SMTF Meeting Report(Oct.5-7, 2005, FNAL)

Oct. 14, 2005 KEK/ILC-Asia WG2 mtg

Nobu Toge (KEK)

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 a

nd 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.

• 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.

SMTF Cryomodule Status (Mishra)

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.

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.

9

• 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 f

ramework under GDE.

Toge’s Personal Remarks (1)- Observations -

Toge’s 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 p

arallelize)• We should submit proposals at Frascati and/or Bangalore, and t

ake an initiative.• Do all three above, while keeping Phase-1 in pace and strength

ening our SRF team particularly the cryostat area.
