John N. Galayda LCLS Facility Advisory Committee 7 April 2005 Ultrafast Science and LCLS Experiments – 120 Attendees, all prospective users Organizers: Jerry Hastings and Keith Hodgson Monday-Tuesday, October For program information see: A Workshop in Ultrafast Science and LCLS Experiments at SSRL will be organized on October 25-26, There will also be a pre-registration reception on Sunday evening, October 24th from 5-7 pm. The tentative schedule for the workshop is a joint session on Monday morning, October 25th. On Monday afternoon and Tuesday morning, there will be breakout sessions for each of the five thrust areas of the LCLS: (1)Atomic, molecular and optical physics (2)High energy density states of matter (3)Optical pump-x-ray probe studies in chemistry, biology and materials science (4) Diffraction imaging of single objects approaching atomic scale resolution and (5) Coherent x-ray scattering for the study of dynamics (X-ray photon correlation spectroscopy) The workshop will end with a joint session on Tuesday afternoon, October 26th. The workshop and breakout sessions will focus on the scientific goals and technical needs of the LCLS experimental end-stations, as well as experimental specifications. This workshop provides an opportunity to all users, including potential future users to participate in building ultrafast science at LCLS by providing input and sharing their scientific ideas. For atomic, molecular and optical physics breakout session at the meeting please contact Lou DiMauro Phil Bucksbaum Nora Berrah Jerry Hastings For the other breakout thrust areas please contact John Arthur

John N. Galayda LCLS Facility Advisory Committee 7 April 2005 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
John N. Galayda LCLS Facility Advisory Committee 7 April 2005 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".
John N. Galayda LCLS Facility Advisory Committee 7 April 2005 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
John N. Galayda LCLS Facility Advisory Committee 7 April 2005 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
John N. Galayda LCLS Facility Advisory Committee 7 April 2005 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.
John N. Galayda LCLS Facility Advisory Committee 7 April 2005 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
John N. Galayda LCLS Facility Advisory Committee 7 April 2005 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
