Abstract

In order to fabricate the central solenoid (CS) and equilibrium field (EF) coil conductors for JT-60 Super Advanced (JT-60SA), the jacketing facility of 680 m was constructed at Naka site of Japan Atomic Energy Agency. The dummy copper conductors of 10 m and superconductors of 7 m were fabricated. The attachment sleeve to connect the cable and winch wire to pull cable through a 551 m jacket in maximum was developed. The sleeve attained the 30 kN of pulling force. In order to investigate the strand damage by the edge of central spiral through compaction and bending process, the measurements of strand critical current in prototype EF conductor with bending curvature radius of 150 mm was conducted. The degradation of was not observed.
