  1. LCLS Control System Design, Management & OrganizationAugust 10, 2004 • Goals • Status update • Resources / Budget • Design Slides for Global Systems • Task descriptions • Next 12 months • Conclusions

  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 SLAC Control System Departments to provide an upgrade path for the SLC • Philisophy is build new designs only when we cannot find a solution commercially or at other laboratories.

Channel Access EPICS W/S Distributed Applications SLC Alpha Apps EPICS W/S Distributed Applications Xterm Xterm EPICS W/S Distributed Applications Xterm EPICS WS Distributed High Level Applications Xterm Channel Access Vacuum Ctrl EVR Power Supply Ctrl C P U E VG EVR LLRF EVR Diag C P U HPRF I/O Boards C P U C P U IOC IOC IOC A channel access server in SLC provides data from existing SLC micros to EPICS applications All IOCs have both a channel access server to allow access and a client to have access Channel access provides read/write by all clients to all data with a server. All EPICS high level applications are channel access clients that may or may not have a server.

  14. Global Communication 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?

  15. 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.

  22. Risks / Issues • Acquire team and contract out or steal designs. • Minimize the number of solutions across injector, linac, undulator, XRay beamline transport, end stations, and facility control • Provide timing, LLRF, BPMs, and power supply control hardware in FY06 • Provide SLC integration in FY07

  23. Next 12 months • Acquire team and contract out or steal designs • Prototype/test: PNet, Timing, LLRF, Power Supply Control and BPM efforts • SLC-Aware IOC Development • Prototype for video diagnostics • Prototype for position controllers • Integrate Facility Controls, XRay Transport, Experimental Hall into the control system. • Complete the detailed designs per subsystem

  24. Conclusions • Physics requirements are complete. • Engineering specifications derived from them and a technical review of the global control system has been completed. • Baseline budget meets adequately supports the design. • Our key risks are: • implementation of an SLC-aware IOC and SLC to EPICS timing that will allow us to intermix the SLC and EPICS front-ends • Hardware acquisition/development for BPMs, Timing, Power Supply Control, and LLRF in FY06 • We need to acquire some key resources to get the critical designs well in hand before they are needed.
