Proposed draft charges for the SMTF Technical
Advisory Board are

• 1) Provide advice to the SMTF collaboration
  on technical activities towards reaching the
  goals of the SMTF, for the International Linear
  Collider, Proton Driver, Rare Isotope Accelerator
  and CW RD projects.
• 2) Give recommendations/suggestions to the
  SMTF spokespersons and Institutional Board.
• 3) Review important objectives, schedules
  and priorities of upcoming activities at SMTF.
• 4) Provide input to the definition of
  technical milestones at six month intervals.
• 5) Review SMTF progress at six month
  intervals, identifying gaps and possible problems
  in the SMTF program.
• 6) Provide input to help optimize the SMTF
  objectives.
• 7) Give summary reports to the SMTF
  collaboration.

4
How the Board will operate

• Define issue, options..
• Discussion, action items
• Aim for overall consensus, overall inclusivity
• .
• If too contentious, then vote.

5
Open List of items that need to be discussed in
the upcoming weeks/monthsFrom discussions with
Helen and Nigel

• Cryomodule related topics
• Cavity related topics
• Snowmass prep
• Industrialization
• PD topics
• CW topics
• RIA topics

6
Proposal

• Go through listAdd items to list(Resist detail
  discussion for now)Discuss one item which is
  urgent and information is ripe4th Gen Cryomodule
  (Helen)

7
Cavity related topicsfor 30 MV/m and also higher
gradient

• Continue effort to obtain three cavities from
  DESY for Jlab, FNAL and Cornell to help qualify
  facilities
• Develop a set of tools at one lab to make TESLA
  cavity
• e.g. dies and welding jigs.
• Make a 9-cell cavity out of large grain
• Make 9- cell cavity re-entrant shape
• Discuss 3.9 GHz deflecting cavity development for
  
• ILC crab cavity/CW light source
• Discuss 3.9 GHz, harmonic cavity for injector,
  possible use for ILC bunch compression,

8
4th Generation Cryomodule..

• Discuss pros and cons of different module layouts
  now under consideration for first US-ILC
  module,See Helens spreadsheets/slides
• Hold a module meeting at PAC?
• Choose, eventually
• Organize troops to make a video of DESY cavity
  preparation and cryomodule assembly for
  industrial and lab training

9
Other componentscouplers, tuners, etc

• Develop 1.3 GHz fast ferrite phase shifter tuners
  for ILC
• Get the most of cavity gradients
• Use for high power processing couplers with stub
  tuner..conditioning modules

10
Snowmass Related

• Gather items worthy of discussion at Snowmass
• Should we have a pre-Snowmass meeting for e.g. at
  Cornell SRF2005
• Available time Sunday, Friday afternoon

11
Industrialization

• Set up industrialization workshop, host
  Jlab?LANL?
• We need Jlab to participate in development of
  joint industrialization plan (GDE, SMTF,
  US-regional capability)
• Develop industrialization philosophy
• Develop industrialization plan
• Attract big industries
• Take new industries under wing
• e.g. ADC (Advance Design Consulting) under one
  laboratory wings (Jlab?)
• ADC made cryomodule shells for SNS/Jlab
• Fund specific industrial development studies for
  specific parts of the process, or for specific
  components
• Like DESY coupler study

12
PD type issues (drawn from PD review)

• Is the gradient 26 MV/m assumed for the
  elliptical cavities too near the current state
  of the art?
• o 10 to 400MeV
• 3-spoke, bß0.61, 325 MHz
• or elliptical bß0.47 and 0.61, 1300 MHz
• 400 to 1200 MeV elliptical b0.81, 1300 MHz
• The ß0.47 and (to a lesser degree) the 0.61,
  1300 MHz elliptical cavities have not been
  developed and are quite different from any
  elliptical cavity developed so far.
• Fabricate and test some models? Where?
• Dressed cavities couplers, tuners, cryomodules
• Test 4.5 ms operation

13
CW

• Can we get one of the Rossendorf modules from
  HEPL, shutting down?
• Make plan for CW cryomodule
• e.g. Modify two 7-cell cavities sent to Cornell
  by DESY
• Install two 7-cell cavities sent to Cornell by
  DESY with HOM loads..
