Superconducting Spherical Magnetic Shields on the Basis of Niobium and Its Compounds

摘要

The method of fabrication of superconducting spherical magnetic shields on the basis of superconducting electrolytic coatings made of niobium, Nb_3Sn, and NbC is developed. These shields can be used for weakening the external magnetic fields with strength up to 800 kA/m and obtaining a magnetic vacuum lower than 0.8×10~(-5) A/m.
