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

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

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

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

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

More formal coordination methods LUSI-LCLS Project Coordination Meetings Coordinates use of LCLS Engineering resources Resolves administrative issues Members: T. Fornek, J. Arthur, J. Galayda
