18. How Will We Get There • Write Safety Assessment Document • Identify certain generic design features to control hazards • Busbar covers? “Power ON” warning lights? • Pinch hazard covers? • Local crash buttons for motors? • Enclosed laser paths? laser interlocks? • Confirm it is all there in the Readiness Review

20. How We Will Get There • Schedule our safety design reviews like other project activities – by subsystem • Flowcharts for Safety Approval processes with branches to address, e.g. • Design • Review • Authorization • Work planning/execution • JHAM • AHA • Electrical Work • Hoisting • Excavation • Work Authorization

21. A Concern- Can We Live With This? A lot of people are waiting to “hear” from us on this

23. FFTB/SPPS • Schedule • Must preserve funds for FY boundary BUT • Acceleration of 2006 procurements considered • Conventional construction – SPPS/FFTB schedule • LCLS schedule shows May 2006 Shutdown • Some evidence that delay past March 2006 will delay LCLS commissioning start- • Linac Complete by end of 2006-2007 shutdown • Startup planning should exploit this!

24. What’s Next • Review Calendar • FAC 7-8 April 2005 • SAC 5-6 May 2005 • Lehman 10-12 May 2005

25. X-Ray Subgroup- Paul Fuoss presenting • Issues: • Details of designs are sparse, User workshops should be aimed at collecting more detail. • There is not enough effort going into the shot-by-shot beam diagnostics (?) • There is not enough effort going into optics stability • Consider making the center hutch in the far hall longer • Recommendations • Concentrate on LCLS-specific problems such as shot-by-shot diagnostics, data flow, feedback control, preservation and measurement of coherence • The detector advisory committee should coordinate the effort of LCLS and MIE • Identification and communication of critical issues to LCLS experimenters should be a priority • Do not fund detector efforts unless resources are sufficient to produce a useful end result

26. Controls • Global standards are required - push for this (vacuum? where is the interface?) • You desperately need a central database for all project data (not just controls) • SLC-aware IOC good progress prototyping, still lack functional requirements and top level design decisions on Applications and which should be EPICs vs SLC. • X-ray beam line controls requirements must be defined • BPMs - are electrons and positrons on a single pulse still needed? Is it OK to simply keep the "old" original electronics in place and disconnected, so the new electronics are limited to LCLS requirements? • BPM location and anchoring must be decided • Undulator BPM performance requirements should be articulated including max working range • The engineering process seems to be proceeding without explicit requirements and reviews. An example of this is the PNET module • Where is global controls on the org chart? • Can we get x-band klystrons and waveguides from the NLCTA? • Injector laser controls interface needs close communication between vendor, controls group and laser experts/operators • Follow new code requirements for low-smoke fireproof cables • It is unclear how to design feedback to control X-band phase- explore "dithering".

27. Electron Systems • Do gun tests as early as possible, at vendor maybe consider creation of a gun test facility • Order 2 guns • They recommend continued testing of laser pulse shaping at DUVFEL • Consider doing electron beam tests at DUVFEL • Consider collaboration with LLNL on gun laser development • Recommend a hot spare laser • Recommend the formation of a laser group • Consider doing tests of "lock-in" detection of low gain at DUVFEL • Consider x-band waveform modulation as the input modulation for lock-in detection • Show analysis and simulations of collimator performance at the next review, including shower computations • Continue work on ESASE • Recommend x-y scanners for wire monitor, rather than diagonal • Consider the design of a feedback loop that adjusts the laser based on electron beam measurements • Consider options for the ULTIMATE LCLS Master Oscillator • Continue tests of THz measurement techniques at SPPS (WHEN?) • Consider schemes to modulate X-band phase for optimal set-up • Place appropriate emphasis on challenging phase/amplitude control of X-band system • By 1/2005, force a decision on undulator design changes for AC wake field

28. Undulator Systems • Cradle system needs attention • Trade-offs must be considered to decide whether longer girders can improve tolerance to ground motion • They recommend that, if the gap/period is changed, a new prototype is not necessary • Consider feed-forward from temperature measurement to undulator horizontal position to control K • Decision has been made to NOT to hire a general contractor responsible for delivering complete undulators. The consequences of this decision (plans for control of final assembly) should be presented

29. Conventional Facilities • Prepare a prediction of floor performance in terms of settlement and vibration, based on SLAC experience, calculation, etc. that covers "DC-to_daylight" bandwidth • Give serious consideration to "active" alignment techniques to compensate for performance limitations of floor and supports • Give further consideration to where cut/cover is better than tunneling • Consider heating the tunnel walls • Report the earthquake design criteria for LCLS construction • CLO- 300 people in 90,000 square feet seems tight- revisit space allocation • Committee is skeptical of 27 month construction schedule • We need a construction procurement expert • We need a construction safety expert • W need a construction QA function/program • We need a review by a fire safety engineer • Confirm that the standards chosen (UBC1997 was an example quoted at the review) are the latest, and that no changes in requirements and standards are imminent. (?) • Consider an excavated tunnel cross-section that is not circular • Go through a cost-optimization exercise. it may be possible to save money on construction cost • Consider having your procurement group set up bulk purchasing agreements for commodities.

30. Robinson Summation • Risk registry should show AC conductivity • Prepare a tunnel/undulator stability/error budget!! • The Project mgmt has not yet demonstrated global systems integration • Go through a value engineering cycle • Improve integration between conventional facilities and laser systems

31. PIXEL Initiative • Experiment Stations (instruments?) for LCLS • CD-0 Draft under review • Warm Dense Matter looking for funding outside BES

32. End of Presentation

33. Start of LCLS Project

35. I am happy to announce that Paul Emma has agreed to take over leadership of the LCLS accelerator system physicists' group. Paul's ability, cooperative spirit and dedication have earned him the respect of his peers and the LCLS WBS managers alike. I should add my expression of gratitude to the system physicist team for their advice to me and their efforts to make the LCLS a success. I ask that you all give your support to Paul and the Accelerator Systems Physicist team as we turn the LCLS from a dream, nearly 14 years in the making, into a groundbreaking scientific facility and a running facility. The photon systems physicists, John Arthur for X-Ray Transport/Optics/Diagnostics and Jerry Hastings for X-Ray End Station Systems, will continue to report to me in this capacity at present, in addition to their responsibilities to SSRL and the PIXEL initiative (which will complete the suite of experiment stations for the LCLS). --- John Galayda
