Magnetic Shielding by Thin Walled Superconducting Shells

Abstract

A general discussion of the magnetic shielding strength of thin walled superconducting shells of arbitrary shape in arbitrary fields is given. It is shown that the ratio of the self-inductance of the shell and the kinetic mass of the induced supercurrents (L/m) represents a sufficiently accurate estimate of the shielding strength of the shell. The ratio (L/m) turns out to be an approximately known function of only one essential length parameter which can be determined at a glance for any magnetic screening problem encountered in practice.
