 note = {The inhomogeneous poloidal magnetic field of tokamak
device, which is called error field, has to be reduced because
the error field degrades the plasma performance. There are 18 sets
of EFC coils installed inside the vacuum vessel for JT-60SA to
compensate the error field. The conceptual design of EFC coils
has been completed. The water-cooled hollow copper conductor
was selected to reduce the conductor size since the available space
for EFC coils is small. The outer size of the conductor and the
diameter of the cooling channel were optimized in considering
hydraulic and thermal characteristics. The design of the conductor
was validated by the testing of a mock-up coil. The bar springs
are used for the structure of EFC coils. The structural analysis
was performed to optimize the parameters of bar springs. The
results of structural analysis suggest that the structure of EFC
coils can be used for both the conditions of plasma operation and
baking operation with the use of Inconel625 for bar springs. In this
paper, the specification of the JT-60SA EFC coils, the test results of
mock-up coils, and the structural analysis results of the EFC coil
structure are described. The manufacture of EFC coils has started
based on these designs.},
