Recommendations from Oct 2006

Put effort into design of critical x-ray optics components (mirrors and thin crystals)

Make LCLS Photon Systems and LUSI work together to optimize designs and commissioning plans

Putting both recommendations into practice

Effects of 2007 CR on XTOD

Procurements and some design effort were delayed

New plan was developedCommissioning optics in FEE ready for first lightBeam transport to NEH ready by late FY2008All work on Tunnel and FEH delayed until FY2009All work finished by early FY2010

LUSI-LCLS Integration Working Group

Define the interface between LCLS and LUSI

Resolve issues overlapping this interfaceFormalize with Interface Control Documents

Find common solutions to common problemsExperimental instrumentation, diagnostics

Standardization where appropriate

The Working Group was created by Keith Hodgson and John Galayda to:

Summary

XTOD and XES are still in design phase, though XTOD is

moving into procurement and XES will follow soon

FY2007 continuing resolution forced some delays,

extension of project

Technical issues are being resolved with no big problems

Should be ready for installation starting 11-07

FEE, NEH ready in FY2009, FEH ready in FY2010

Coordination with LUSI is going well, has been formalized
