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 (PRD’s) (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 (ESD’s) (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.
