Summary :
Magnetic shielding is a key technology for super-conducting RF cavities.It is necessary to optimize the shielding method, including the choice of materials and the shape of the magnetic shield, and to establish a method for quality control suitable for large-scale production.We plan to continue to evaluate the permeability of various shielding materials, and also investigate possible causes for the performance degradation of the shielding material at cryogenic temperature. We would also like to study the dependence of cavity performance on the permeability
