5. LCLS Controls Group Staffing
The control system development is performed by a matrixed group of about 50 engineers and technicians organized in two dozen teams
Each team manages the full product lifecycle from specification and design to engineering, production, installation and commissioning
LCLS Controls Group is now fully integrated & matrixed within the SLAC Controls Department
To manage the proliferating use of EPICS for LCLS, we recently hired Ernest Williams from SNS

6. LCLS Controls is matrixed within the Controls Department

7. Accomplishments in the past eight months
Installation and commissioning of the Injector Control System
Completion of the design and detailed plans for 2007 linac controls installation
Coordination and re-planning of undulator control with ANL
Development of the Undulator Control Module by ANL
Development of X-Band Cavity BPM, receiver and data acquisition system by ANL and SLAC
Design of next generation applications software

8. The main focus in the past eight 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)
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

9. Main Control Center is in full operation

10. All LCLS Injector Safety Systems were Operational on Schedule
Laser Safety System (LSS)
Was needed early to allow laser commissioning
Personnel Protection System (PPS)
Passed many reviews by internal and external reviewers, citizens committees
This is the FIRST instance of a modern programmable PPS at SLAC and is fully operational
Beam Containment System (BCS)
Prevents radiation from ‘escaping’ the shielding enclosure
Protection of safety-critical collimators and stoppers
Machine Protection System (MPS)
Adding new signals and devices for LCLS
Pockels cell and MPS mechanical shutter limit laser rate on cathode

15. Injection Laser Control System
The injector laser stabilization system includes two feedback loops
Loop 1 stabilizes laser traveling through a 10-meter tube
Loop 2 adjusts the laser position on the cathode.
The digitized laser images are process by a computer which calculates position errors and applies corrections

16. A suite of Control Room Applications Software is available for physicists & operators
Configuration management (save & restore)
Alarm management
Error Logs
Data archiving
Correlations plot
Buffeted acquisition
Online model
Problem reporting and tracking
Operations and Physics electronic log books

20. Linac & BC2 Controls installation benefit greatly from BC1 experience
BC2 Controls is similar in scope to BC1
We are past the engineering learning curve
There is very little engineering development
Almost all procurement is complete
The biggest challenge is 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

21. Linac & BC2 Controls Installation Schedule Controls ready 12/3/2007

22. Plans for the Next Eight Months
Linac & BC2 Controls installation
LTU & Undulator Controls installation
Complete the designs and documentation
Process procurements including installation contract
Start the installation process
Complete the hand off of cavity BPM and undulator controls from ANL

23. Impact of Continuing Resolution
The original plans for BC2 and Linac installation called for October ’06 start of the procurement process including
Magnet power supplies
Magnet control system
I&C electronics modules
I&C racks, crates, front-end computers, etc.
Actual procurement started March ’07
We are just starting to receive and process the equipment for installation
An additional $970k of labor cost is required to meet the December controls readiness deadline

24. Conclusions The injector & BC1 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
The major risk for the above items is schedule rather than technical complexity
detailed plans are in place for the undulator control in collaboration with ANL
