Abstract

We need very high magnetic field and hence large Superconducting Magnet to meet a demand of ITER (International Thermonuclear Experimental Reactor). So we need high rigidity SC magnet, which contribute the accuracy of the generate magnetic field. To design the high rigidity magnet we need firstly to estimate the rigidity of SC magnet from its form, dimension and the number of turns and layer. At a glance the basic unit of the rigidity seem to be each conduit. But we found that is false in experiment and FEM. So we defined proper basic unit of the conductors, and made it connected with full model of SC magnet conductors. This method of evaluating can be applied any other new developing form conductors and magnet.
