Toshiba demonstration coil 9/23/20139 Fabricated at Toshiba 2012 Shipped to Fermilab in December Indirect Cooling at Fermilab

TS Prototype 9/23/ Collaboration with INFN/Genoa - ASG

TS Conductor 9/23/ target I c (4.2K,5T)=494A All samples exceeded specifications Very good agreement between measurements collected at Fermilab and Hitachi. The complete set of cold and warm measurements (not fully reported here, including wire diameter, ovality, cu-SC ratio, twist pitch, critical current, n-Value, RRR, filament diameter and spacing, sharp bend test…) was performed in-house on each length and internally reviewed before accepting the wire.

Schedule Prototype lengths of the SC delivered by October-December 2013 TS Prototype finalized by March 2014 The bid process for the larger solenoids by the end of /23/201312
