Meeting Outline

• 3-day meeting at FNAL.
• Plenary sessions
• The first day opening.
• The last day close-out
• Otherwise, parallel sessions
• WG1 cavities
• WG2 cryomodules
• WG3 CW and beam testin ? we did not attend
• WG4 PD ? we did not
  attend
• In addition,
• Collaboration board mtg (first day late
  afternoon, with P.Oddone, B.Barish and G.Dugan)
• Technical board mtg (second day noon)
• Non-US participation
• Asian N.Ohuchi (WG2), T.Saeki (WG1) and N.Toge
  (WG2)
• European DESY, INFN, both direct presence and
  via video

SMTF Cavity Status (Mishra)

• 4 units of TESLA design cavities from ACCEL (took
  6 mo to fab) now under mechanical meas/testing at
  FNAL.
• They will be BCPed at Cornell and be tested at
  FNAL with the goal 25MV/m.
• Then they will be EPed at Jlab and be tested FNAL
  with the goal 35MV/m.
• 4 or 8 additional cavities from AES will follow
  the same path.
• They will be dressed, horizontal-tested then
  installed in the first cryomodule.
• Plan exists to augment the EP facility by
  building a new one at ANL for accelerating the
  loop of production-and-processing.

SMTF Cryomodule Status (Mishra)

• Conversion of DESY/INFN drawings (Type-III) into
  US system almost completed (keep metric scales
  adopt US-spec stock items).
• Getting ready to start ordering parts.
• Cryomodule Assembly Facility (CAF) currently in
  preparation at MP9 area (design done, orders been
  placed). It will be used to build the module
  above in FY06-07.

7
Cryomodule Assembly Facility (MP9)

• Cavity will be dressed in CAF for horizontal
  test at Fermilab at PDTF.
• Horizontally tested cavities will be assembled
  into a string at CAF.
• Cryomodule fabrication takes place at CAF.
• Single cryomodule will be tested at the ALCTF.

8
SMTF General (Lockyer)

• In the process of sorting out
• Relations of ILC/PD/RIA/CW components among SMTF
• Relation of SMTF w.r.t GDE and world ILC
  activities in other regions.
• Looking for a new name for the whole group
  (STELA?). And for individual projects (e.g.
  ILCTA, ILCTF etc)
• Exploring ways to facilitate the growth of SRF
  capabilities in all three regions for ILC, e.g.
  three meetings per year with commonly shared
  agenda.

Toges Personal Remarks (1)- Observations -

• There will be a big pressure to start serious
  international discussion in late 2005-early 2006,
  for the next-stage ILC cryomodule development.
• NA group is trying to ready themselves for that.
• Likely scenario
• Formally start international design work in 2006,
  
• intensity that in 2007, and
• move on to the construction, assembly and testing
  following these.
• Important prerequisites
• NA and AS teams to rapidly accumulate experience
  and thoughts.
• In case of AS, sufficiently strengthen the
  cryostat team.
• GDE figures out how to institutionalize the ILC
  collaboration framework under GDE.

Toges Personal Remarks (2)- Possible Action
Items -

• We should draft our Phase-2 cryomodule plan.
• Straw-man version of next-stage cryomodule that
  we need towards ILC.
• Pay attention to outcome at Snowmass2005, SMTF
  last week and BCD. If appropriate, submit inputs.
• Determine how it relates to STF Phase-2
  cryomodule plan.
• We should draft our international collaboration
  plan in FY2006 and beyond.
• Technical aspects (e.g. what to build, how to
  test, what to verify)
• Organizational aspects (e.g. how to discuss, how
  to share, how to parallelize)
• We should submit proposals at Frascati and/or
  Bangalore, and take an initiative.
• Do all three above, while keeping Phase-1 in pace
  and strengthening our SRF team particularly the
  cryostat area.
