9. Hamid Shoaee LCLS Facility Advisory Committee hamid@slac.stanford.edu 20 April 2006 9 There has been a re-prioritization of control software development to ensure control system availability for injector commissioning The applications group has been temporarily re-assigned to other tasks Supporting Timing System, Fast 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 The critical Bunch Length Measurement application will be first prototyped it in MATLAB by the applications group The physics group will develop prototype Emittance / Energy spread applications in MATLAB

10. Hamid Shoaee LCLS Facility Advisory Committee hamid@slac.stanford.edu 20 April 2006 10 FAC Response 1 – Database Due to the late hire of an experienced database expert, the central RDB is behind where one would hope for at this point in the project, and the controls team is currently planning to use the RDB for the online model, but not for other control system configuration needs. The online model will be needed for both the new XAL based applications and the old SLC applications, and it is important that both models are derived from the same source (RDB) rather than attempting to make updates in two or more places that will quickly become unsynchronized. It does appear that there are plans in place to store hardware configuration information in the RDB, but there is not yet a plan in place for how the database will be populated and maintained, or used during the construction and operations. The use of an RDB received a late start in the project and as a result it has not played a central role in the control system. Our plans still include making extensive use of an RDB as soon as we have addressed the injector commissioning schedule

11. Hamid Shoaee LCLS Facility Advisory Committee hamid@slac.stanford.edu 20 April 2006 11 FAC Response 2 – SLC Integration and High Level Applications With the recent evaluation of the requirements for High Level Applications, plans to use a combination of existing SLC applications and newer XAL based applications, it is apparent there will need to be the ability to send commands (such as writing set points) from XAL applications and/or EPICS IOCs to hardware controlled on the SLC side. This was not previously planned and will need to be addressed soon. We are also concerned about plans to share the PEP proxy server during LCLS testing while PEP continues to run. Such tests could introduce loads or other problems that would impact PEP operations and an isolated proxy server should be provided if possible This will be addressed when we resume the development of XAL high level applications. Injector commissioning will make use of the existing SLC applications as well as MATLAB based tools.

12. Hamid Shoaee LCLS Facility Advisory Committee hamid@slac.stanford.edu 20 April 2006 12 FAC Response 3 – PPS The PPS system plan calls for a PLC based implementation. Since this implementation choice is new for PPS systems at SLAC, an internal review is required, and tentatively scheduled for November 2005. It is important that this review take place on schedule so work on the PPS system can proceed on schedule. The internal review of the PLC-based PPS has taken place and the committee is nearing approval of the implementation. The project has also been reviewed by experts from other labs such as Jlab and APS. The design of the PPS is more than 90% complete and the Final Design Review is scheduled for next week. There will be a detailed presentation on this subject during the Controls Breakout session.

13. Hamid Shoaee LCLS Facility Advisory Committee hamid@slac.stanford.edu 20 April 2006 13 FAC Response 4 – MPS (Himel wins 5 ¢) Work on the MPS system was recently started. This is a late start, and we are still concerned that it is a complex enough system that will be difficult to complete on time. We suggest that the functional requirements of the SLC “new MPS system” and the SNS MPS system be examined to help you determine the requirements for the LCLS MPS system. Also, to encourage prompt completion of the project, Himel made a high stakes bet (5 cents) with Dalesio. Dalesio wins if the MPS system is operational at the end of the November 2006 shut-down. To address the late start in the MPS system for the injector commissioning, a decision has been made to extend the existing Linac MPS to the injector and BC1 region as an interim solution. There is a detailed schedule for this activity and the plan is on course.

14. Hamid Shoaee LCLS Facility Advisory Committee hamid@slac.stanford.edu 20 April 2006 14 FAC Response 5 – Management Organizationally, the distributed nature of Controls throughout the WBS structure still makes things a bit confusing. It would be helpful if the Controls manager was provided the same type of reports for all controls activities, as are available for higher level WBS elements. The controls activities appear to be well planned and running smoothly under the leadership of Bob Dalesio, however, it has long been recognized that a “local” and more permanent group leader is necessary. With this hire now imminent, it is important to plan for a smooth transition to ensure there is no disruption to the current activities which need to proceed on schedule to meet project milestones. We recommend a period of overlap for Bob and the new group leader to help keep progress on track. The new group management is in place and there has been a smooth hand off in the process

15. Hamid Shoaee LCLS Facility Advisory Committee hamid@slac.stanford.edu 20 April 2006 15 FAC Response 6 – Process It appears that controls work is now being reviewed (internally in most cases) at appropriate stages, however, care should be taken to ensure these reviews are documented for future reference. Since the last FAC review there has been a concerted effort to produce the required set of documents for each project as defined by the LCLS project office. These include PRDs, ESDs, ICDs, etc. We are also proceeding with formal reviews of each project including magnet power supplies, vacuum system, cable plant, PPS, etc.

16. Hamid Shoaee LCLS Facility Advisory Committee hamid@slac.stanford.edu 20 April 2006 16 FAC Responses 7 – BPMs Schedule is tight for BPM readout electronics. A first version of the Analog Front End (AFE) for the BPM system has been produced and its performance (resolution, linearity, etc.) has been verified on bench top and with actual beam. A revision to this board is currently under design.

17. Hamid Shoaee LCLS Facility Advisory Committee hamid@slac.stanford.edu 20 April 2006 17 FAC Response 8 – Security For the next FAC meeting, we would like to see the overall network and cyber security plans. There is a separate presentation on this topic during the Controls Breakout session.

23. Hamid Shoaee LCLS Facility Advisory Committee hamid@slac.stanford.edu 20 April 2006 23 Conclusions An excellent team is in place There is very productive involvement by other departments at SLAC The WBS is being changed to reflect the current approach to development and installation By the end of this exercise we should have a better handle on the control system cost We are on course for control system installation for the injector. The schedule is very tight with very little float We need to resume the development of long term high level applications, feedback systems and the use of RDB
