| Abstract: | The gas-cooled current used for HTS AC magnet was optimized based on structure making of two parts with different cross sections, The objective is to minimize their resulting heat leaking into HTS AC magnet, The optimal diameter of down part in current leads is 7.9 mm. Simultaneously, the experiment was done with calorimetric method. The optimal diameter is 8 mm, which is basically agreement with designed one at their top temperature 300 K, down end temperature 77 K and carrying AC current 460 A. Finally, the skin effects of AC current leads are analyzed and discussed. |
