Insulation system test for the KSTAR central solenoid (CS) model coil

The insulation system for a tokamak superconducting magnet should ensure the mechanical and electrical reliability and must have resistance to the radiation environment during operation. The winding scheme of the whole KSTAR (Korea Superconducting Tokamak Advanced Research) CS (central solenoid) coi...

Description
Summary:The insulation system for a tokamak superconducting magnet should ensure the mechanical and electrical reliability and must have resistance to the radiation environment during operation. The winding scheme of the whole KSTAR (Korea Superconducting Tokamak Advanced Research) CS (central solenoid) coil using Nb/sub 3/Sn CICC (cable in conduit conductor), it is found that there is considerable shear due to tensile force. To obtain a proper resin system two candidates were tested and compared with the ITER (International Thermonuclear Experimental Reactor) standard resin system as a benchmark. This work includes viscosity measurement, flexural strength, shear strength and thermal contraction at room temperature and 77 K. Test procedures and the results of each measurement are presented.
