LCLS Photon Systems ETC and Methodology
John Arthur LCLS Photon Systems Manager

• LCLS Photon Systems
• Continuing Resolution effects
• The new ETC
• Risks

LCLS Photon Systems Responsibilities

• XTOD
• Transport the x-ray beam, in vacuum, to
  experimental stations
• Condition the x-ray beam, with attenuators and
  apertures
• Analyze the x-ray beam, with sophisticated
  diagnostics
• XES
• Provide basic infrastructure required for
  experimenters
• Build instrument for Atomic Physics experiments
• Advanced x-ray detector RD
• Laser
• Coordinate laser design and acquisition
  throughout LCLS

XTOD Status

• Design phase ending
• Layout details almost complete
• Nearly all technical components through
  Preliminary Design Review phase
• Procurements have begun
• LLNL team is working well with SLAC

4
XES Status

• Now in design phase
• AMO instrument design going well
• 2-d detector development going well
• Controls area much improved
• PPS stopper design through PDR

5
Effects of the CR

• CR caused delays and inefficiencies in FY07
• Design reviews were delayed due to uncertain
  scope, schedule and busy managers
• XTOD procurements were delayed in FY07

6
The New Plan Big Picture

• Phased approach to X-ray beamline delivery
• NEH in FY09, FEH in FY10
• Diagnostics ready for first light in May 2009
• Do first AMO experiments in FY2009
• Instrumentation ready by end of July 2009
• Delay as much work as possible until FY09-FY10
• Within the constraints given above

7
The New Plan Details

• Delay many AMO procurements until FY09
• Pushes AMO instrument availability to 7-09
• Delay some FEE work until FY09
• Deliver light to NEH 7-09
• Puts this XTOD work on the project critical path
• BUT get FEE diagnostics ready for first light
  (5-09)
• Requires some procurements in FY08

8
The New Plan Details 2

• Ready to support LUSI in NEH in late FY09
• Hard X-ray line to Hutch 3 will be complete
• Get authority to begin exptl operations
• Experiments in NEH in FY09
• AMO and LUSI experiments

9
XTOD near milestones (Level 3)

• Award High-Energy mirror PO 12-2007
• First instrument ready to ship to SLAC 3-2008
• Start FEE installation 7-2008

10
XES near milestones (Level 3)

• AMO Preliminary Design Review 11-2007
• 2D detector review 11-2007
• Award Laser system PO 11-2008
• Start installation in NEH 1-2009

Photon Systems New ETC

• Increases
• Extended schedule adds manpower cost (2000k)
• Revised controls/DAQ plan shows increases (2400k)
• Decreases
• Savings in technical system costs (-900k)
• Savings in transition to operations (-1500k)
• Net TEC increase of about 3M

Risks

• FY08 budget crunch - some XTOD work might be
  delayed further (from FY08 to FY09)
• One could delay some FEE and NEH controls work
  (300k total)
• This would add slight cost risk and significant
  schedule risk for experimental work in FY09
• XTOD and XES work is fund-rate limited

15
Risks 2

• Offset mirror system
• Mirrors are long-lead procurements (schedule
  risk)
• Precision mirror controls still in development
  (cost and schedule risk)

16
Risks 3

• Radiation Physics may require late changes
• Novel source presents novel safety hazards,
  requires much analysis which is not yet finished
• Additional shielding may be required (cost and
  schedule risk)

17
Preparation for good news Possible X-ray
speedups
If more FY08 funds become available, one could

• Speed up controls and stands for FEE (1000k)
• Speed up X-ray monitors in FEE (300k)
• Speed up NEH controls and motors (450k)
• Speed up XES laser system (340k)
• Speed up AMO focusing mirrors (115k)

18
Summary

• XTOD and XES have suffered delays due to CR
• XTOD is in procurement phase, XES still in design
• New plan allows recovery with extended project,
  phased completion
• Should be ready for early occupancy of exptl
  areas
