The main focus in the past six months has been the installation and commissioning of the injector Controls
Installation of the cable plant including trays, long haul DC and I&C cables, terminations, etc.
Phase 1 (Apr. ’06 thru Jun. ’06)Phase II (Aug. ’06 thru Dec. ’06, including Christmas holidays)Final terminations were occasionally delayed pending mechanical installations
Installation of the electronics racks, loading of crates, electronics chassis, modules, and intra-rack wiring
Installation of the Controls software on the front-end computers (IOC) and production servers

All LCLS Safety Systems Are Operational
Laser Safety System (LSS)Was needed early to allow laser commissioning
PPSPassed many reviews by internal and external reviewers, citizens committeesThe FIRST SLAC programmable PPS is online and operational
BCSPrevents radiation from ‘escaping’ the shielding enclosureDirect measurements of radiation or beam lossProtection of safety-critical collimators and stoppers The need for BCS was identified late, and the system had an aggressive schedule, but was completed and certified in time for ARR approval

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 tubeThe 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.

Linac & BC2 Controls Installation (Fall ‘07)
BC2 installation, similar scope to BC1Very little engineering developmentThe biggest challenge is meeting the scheduleThe scope includes
Extending the new timing systemSafety systems (MPS, BCS)Adding new magnets including pulsed horizontal pulsed horizontal dipole magnetdipole magnetAdding BPM, x-collimator, OTR screenBPM electronics upgraded (resolution improved)BPM electronics upgraded (resolution improved)

X-Ray End Station DAQ & Controls
Developed a conceptual design for end station data acquisition and controlHeld a Conceptual Design ReviewDeveloped 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 hourThe 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.

Conclusions
The injector control system is online & operationalIt has taken heroic effort by Controls group to meet the commissioning deadlineThe plans are in place for linac & BC2 installationWe have developed a detailed plan for the undulator control in collaboration with ANLA conceptual design is in place for X-ray End Station data acquisition and controlThe major risk for the above items is schedule rather than technical complexity
