  3. Department Organization

  4. Controls Department support ofcommissioning and operation • Over 20 years of experience maintaining control systems (SLC, PEPII, etc.) • Control Room has detailed, up-to-date list of subsystem responders. • Controls hardware & software support are on-call. • Invasive solutions are scheduled for “Repair” days if not immediately impacting program. • Escalating call-in for items with immediate impact (stopping beam delivery).

  5. Recent Improvement • “Controls Deputy” on rotating week-long shift in the control room, paralleling the physics Program Deputy: • Primary conduit for all controls issues. • Works with operations to get problems categorized and recorded in the maintenance reporting facility (CATER). • Notifies section leads when critical problems arise. • Present at all maintenance meetings.

  6. Hardware: Timing, LLRF, BPMs Profile monitors, Video displays Vacuum, Collimators Movers, Scanners Toroids, Thermocouples Networks Crates, IOC CPUs Software: High-Level applications Networks and computer systems EPICS systems Infrastructure Logging Archiving Alarming Control room GUIs The department covers all electronics and software areas

  7. Timing Beamline Motion Laser Heater OTR Focusing Matlab-based Feedbacks Bunch Length Monitors Injection Laser Special RF Magnets Configurations MPS PPS BCS Specifically LCLS

  8. Documentation and Procedures • Rack drawings and profiles • Cable routing sheets database • Electronic chassis schematic diagrams • Manufacturer drawings and manuals • Safety procedures and work authorization forms

  9. Rack Population Tracking System Building 24 assembly area

  10. The readiness status of all controls racks are reviewed weekly (sheet on SharePoint)‏

  11. From the list of devices to be installed… • Develop racks layout & cable tray design • Generate rack profiles for electronics modules • Identify DC & I&C cabling requirements & document in CAPTAR • Produce installation bid package from CAPTAR and tray designs • Generate installation bid package & award contract • Procure trays, cables, connectors, etc. • Install cable plant and terminate to beam line components

  13. Test Plan and Risk Analysis 13

  14. Formal Power up procedures were developed for each controls sub-system to ensure safe turn-on

  15. LCLS Work Authorization AHA Equipment Lockout Procedures Work Authorizations for non-standard work Checkout and commissioning carried out jointly with operations and physicists User interfaces follow best engineering practices Software version controls Software documentation for users and developers Safety systems follow a rigorous set of procedures in all phases of work Department Practices

  16. Safety Systems organization ensures independence of Q/C from engineering

  17. Safety Systems Organizational changes since the last LCLS ARR • PPS and BCS Systems combined into a single Section under new management (E. Carrone) • Full-time QC Group Leader (M. Saleski) • Manages the Review & change order Processes • Full-time Documentation Manager (S. Starner). • Documentation compliant with DOE Order 414.1C and ISO 9001 • New “Backup” PPS Engineer undergoing training to provide additional PPS System Expertise. • New Test Leaders have been trained during past IATs. • A training tracking procedure (and a registry) is in place.

  18. Documentation Control • A single on-line repository is available for all released documents. • Formal Documentation Control is in place. • Measures taken to regulate the Preparation, Change, Withdrawal, Review, Approval, Release, Distribution, Access, Availability, Storage, Disposal of documents. • Document management Plan, Document Change Control Procedure, design Review Plan, Drawing Management Procedure, Engineering Change Order Procedure.

  19. Configuration Management Documentation • Document Management Plan • Document Change Control Procedure • Document Change Order • Design Review Plan • Software Configuration Management • Engineering Change Order Procedure • Engineering Change Order • Drawing Management Procedure

  20. Relevant SOs informed of projects and intended review scope early in process. Process is tracked with ECO. ECO close-out is contingent on readiness of ‘as-built’ drawings, testing procedures, etc. Internal Design Review Process

  21. PPS Software is stored in a dedicated PPS repository. Released software always has “N.0.0” version tag. Documented software bench testing is performed prior to deployment. Software Configuration Management Procedure

  22. Software Configuration Management Support • Software versions are checked during annual certification. • Written procedures exist for extracting PPS code from CVS and for uploading it to PLCs. • A documented training program tracks personnel PLC qualifications in the Section.

  23. Conclusions Controls Department is prepared and ready to support and to maintain the LCLS facility
