11 T Project Meeting

Update from Task 35.5 m Cold Mass

December 17th, 2013 – F. SavaryWith contribution from S. Luzieux, R. Moron Ballester, and D. D. Ramos

Update from Task 3 - 5.5 m Cold Mass 2

Plan regarding cold mass design Have a baseline, or conceptual design, by the end of 2013

Integrated cold masses (common cryostat) … or Separated cold masses (each cold mass would have its own

cryostat, also independent from the collimator) Integrated (meaning passing through the cold mass) or separate bus

bar routing Flat or dished end covers …

Have a preliminary design by mid 2014, including a clear definition of the main dimensions, and of the various interfaces, meaning a preliminary technical specification for the cold mass assembly

Thereafter, start developing details towards a final design, and identify critical components in terms of procurement

Update from Task 3 - 5.5 m Cold Mass 4

About bb routing Challenging … obviously

space limitations! Integration of spool pieces (MCS)

Make things difficult for the integration of the bb lyras to the left of the collimator (seen from the center of the machine) … even if only for 15 mm stroke

But also to the right, because spool pieces take more space than internal connections

Mirror cold masses would mean two ‘connection’ ends on either side of the collimatoro This may help … but

• We do not gain in space if spool piecesare needed at these locations

• The diode stack is on the connection end, and requires access for possible intervention

o Some flexibility would be needed anywaybetween the two cold masses

Tooling WP1 (winding, binder curing)

Tension meter broken during testing, need to be repaired Second layer spool holder, fabrication on-going, delivery end of Jan.14 Mandrel/poles/shells/pushers, fabrication on-going, delivery end of Feb.14 Binder curing mold, design needs to be refined. Order in the beginning of 2014,

delivery planned in the end of Apr.14) Handling tools / girder, design finished this week. To be ordered in the beginning

of 2014 WP2 (reaction treatment, instrumentation, and coil impregnation)

Reaction tooling (based on short model concept), drawings to be made in the beginning of 2014. A study aiming at understanding better gas shielding (protection of the coil), and possibly optimizing the reaction tooling will be launched a.s.a.p. in 2014

Design of handling tools/girder for the reaction treatment will start in the beginning of 2014

Design of impregnation tool, pressure leak tight, will start in the beginning of 2014 Splice tooling will be an adaptation of the one currently used in B927
