Summary

2. New responsibilities in Controls
Enzo Carrone, the new deputy in Controls Department, is responsible for LCLS control system
Ernest Williams is now the manager of the software engineering & EPICS engineering in Controls

3. Controls Status since the last review
The Linac and BC2 Controls installation went very well
The system was delivered in December 2007, within a week of the original schedule

4. Linac & BC2 Controls was ready in December as scheduled VS the schedule date of 12/3/2007

5. Summary of Controls Sub-Systems installed for Linac and BC2 Commissioning
Cable Plant
Networking
Magnet power supply
Vacuum Controls
LLRF
Timing system
Laser control upgrade
OTR/YAG imaging
BPM
Wire Scanners
Faraday Cup
Cerenkov monitor
Moveable collimator
BC2 beamline control
Bunch length monitor
MPS
BCS
Configuration software
MATLAB feedback system
Bunch length measurement

6. Linac & BC2 Controls in use by physicists & Operations

7. A new Feedback framework has been commissioned and is in operation
Longitudinal Feedback worked successfully. Currently implemented as 3 different feedbacks
DL1 Energy
DL2 & BC2 Energies
DL1, BC2 Energies + BC2 Bunch length
Feedback framework allowed significant configurability during commissioning.

8. Upgraded the Controls for the injector laser

11. Remaining Controls installation benefits greatly from the injector, linac & BC2 experience
LTU Controls is similar in scope to Linac & BC2
We are past the engineering learning curve with very little development remaining
Almost all procurement is complete including 100% of cable plant
All IOCs and VME crates are on hand
The order for over 95% of all required control modules (PLC, ADC, motion control, etc.) has been placed
Some I&C rack delivery is being delayed, no impact on installation
Racks are currently being loaded & tested in high bay area

12. Rack Assembly Area (B024 )‏
B913 & B921 PS racks
B911 & B912 PS racks

13. INSTALLATION SCHEDULE

14. PPS cable plant installation is in progress

15. The readiness status of all systems including racks are reviewed weekly

16. Equipment Status / Rack Readiness – B921

17. Schedule – B913

18. Safety Systems BCS MPS PPS Mature design Project is on schedule
Concurrently developing new LCLS MPS
Response time of less than one pulse at 120 Hz
New hardware extended 1.2 km past current MPS
Non-CAMAC
Ready for photon section
PPS
The system design is based on the extension of the injector PLC-based architecture
Need to now address the BSY area

19. Undulator Control System developed in collaboration with ANL
Undulator motion control system
UCMI Design complete - contract awarded
UMPI Design is complete
All parts including VME hardware are on-site
Assembly started May 12. Expect to take ~2 weeks
Layout of rack is complete; 33 loaded Mini-racks will be shipped to SLAC mid June
UCM Software testing and debugging complete.
Version 1.0 released in April

20. Undulator Motion Control Software delivered by ANL and is being checked out

21. Undulator Control System is on schedule for field installation
Magnet power supplies: in very good shape
Loaded racks are being tested in B024/B15
There is a detailed schedule covering bench testing, through field installation
Software design is mature, requires little if any changes
RF BPMs – production proceeding well
Receivers will be shipped to SLAC June-July
Timing, Vacuum, Networks are all on schedule
WPM (6 Mini-racks), HLS: 1 Dbl rack in B913 & 4 CISCO enclosures will be interfaced to the control system

22. Conclusions
The linac & BC2 control system is online & operational
We are on schedule for the installation and completion of electron control system
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
