New responsibilities in Linac and Undulator

Jose Chan is the new Cost Account Manager for LCLS Injector and Linac Systems, taking over from Eric Bong.

Geoff Pile is the new Cost Account Manager for Undulator Systems at ANL, taking over from Steve Milton.


Injector Accelerator Readiness Review


Injector Accelerator Readiness Review

Safety Assessment DocumentThe 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.

’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 BSYCoordinated through the AD downtime scheduleIRR 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. See breakout talks


’08 Installation LTU/Undulator/Dump

Readiness for early occupancy held at Nov. 1, 2007Begin installation with:

MetrologyBeamline supportsCable 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.See breakout talk


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 See G. Pile’s talk


Undulator vacuum chamber - 4-Weld Design

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.

Early 4-Weld prototype

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.

See breakout talk


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.
