Monte Carlo simulation of strand position in CIC conductor

The strand position in CIC conductor has been calculated three dimensionally by using Monte Carlo method. The 1152 (3 × 4³× 6) Nb₃Sn superconducting strands were packed in the conduit. The manufacturing process of CIC conductor was simulated. The six 4th-stage cables were cabled with a spiral tube and then packed into the conduit. The conduit was compressed with the cable to fix the size and the shape. The conduit was compressed from one end and so that the strands were stretched along the axis unevenly. The contact energy between strands and the strain energy in the strands were considered. It was confirmed that the strand positions were changed by compressing the conduit and the obtained strand positions were similar to those in actual CIC conductor.
