  19. XTOD work flow will follow ISMS practices for each WBS element WBS Dictionary LCLS Physics Requirements ICDs IWS (Integrated Work Sheet) is LLNL wide e-form for documenting ISMS for each work package: Scope Hazards Controls Roles (RI…) Responsibilities Training Signoff Hardware Installation Operations Servicing ERDs Designs Eng. Safety Notes Certified Parts Lists

  20. Short term IWS: Cover Prototype development and testing, offsite and on-site: Gas Attenuator prototype in B132 (in progress) Direct Imager B272, SSRL X-Ray Box tests … Drive Laser R&D, B480 Add SLAC personnel to IWS + training Long Term IWS: Cover Each WBS deliverable: Fabrication & Assembly Bench testing Transport to SLAC Installation Commissioning Operation Servicing IWSs for LCLS XTOD Prototypes and WBS Elements

  21. FY05 Goals • Mechanical and Vacuum • Cost estimate and Engineering Plan through NEH • IWS's, ICD's, and ERD's • Detailed plans / parts for prototype: • Gas Attenuator, Control system tests, concepts for monitoring beam and attenuation • Total Energy, 1 pixel • Direct Imager, for 826 eV tests at SSRL • Monte-Carlo simulations of FEE instruments and alignment • Document in ERDs • Apertures, Expected light levels, Reflectivity, …
