  1. Controls OverviewApril, 2005 • Outline • Goals • Status update • Resources • Design Slides for Global Systems • Task descriptions • Next 12 months • Conclusions • Note: As this is being recorded – please add ” it is my impression” and “we expect “ wherever appropriate.

  2. LCLS Control System Goals • Provide a fully integrated control system to support the construction, test, installation, integration, operation and automation of the LCLS Accelerator • Standardize on all devices and components across all subsystems. • Identify all data either by pulse id, beam pulse related time stamp, or 500 msec rough time stamp. • Full integration with the SLC – timing, use of LCLS data in SLC high level applications, and use of SLC data in LCLS • Work with ESD to provide an upgrade path for the SLC

  3. Update May 2004 – April 2005 • 3 month continuing resolution • Acquire personnel • 8 project engineers – Koturri, Lucchini, Allison, Straumann, Murray, Fairley, Rogind, (offers being made to junior engineer, jobs open for junior proj. eng) • 1 low level programmer (offer being made to junior engineer) • 3 board designers – (support from ESD, evaluating existing designs, interviewing • Steve Lewis on controls at LLNL • Detailed designs to be completed Sept. with costs revamped • Facility Controls, XRay Transport are integrated into control design (details remain) • Prototypes in test: • PNet – hardware design complete, driver functional, tests needed • Timing – hardware from SLS being put into test • Power Supply – hardware from SLS in test for stability and precision • Video – cameras in test • Design efforts ready for prototyping: LLRFand BPM • SLC-Aware IOC is 70% complete. • Prototypes needed for 120 Hz fast feedback and position controllers.

All EPICS high level applications are channel access clients that may or may not have a server.

  11. Fast Feedback Fast feedback is required to run at 120 Hz Values will be transmitted from RF and selected diagnostics to Power Supply and RF IOCs The communication needs to be reliable, verifiable, and have a well thought out degradation The entire time budget to read, transmit, commute, control, and settle is 8.3 msec First estimates are that the control system can use 2 msecs to transmit and receive the data Can this be done over a common Ethernet with adequate bandwidth – or is a dedicated one needed?

  12. Machine Protection Machine protection is used here to define faults requiring global mitigation Response time is under 8 msec There are two mitigation devices: Single Beam Dumper - which prohibits the beam from entering the undulator Drive Laser Off – which prohibits beam from entering the cavity Action must also be taken to reduce the repetition rate of the beam This new design is required to interrupt the beam before the next beam pulse.

  18. Conclusions • Control engineers are in place for all major subsystems. • The WBS has been reorganized to move all of the design activities into global controls under 1.1.3.5. Signature authority for all x.x.2 leve WBS is shared. • The SLC-aware IOC and SLC to EPICS timing issues are well on the way to being resolved. • Hardware components have been identified for most of the risky areas. MPS needs attention. PPS needs to complete the citizen review. • By the end of this year, hardware designs should be proven as prototypes and the schedule and budget revamped to reflect the final design desicisions.
