In order to reduce the reaction force of support, crank shaped feeder and piping were designed. The crank shaped feeder reduces the reaction force of support to 10% of zigzag shaped feeder. Because of the limited space in torus hall, many interfaces of feeder and piping are located at upper part of tokamak. Feeders and piping have to manage large displacement of interface by adding bending. One box type electrical joint was developed with good reproducibility of electrical resistance below 3 nΩ even though different connecting positions and manufactures. Five coil terminal boxes, eleven valve boxes, components of cryoline and control system were manufactured already. These components will be installed in torus hall in 2019., 第27回核融合エネルギー会議}, title = {Progress in Design and Fabrication of Current and Helium Feeding System for JT-60SA Superconducting Coils}, year = {2018} }
