Abstract

The KSTAR central solenoid (CS) coils consist of 4 pairs of superconducting coils, which have up-down symmetry and a set of structure with electrical insulation. The structure gives pre-compression in a vertical direction on the coil stack to sustain the contact between coils. The CS structure has the important design requirement that it should protect the CS coils from electromagnetic and thermal loads. The space inside the CS coil has complicated components such as long coil leads and cooling lines and there are many limits in designing the supports. Thus, in order to solve the interference problem between other structural components, a design for the CS structure has been proposed. Also structural analysis has been performed to verify the structural integrity.
