responsibility for each system
Physics Requirements Documents are written by the LCLS
Physics group specifying subsystem needs
Engineering group holds Design Reviews, and writes
Engineering Specification Documents to detail how each PRD is
to be satisfied
Physicists and Engineers approve component assembly and testing
prior to installation

Photon Systems Cost Estimation
Installation costs
Based on experience in 2006 Injector installation
Hardware install estimate done top-down and bottom-up
Cable plant install estimated using R.S. Means
Fabrication/procurement
Costs based on quotes and experience with similar types of
prototypes at SLAC and LLNL

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
Risks to major project milestones are low
