CEA KE 2775 progress meeting WP3 – FRESCA 2 Magnet Françoise Rondeaux – Paolo Ferracin 17/12/2014 CEA-Irfu-SACM-LEAS - F.Rondeaux -CEA KE2775 progress meeting - WP3

Status 2 copper coils already partially done : CC3401 (type 3-4): winding OK, sent to CERN (25/06/2013) heat treatment OK impregnation OK CC1201 (type 1-2) winding OK, sent to CERN (07/01/2014) impregnation in progress 17/12/2014 CEA-Irfu-SACM-LEAS - F.Rondeaux -CEA KE2775 progress meeting - WP3

Modified winding / reaction tooling We have received the modified winding / reaction tooling (in 3 parts) for type 3-4. Test on coil (4+4 turns of RRP cable) with modified tooling + large gaps (DR3401) : OK, cf. next slide Test on coil (4+4 turns) with modified tooling + adjusted gaps (DR3402) : winding OK, waiting for the new guiding rings Procurement of the modified tooling for type 1-2: delivery in early April 17/12/2014 CEA-Irfu-SACM-LEAS - F.Rondeaux -CEA KE2775 progress meeting - WP3

DR3401 It moved! 1,9 mm sym side + 1,3 mm asym side ¾ ceramic guiding rings broken will be modified 17/12/2014 CEA-Irfu-SACM-LEAS - F.Rondeaux -CEA KE2775 progress meeting - WP3

Milestones 2 options: 1) strategy maintained with intermediate test. 2) without intermediate test (and CC3402). Planning modifications (option 1): - modifications in tooling after DR3401. - modified tooling 1-2 delivery delayed. - need to wait disassembly of coil pack CR12+CC34 Option 1 Kick-off meeting  Today 3.1 : 1 Cu coil type 3-4 with modified tooling March 2015 June 2015 3.2 : 2 Nb3Sn coils type 1-2 for FRESCA 2 magnet delivered September 2015 December 2015 3.3 : 2 Nb3Sn coils type 1-2 tested with 2 Cu coils February 2016 May 2016 3.4 : 2 Nb3Sn coils type 3-4 for FRESCA 2 magnet delivered 3.5 : FRESCA 2 magnet tested August 2016 November 2016 17/12/2014 CEA-Irfu-SACM-LEAS - F.Rondeaux -CEA KE2775 progress meeting - WP3

Milestones 2 options: 1) strategy maintained with intermediate test. 2) without intermediate test (and CC3402). New order for the coils fabrication Cable available for CR3401 in March? Option 2 Kick-off meeting  Today 3.2 : 2 Nb3Sn coils type 1-2 for FRESCA 2 magnet delivered September 2015 November 2015 3.4 : 2 Nb3Sn coils type 3-4 for FRESCA 2 magnet delivered February 2016 3.5 : FRESCA 2 magnet tested August 2016 June 2016 For both options: - end of test DR3402 : new guiding rings - coating of the post - availability of new horseshoes (tooling) and cable supports : validation of splicing zone 17/12/2014 CEA-Irfu-SACM-LEAS - F.Rondeaux -CEA KE2775 progress meeting - WP3
