Abstract: With the technical upgrade of the EAST high-temperature superconducting current lead, the support structure in the current lead tank was redesigned optimally, its structural stability analysis was carried out, and finally the optimal design scenario was determined according to the analysis results. The optimized design of the current lead canister is tested, and its result shows that the support structure can better ensure the safety and stability of the current lead. 

Key words: Current lead tank, Supporting structure, Optimal design, Stability analysis
