Copper layer thickness for 325 MHz superconducting cavity input couplers
-
摘要: 通过对工作在325 MHz、镀铜厚度分别为10，20，30 m的耦合器外导体进行高功率测试，研究了超导腔输入耦合器外导体内壁镀铜层厚度与漏热的依赖关系，目的在于寻找最优化的铜层厚度来降低超导腔输入耦合器的低温漏热。实验结果表明，20 m铜层的耦合器具有较低的动态损耗。综合考虑静态损耗与动态损耗，则20 m铜层厚度为最优化的铜层厚度。Abstract: This article studies the relationship between the copper layer thickness of the outer conductor of superconducting cavity input coupler and the heat leak.We compared copper coatings of 10，20，30 m respectively of 325 MHz coupler through high power test and aimed to find the optimum thickness of the copper plating layer in order to decrease the cryogenic heat load . The experimental results show that 20 m layer has lower dynamic heat leak. Considering both static heat leak and dynamic heat leak, the 20 m thickness of copper layer is the optimum one.
