5. The Interface between LUSI and LCLS
LCLS builds hutches and common infrastructure
LUSI builds instruments in the hutches

6. LCLS is providing infrastructure for experiments
What LCLS will provide
LCLS is constructing the Halls and Hutches in which LUSI instruments will live
Includes lighting, HVAC, service electrical outlets
Includes electrical, water, air interface points
LCLS is providing infrastructure for experiments
Includes network, timing, MPS, 120Hz data interfaces
Includes PPS
LCLS X-ray instrumentation will be available for use by experiments
FEE attenuator, diagnostics available for user control
LCLS prototype 2d detector available for experiments

7. Formalizing the interface
Details worked out through discussion
LUSI-LCLS Integration Working Group
LUSI-LCLS Project Coordination
Details recorded in Interface Control Documents
Define and describe interface points (flange, junction box) between LUSI and LCLS or other SLAC departments

8. Formal coordination methods
The LUSI-LCLS Integration Working Group
Defines the interface between LCLS and LUSI
Resolves issues overlapping this interface
Formalized with Interface Control Documents
Finds common solutions to common problems
Experimental instrumentation, diagnostics
Standardization where appropriate
Members from LUSI and from LCLS Photon Systems

9. Integration Working Group issues
Experimental data flow and interface standards
Formed LCLS/LUSI controls working group
Defined expected data flow rates at LCLS
Defined standard interface for detectors at LCLS
Working to define standard specifications for data handling
Far Experimental Hall optimization
Defined locations of LUSI instruments
Created specifications for FEH hutches
Working with LCLS facilities to optimize FEH hutch design
Standards for common systems
Established an integrated vacuum controls system
Established common understanding of survey practices and accuracy for installation

10. More formal coordination methods
LUSI-LCLS Project Coordination Meetings
Coordinates use of LCLS Engineering resources
