Abstract

Experimental and finite element model studies of magnetic shielding characteristics of one-side planar sheet structures of the second generation high-temperature superconducting (2GHTS) coated conductor tapes show that significant shielding can be achieved. The shields are shown to be useful for attenuating noise and enhancing the measurement accuracy of magnetic fields. The shields are particularly important for shielding the perpendicular component of the noise during the measurements. The location of the sensor with respect to the shield and the dimensions of the shield need to be designed appropriately to achieve the needed measurement accuracy. The number of superconducting layers in the shield is a design parameter that depends on the magnitude of the noise. The experimental results on shielding factor of a single layer sheet agree with the results of the finite element model.
