Geometry dependence of superconducting shielding for sensitive detectors

Superconducting shielding is a powerful technique for shielding detectors. However, it is sensitive to details of geometry. This paper uses the geometry of the shielding of the submillimeter and far infrared experiment (SAFIRE) as a basis for study. Shielding tests are performed on three different geometries of niobium - disk, ring and tube. Attempts to model the superconducting shielding are also made and compared with measurements.
