EAST ICRF天线保护限制器热分析

In consideration of the structural safety of the guard limiter on EAST ICRF antenna, the thermal analysis for the guard limiter was performed using the finite element method(FEM).The results of temperature distribution on the guard limiter was presented and studied, and the result will provide theoretical guidance for physical experiments in the future.Inaddition,the structure of the guard limiter was improved, and the thermal analyses were performed for the new guard limiter under the same conditions.Results of the analysis demonstrate that the new guard limiters are better than the original one.
