Recommendations from April 2007
Get mirrors spec’ed and ordered asap
Refine commissioning plan
Get a good system in place, then make it better
Response: Trying to follow recommendations.
However, the new plan has significantly affected
the X-ray schedule

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

The New Plan: Big Picture
Try to move as much budget as possible beyond FY08,
consistent with first light in May 2009, experiments later
in FY09
Phased approach to X-ray beamline delivery
NEH in FY09, FEH in FY10
Diagnostics ready for first light in May 2009
First AMO experiment ready late July 2009
Remove as much schedule float as possible

The New Plan: Details
Delay many AMO procurements until FY09
Pushes AMO instrument availability to 7-09
Delay some FEE work until FY09
First light in FEE 5-09
First light in NEH 7-09
Puts this some XTOD work on the project critical path

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 expt’l operations
Experiments in NEH in FY09
AMO and LUSI experiments

Preparation for good news:
Possible X-ray speedups
If more FY08 funds become available, we could:
Speed up controls and collimators 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)
Maybe advance first light date by 1-2 months

Summary
XTOD is in procurement phase, XES still in design
XTOD and XES have suffered delays due to CR
New plan allows recovery with extended project, phased
completion, some procurement delays
Aiming for first light 5-09, first experiments in NEH shortly
thereafter
Working closely with LUSI
