Introduction
The injection laser stabilization control system includes 3 feedback loops. Each loop includes 2 mirrors. Each mirror has two actuators and one camera.The IOC should read back the image from camera, figure out laser’s position, calculate error and apply the correction to the actuators.Whole loop should be about 1 Hz. Camera should be synced to 120Hz.

StatusSpiricon Laser Beam Analyzer has arrived and has been setup
Newport XPSC8 motion controller, 4 motor drivers and 4 CMA-12CCL actuators have arrived
Integration test with vendor’s software was tried and some problems were observed but not repeatable in LLNL. Further investigation is going on.
EPICS driver and device support is available from APS. Code review has been done.
Most of code seems from Newport. The coding style is ok.“socket” is working as NODELAY with polling rather than blocked with “select”.No any connection management such as connection monitor and recovery.
1 PULNiX TM-6710CL has arrived.
1 PULNiX cam2net has arrived.Can’t get non-disclosure agreement for current protocol.GigEVison is coming.
Loaner EDT DV C-LINK PMC card arrived.Programming interface non-disclosure agreement were settled.Driver and device support development is going on.The first release is expected before the Christmas.
