A research on the optimum parameters for multishell cylindrical magnetic shields

This paper gives a general theory of shielding efficiencies for magnetic shields including single-layer and multishell cylindrical ones. The differences of shielding efficiencies between multishell cylindrical shields with and without endcaps are also discussed. The optimum parameters (the innermost radius and length and radial and axial air gap) for five-shell cylindrical magnetic shields are expressed here after a detail theoretical analysis. While three of the four parameters are fixed, the optimum value of the last one is found. The residual magnetic field inside a set of three nested magnetic shields is measured experimentally, which is found to agree well with the theory.
