Abstract

This paper presents a novel empirical formula for evaluating the axial magnetic attenuation of a circularly cylindrical shield with partial openings at both ends, which is derived under the assumption of scaling law with help of the 3-D magnetostatic code TOSCA for computing the magnetic attenuation of some canonical models. Our formula allows a quick evaluation of the magnetic shielding for design application to a superconducting radio-frequency cavity with less than 10% discrepancy in comparison with that obtained from pure numerical simulations.
