Strand Testing • SQXF will use 108/127 Ti-Ternary strand from 10 billets • 5 billets have “reduced-Sn” to improve RRR • Determine appropriate reaction temp/time for coil reaction. • HT study using 640 C/72 h • Ic(12 T), Ic(15 T) and RRR measured for 10 wires, 0. 85 mm diameter, along with a 132/169 design wire with “standard-Sn” for future reference • Results indicate that for the 108/127 wires with “standard-Sn” we will use 640 C/48 h to ensure RRR > 100. For “reduced-Sn” 640 C/72 h is recommended for better Ic match with the “standard-Sn” billets • Witness samples tests • HQ-C 26 reacted at BNL (on-going) • LHQ-C 03 reacted at BNL (will commence next week) • LARP MSM 20140109 Conductor, Cable and Procurement - A.

QXF - Cable • Fabricated B 1048 Z and B 1049 Z • Strand

QXF - Cable • Fabricated B 1048 Z and B 1049 Z • Strand is 108/127 Ta-Ternary • 1048 Z uses wire “as-received” • 1049 Z uses same wire annealed at 170 C/14 h • Cable insulated with S-2 Glass® braided at NEWT • Insulation thickness 0. 143 mm and 0. 141 mm, specification target is 0. 145 0. 005 mm. • Cable is being used for winding tests with end-parts designed by ROXIE and BEND. • Fabricated B 1050 Z, 190 m for first practice SQXF coil using “as-received strand”, 108/127, Ta-Ternary • 175 m of cable will be sent to NEWT for insulation • B 1051 Z using annealed strand will be fabricated in Jan’ 14. • At a CERN-LARP Conductor meeting it was decided that CERN will fabricate Nb-Ti cable for all leads using 1. 085 mm LHC “surplus” wire.

Strand Procurement • 275 kg LARP order • 20 kg delivered as 108/127 • 255 kg will be delivered as 132/169 • Change order has not been executed as we are waiting on OST for a quote for the 132/169 • Delivery will be made in Apr’ 14 • 180 kg CDP order for 144/169 with “reduced-Sn” • Recent change • Item 1 : 45 kg of 132/169 with “standard-Sn” (strand similar to that being made for CERN order). Delivery Jan-15 th-2014. Quantity sufficient for 1 unit length of SQXF cable • Item 2 : 140 kg of 132/169 with “reduced-Sn” delivery in May’ 14 • 90 kg CDP order for 132/169 with “standard-Sn” and thicker barrier • Delivery expected in June’ 14 LARP MSM 20140109 Conductor, Cable and Procurement - A.

Other Items • Drafting specification for fiberglass braided cable insulation • LARP-MAG-R-8006 • Have received feedback from vendor • Intent to issue Rev-A for all insulation work beyond cable B 1050 Z. • Insulation procurement to be done from FNAL (Steve Krave) • Drafting specification for Cable • LARP-MAG-M-8005 • Need to capture parameter requirements, testing methods and QA documentation from cabling facility • Goal is to issue Rev-A before the LARP collaboration meeting.
