With a few exceptions the procurement of control components has been completedWhile 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.

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

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

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

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.

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

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.

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.
The prototype of the first loop has been tested for several months and works well.

ConclusionsGreat progress has been made in the past six months towards readiness for injector installationWhile the majority of Controls subsystems will be installed on time, a few will be just in time deliveryAn ETC exercise has identified and fixed a number shortcomings in the baseline budgetThe collaboration with other departments at SLAC has proven very productiveWhile commissioning the injector, we need to be aware of the installation schedule for the rest of the machine including the experimental areasThrough collaboration with the physics group are ensuring the availability of required applications software for injector commissioning.
