Injector Control System Installation
Response to Previous Concerns
Status update
Summary

2. Controls Status Following the Last Review
Concerns were expressed at the last review regarding the availability of the control system for injector commissioning in January
Some specific issues…
Lagging procurement, indicating slow progress in a number of areas
Timely availability of high level applications software
Lack of sufficient technical expertise in a number of areas, particularly in electronics hardware engineering
Insufficient involvement of experienced SLAC engineering and technical staff to complete the product lifecycle from production to installation

3. The focus in the past eight months has been on timely installation of the injector Controls
Complete the design of critical systems and follow through with system production
Accelerate procurement activities to ensure availability for installation
Align cable plant design and procurement with the project-wide installation schedule
Collaborate with the physicists to ensure the availability of required software tools for machine commissioning
Better use of Lab resources through integration with other departments and groups

4. Integration of LCLS Controls with other Departments & Groups at SLAC
Following the last review, prepared a list of the required expertise to follow through with the Controls plans
Identified individuals at SLAC who would be invaluable to the LCLS controls effort
Obtained support and approval from Department heads and the directorate for the integration of the individuals with the project
Formed “Engineering Teams” to address integration issues

5. LCLS Engineering Teams
The goals for the Engineering Teams are:
Multi-disciplinary teams to manage the full product lifecycle from specification and design to engineering development, production, installation and commissioning
To ensure communication among all disciplines, and that all interface issues are addressed
Each team has representatives from Controls, PCD, Mechanical Systems, Physics, CF, etc.
Most recently, full integration of the LCLS & SLAC controls effort into one Controls Department

19. 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 1 Hz, and the camera is synced to 120Hz.
The prototype of the first loop has been tested for several months and works well.

31. High Level Applications – Change in Direction
Fariley
Zelazny
Chevtsov
The original plan for high level applications called for making use of both the XAL and SLC applications suites
The applications group has been temporarily re-assigned to other tasks
Supporting Timing System, Feedback, Magnet control, etc.
The new plan for Injector commissioning calls for…
Making heavy use of MATLAB for application development
Providing access to most control subsystems from MATLAB
Enlisting the support of accelerator physicists in developing some of the required applications
The Applications Group to provide the MATLAB interface to the accelerator data and the supporting infrastructure
To migrate the applications to the XAL environment at a later date

32. High Level Applications

38. Conclusions
Great progress has been made in the past eight months towards readiness for injector installation
We have had to make a few interim adjustments to meet the commissioning deadlines
The collaboration with other departments at SLAC has proven very productive
While commissioning the injector, we need to be aware of the installation schedule for the rest of the machine including the experimental areas
Through collaboration with the physics group we are ensuring the availability of required applications software for injector commissioning.
