. M. Boyce
Installation contracts need to go to bid this summer.
Need to complete designs to support these.

Undulator Systems Components
Quadrupole magnets on order.
Beam Finder Wire going to procurement.
Wire card a SLAC responsibility, design underway.
Support/Mover system going to procurement.
RF Beam Position Monitor in development.
Prototype being brazed.
Vacuum Chamber – next slide
These systems are all near the critical path.
WPM/HLS FDR was held March 22nd

Undulator vacuum chamber - 4-Weld Design
Early 4-Weld prototype
Two competing designs were
carried to the prototype stage.
Review of the Undulator Vacuum
Chamber Design Options, Feb. 22nd
The 4-Weld design was selected to
remain the baseline.
2 full size prototypes have been produced and tested.
Vacuum properties, mag. permeability,
surface coating process, look good.
Fabrication schedule identified as a problem.
Ordering materials now, preparing the fab. bid package

Undulator Magnetic Measurement
35 undulators have been accepted at the vendors.
20 undulators are at SLAC.
All undulators will be at SLAC by July.
The MMF is in a production mode, but behind schedule.
3 undulators finished magnetically, but not RFI.
1 undulator in fine tuning, 1 in rough tuning.
Production rate is approaching 1 per week.
Learning to deal with the exceptional cases.

Issues
The ’07 downtime Linac installation schedule is very tight.
Hardware availability is being closely monitored
Kicker magnet, cable plant, are concerns
Controls checkout (last) is at risk.
The Undulator vacuum chamber is still on the critical path.
This schedule is being pushed.
RFBPM production schedule is close to critical.
The MMF is in production.
Need to solidly demonstrate throughput.
