• LCLS Functional Specifications Overview
• GRD/PRD/ESD/ICD Index
• PRD 1.4-001

LCLS Functional Specifications

• LCLS needs some TLAs
• LCLS Physics Parameters Database (PPD) (Nuhn)
• High-level database that contains all operating
  parameters for the LCLS. Web-available,
  maintained through the Project Office (Nuhn)
• LCLS Global Requirements Document (GRD) (Galayda)
• A single high-level document that specifies the
  performance requirements for the LCLS. Provides
  an overview of the LCLS requirements and its
  global functional goals and requirements need by
  the LCLS Systems to meet the global functional
  goals.
• LCLS Physics Requirements Document (PRDs)
  (System Physicists)
• System-level documents that specify the
  performance requirements for each LCLS System.
  Provide the functional goals and requirements
  needed by each LCLS Systems to meet the GRD.
• LCLS Engineering Specification Documents (ESDs)
  (System Managers)
• System-and/or component level documents that
  specify the design-to. Provide the functional
  goals and requirements needed by each LCLS System
  to meet the GRD and PRDs.
• LCLS Interface Control Documents (ICDs) (System
  Managers)

Conclusions

• Requirements, Specifications and Interface
  Control Documents are being produced to aid the
  LCLS design and construction process.
• These documents are available from the LCLS WEB
  site.
• The main document outlining the requirements for
  the undulator system is PRD1.4-001.
