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

Main Control Center is in full operation
All LCLS Safety Systems Are Operational
Laser Safety System (LSS)
Was needed early to allow laser commissioning
PPS
Passed many reviews by internal and external reviewers, citizens
committees
The FIRST SLAC programmable PPS is online and operational
BCS
Prevents radiation from ‘escaping’ the shielding enclosure
Direct measurements of radiation or beam loss
Protection 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

Injection Laser Control System
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.

Linac & BC2 Controls Installation (Fall ‘07)
BC2 installation, similar scope to BC1
Very little engineering development
The biggest challenge is meeting the
schedule
The scope includes
Extending the new timing system
Safety systems (MPS, BCS)
Adding new magnets including pulsed horizontal
dipole magnet
Adding BPM, x-collimator, OTR screen
BPM electronics upgraded (resolution improved)

X-Ray End Station DAQ & Controls
(Presentation at controls breakout)
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.

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
