description | A method for designing cylindrical hollow superconductingshields for cryogenic measurement devices operating in background fields of1 T is proposed. The shield design is based on MgB2 composite,manufactured by the reactive Mg liquid infiltration process [1]. TheMgB2 composite allows low-cost shields with good mechanical resistanceto be realized easily. The geometrical design is benchmarked by theexperimental characterization at 4.2 K. A design case study for the shieldof a cryogenic DC current transformer is reported. Design results show ashielding efficiency of 70% for both the axial and radial components,with prospective measurement accuracy up to 10 ppm on 100 kA. |
