“After
correcting for the higher
Cu:non-Cu ratio the WST strand is about 7% more performance than the MB outer layer strand.”-Matthias9Q. Xu, 2019 CERN-China Collaboration Meeting
Slide10Schedule of WiresThe Schedule of NbTi Wires for Next 12 SeriesThe coils for one magnet need ~10 km wire.
For the prototype, 13.5 km wires are sent to CGP for insulation, and 13 km wire was used in total because of breakdown points after
insulation.200 km wires will be prepared for next 12 series.

Slide26Quench Detection System
TheTwo
asymmetry
voltage bridges are used as the judgement signals to avoid possible symmetry quench.Quench detection system is based on the NI-cRIO platform.The logical calculus is carried out by FPGA. The isolation module is used to protect the electronic equipment.When the quench is detected, a 24V quench signal will be sent to trigger the quench
protection
switch and the data acquisition system.
