15. Hamid Shoaee LCLS Facility Advisory Committee hamid@slac.stanford.edu October 2006 15 Installation details will be presented in the breakout session With a few exceptions the procurement of control components has been completed While the majority of subsystems will be installed on time, a few will be just in time delivery, including BPMs and Toroids electronics. Systems are typically checked out on test stands, and field installation will be done by Davis-Bacon contractors.

19. Hamid Shoaee LCLS Facility Advisory Committee hamid@slac.stanford.edu October 2006 19 FAC Response 1 – MPS The controls group made the wise decision to extend the 1553 MPS system for the injector turn-on and will later continue development of the newer MPS system (which is needed to respond in 1 pulse rather than the 3 pulse response time of the 1553 MPS system). An update on MPS progress should be presented at the next FAC meeting. In addition to implementing the 1553 system, further work should be done on the new system. There will be a presentation on the MPS in the breakout session. Work has been done on the design of the linac MPS and a design review will be held in November

20. Hamid Shoaee LCLS Facility Advisory Committee hamid@slac.stanford.edu October 2006 20 FAC Response 2 – BPM They still have a tight schedule. There has been progress since the last review, but no decision has been taken on which digitizer to use yet. This decision should be taken very soon. The schedule is still very tight. However we have selected a digitizer and the details will be presented at the breakout session

21. Hamid Shoaee LCLS Facility Advisory Committee hamid@slac.stanford.edu October 2006 21 FAC Response 3 – Cost, Schedule, cable plant concerns Management has changed. [Hamid] has made some changes and does think they can support an on time injector commissioning with some temporary solutions. We agree with the latter statement and believe the schedule will be very tight. Particular attention is needed for the cables in the linac which must be installed in the coming shutdown. We support Hamid’s plan to rework the schedule and cost estimates. Linac Cable plant installation is proceeding well and will be completed during the shutdown. There has been a bottom up cost estimate of the control system

22. Hamid Shoaee LCLS Facility Advisory Committee hamid@slac.stanford.edu October 2006 22 FAC Response 4 – Use of commercial solutions It seems like now there is less emphasis on using COTS solutions. Increase that emphasis please. For example the plan has been to use a commercial card for the timing system, but now they are thinking of getting rights to the design and modifying it to remove unused functionality and reduce cost. We highly doubt this would be worth the engineering effort. All timing system electronics have been procured from the manufacturer. There are no plans to produce them locally. With a few exceptions, most of the controls electronics consist of commercial boards: exceptions include BPM & Toroid AFE, LLRF.

23. Hamid Shoaee LCLS Facility Advisory Committee hamid@slac.stanford.edu October 2006 23 FAC Response 5 – Embedded IOC Different groups may be using different embedded IOCs. See if they can be standardized. Don’t do this if it is so late in the development cycle that the change would be highly disruptive. A single embedded IOC board is being used on a number of systems including BPM, Toroid, BLM, LLRF

24. Hamid Shoaee LCLS Facility Advisory Committee hamid@slac.stanford.edu October 2006 24 FAC Response 6 – Management Controls would benefit from a full time deputy and designated technical leads for each technical area. The latter would be people who spend 25% of their time on management and do technical work the rest of the time. The recently revised controls budget includes a deputy position which will be posted shortly.

25. Hamid Shoaee LCLS Facility Advisory Committee hamid@slac.stanford.edu October 2006 25 Update April 2006 – October 2006 (1) Long Haul cable plant design is complete and reviewed.

29. Hamid Shoaee LCLS Facility Advisory Committee hamid@slac.stanford.edu October 2006 29 The injector laser stabilization system includes two feedback loops The first loop includes two mirrors, each with two actuators and one camera. It stabilizes laser traveling through a 10-meter tube The second loop includes one mirror with two actuators and adjusts the laser position on the cathode. The IOC reads the image from camera, calculates the laser’s position error and applies a correction to the actuators. The loop operates @ 1 Hz, and the camera is synced to 120Hz. The prototype of the first loop has been tested for several months and works well. Injection Laser Control System
