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

24
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".

25
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

26
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

27
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.

28
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

29
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). ---

Where Are We Now

• About to transit from administrative/design
  activities to construction activities
• Training profiles must change accordingly
• About to heavily exercise LCLS-SLAC synapses
• Citizens committees
• Matrix support from Technical Division, CEF
• SLAC oversight
• Oversight of LCLS activities at ANL, LLNL

35
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

36
