It is thought that an extreme decrease in Ic can be disgarded by a structure called FFDS (face to face double stacked) in which two C.C.s are bonded together. Since the two C.C.s are attached with the superconducting layer inside, it is considered that the superconducting layer is close to the neutral line and has better mechanical strength characteristics than the normal REBCO C.C., so flatwise bending, edgewise bending and twist bending. We will report the result of the mechanical strength evaluation.
