Status of cable production at CERN (1/2)15.1 mm, 40 strands cable produced in 2010 and beginning 2011 (0.7 mm Cu and OST 108/127 stack material)Stable key-stoned cabling at pitch 90 mmAverage cabling degradation on OST 108/127 0.7 mm stack is 2.7 % at 12 T, 4 % at 11 T (good)Maximum single strand degradation observed is 7 %May 13, 2011 Collaboration meetingM. Karppinen CERN TE-MSC5
Status of cable production at CERN (2/2)14.7 mm, 40 strands tools being finalized (mandrel OK, rollers to re-touch). Cabling imminentOST 108/127 0.7 mm strand order status4.7 km delivered (Jc > 2500 A/mm2, RRR 70)25 km expected by May 31st (delivery to be verified)Bruker PIT 0.7 mm strand order statusSpecifications preparedMeeting at Hanau on May 31st

Cable Insulation DevelopmentS-glass braiding (on 4.5 mm cable)May 13, 2011 Collaboration meetingM. Karppinen CERN TE-MSC7
Coil Fabrication Tooling The Fermi mandrel design is being adapted to our winding and curing tooling. The mandrel blocks have been redrawn and converted metric & ISO. Price enquiry to launch this week. MB (Jeumont) curing moulds will be used for curing the binder Spacers, oil circuits connections, coil handling tools to designMay 13, 2011 Collaboration meetingM. Karppinen CERN TE-MSC8
Winding ToolingMay 13, 2011 Collaboration meetingM. Karppinen CERN TE-MSC9
End SpacersCNC-machined set #1 complete (minimum strain design)Lead-time at CERN 8-10 weeks/setIndustrial procurement:3 offers for 5-axis machining (to confirm after decision on spacer design)Lead-times 6-10 weeks for the 1st setRelatively high programming and tooling costSLS as fallback solution May 13, 2011 Collaboration meetingM.
