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

  11. 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, communicate, 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.

  14. LCLS Software Tasks – Development • SLC-aware IOC • Drivers for all new hardware • Machine Protection / Mitigation • Master pattern generator • Fast Feedback Communication • High Level Applications • Correlation Plots • Fast Feedback Loops • Emittance reconstruction from wire scans and profile monitors • Profile monitor image analysis for slice emittance with the transverse cavity • Beam Steering and online orbit modeling • Beam Steering “scans” to emittance reconstruction from wire scans and profile monitors

  15. LCLS Software Tasks – Control Programmer • 1 RF Control • 2 Diagnostics • 2.1 Toroids & Faraday Cups • 2.2 Beam Stops • 2.3 Profile Monitors & Video Devices • 2.4 Wire Scanners • 2.5 Bunch Length Monitors & E/O Diagnostics • 2.6 Beam Position Monitors • 2.7 Collimators • 2.8 All other stops • 3 Gun Laser and Drive Control • 4 Vacuum • 5 Magnet Power Supply Control IOC and software • 6 Beam Containment / Personnel Protection / Machine Protection

  16. Next 12 months • Acquire team: 8 project engineers, 1 low level programmer, and 3 board designers – or contract out or steal designs • Start PNet, Timing, LLRF, and BPM design efforts • Start the SLC-Aware IOC development • Put together detailed designs per subsystem and have them reviewed – revamp costs. • Develop prototype for 120 Hz Fast Feedback • Develop prototype for video diagnostics • Develop prototype for position controllers

  17. Conclusions • We need to acquire some key resources to get the critical designs well in hand before they are needed • Our key risk is in the design of an SLC-aware IOC and SLC to EPICS timing that will allow us to intermix the SLC and EPICS front-ends. It is also provides a valuable upgrade path for the SLC Linac. • We need to make Interface Control Documents for each control subsystem.
