19. Hamid Shoaee Control System Installation Readinesshamid@slac.stanford.edu 3/16/2007 19 LCLS Controls systems For each system… Technical leads have developed a schedule covering all phases leading to installation and commissioning The schedules include development of appropriate field documents (EI, WD), rack profile/cable plant design, procurement, installation and system checkout Continue Interfacing with Mario Ortega, Bob Fuller, Mike DiSalvo to coordinate procurement and installation We will be reviewing each schedule to identify bottlenecks, dependencies on other systems, resource availability

20. Hamid Shoaee Control System Installation Readinesshamid@slac.stanford.edu 3/16/2007 20 Safety Systems for BC2,L2,L3 PPS The Linac PPS does not require modification to run LCLS beam to SL-2. There is an AIP project to convert the Linac and BSY to the LCLS PLC- based system in 2008 MPS We will use the current (1553-based) MPS for BC2. Two new ion chambers will be required The system will include 10 LDIM inputs OTR21 (2ea) OTR22 (2ea) OTR_CAV (2ea) BC2 Mover (2ea) CE21 (2ea) We will need to commission AP25 (currently installed but powered down) to accommodate a new PICP module and an LDIM (already installed).

35. Networks will be ready early in October to allow Controls checkout

36. Hamid Shoaee Control System Installation Readinesshamid@slac.stanford.edu 3/16/2007 36 Timing System The scope is to deliver triggers and timestamp data to all subsystems requiring such. The system can be split into two parts 1.Long-haul distribution of triggers from the EVG to EVRs in Linac and beyond 2.Short-haul back end consisting of the HW & SW to receive the EVG timing signal and generate triggers. This is well-understood and defined. Part 1 requires some engineering development as the event system can only have a maximum link length of 300 meters. We can daisy-chain, but only for 3 hops before exceeding the jitter budget. We need a better solution This is a tractable item and should not have a high level of risk. Another item of concern with the long-haul distribution is timing phase error due to temperature drift – a mechanism is needed to correct for this. This will need some R&D and we need to decide based on short- versus long-term requirements if users can live with this for now. We have to anyway since time is short We have a procurement for the "back end" of the timing system consisting of all the HW (fan-outs, EVRs, crates, cables) to deliver triggers to the end subsystem. The long haul procurement list is pending a design decision

37. Timing System Schedule

38. Hamid Shoaee Control System Installation Readinesshamid@slac.stanford.edu 3/16/2007 38 Beam Instrumentation & Diagnostics Profile Monitors There are 3 OTRs in the LINAC: OTR21, OTR22, OTR_TCAV – These use BC1 designs and electronics Design in April, procurement in May, system test July ~ August. Toroids There are two toroids in linac: IMBC2I and IMBC2O We need to re-spin the data acquisition board for small revisions to the artwork Electronics will be ready in August for system testing Bunch Length Monitor BL21 and BL22, similar to BL11 and BL12 in BC1 Procurement in April and test in May ~ June. Dumps and Stoppers SL2 might need some new data monitoring.

39. Hamid Shoaee Control System Installation Readinesshamid@slac.stanford.edu 3/16/2007 39 Beam Position Monitors The linac BPMs have to be upgraded for better resolution for undulator commissioning in May-June ‘08 Do we need to upgrade for the BC2,L2,L3 commissioning? Do the existing BPM electronics work at 200 pC? Do they trigger reliably at low charge? What resolution do they provide? Test next week with A-Line beam If we need the linac BPM upgrade Install 20 racks Design and install cable plant for 79 BPMs Re-spin BPM analog front-end design Fabricate and test 120 BPM chassis Install 79 BPM chassis If we can defer the upgrade We still have to install the cable plant for all of the linac BPMs in this down time Of the 17 BPMs in switchyard we will connect to only 2 And one BPM in BC2

42. Hamid Shoaee Control System Installation Readinesshamid@slac.stanford.edu 3/16/2007 42 Testing & Checkout Strategies For each subsystem, we will use test stands to verify the complete system Test stands currently in place include: Timing Vacuum Magnet power supplies Motion control – wire scanners, collimator, etc. Rack loading & testing Need to accomplish as much as possible in B024 prior to Sept. transport to field site. In-field loading (Davis-Bacon) and intra-rack cabling is less efficient.

44. Hamid Shoaee Control System Installation Readinesshamid@slac.stanford.edu 3/16/2007 44 Issues & Concerns Schedule & Resources Schedule is very tight, just fits in down time Controls is the systems “integrator” – delays in other systems directly impact our installation Cable Plant Installation Coordination of activities with other installation groups is very important and could jeopardize schedule Linac BPM upgrade could be an added challenge System Functionality Timing System – small concern BPM, Toroid – need verification of design

45. Hamid Shoaee Control System Installation Readinesshamid@slac.stanford.edu 3/16/2007 45 Summary Controls in general is in good shape for 2007 installation No major design or production issues dominate the plan The schedule is challenging with little float While a large number of sub-systems will be installed on time, some will need attention to stay on schedule
