23. Hamid Shoaee LCLS Facility Advisory Committee hamid@slac.stanford.edu April 2007 23 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.

31. Hamid Shoaee LCLS Facility Advisory Committee hamid@slac.stanford.edu April 2007 31 X-Ray End Station DAQ & Controls Developed a conceptual design for end station data acquisition and control Held a Conceptual Design Review Developed a detailed task list and a project plan The AMOS experiment may eventually take data @120Hz producing ~700 MB/second or 2.4 TB/hour or ~58 TB/24 hour The plan is to build on previous experience. Initially use commercial digitizer and COTS CPU for spectrometer data. Use scalable technology developed for LSST for CCD data. Capitalize on years of BaBar experience with hierarchical storage and management of HEP data. ~1 TB/day raw data. ~1 TB/day derived data. ~1.5 PB total Babar data. Extend/integrate several SLAC-developed Java-based technologies for data retrieval and analysis. (Presentation at controls breakout)

35. Hamid Shoaee LCLS Facility Advisory Committee hamid@slac.stanford.edu April 2007 35 Conclusions The injector control system is online & operational It has taken heroic effort by Controls group to meet the commissioning deadline The plans are in place for linac & BC2 installation We have developed a detailed plan for the undulator control in collaboration with ANL A conceptual design is in place for X-ray End Station data acquisition and control The major risk for the above items is schedule rather than technical complexity
