“…Shielding properties of Type-II superconductors can be exploited in a variety of ways: field shaping [2,3], field concentration [4], measurement devices [5,6], and interfering field suppression [7]. For the last category, the superconductor can work according to the field level either in the Meissner or in the mixed state [8].…”

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

“…There is a wide range of applications of superconductors to shield [2][3][4][5][6][7] or shape [7][8][9] magnetic fields. Some unique challenges of the current application are as follows: (i) The bulk superconductor must fulfil these two functionalities simultaneously: completely shield the field at the location of the circulating beam, and shape a homogeneous field in a region of about a few cm outside the shield.…”

A zero-field cooled superconducting shield is proposed to realize a high-field (3-4 T) septum magnet for the Future Circular Collider hadron-hadron (FCC-hh) ring. Three planned prototypes using different materials and technical solutions are presented, which will be used to evaluate the feasibility of this idea as a part of the FCC study. The numerical simulation methods are described to calculate the field patterns around such a shield. A specific excitation current configuration is presented that maintains a fairly homogeneous field outside of a rectangular shield in a wide range of field levels from 0 to 3 Tesla. It is shown that a massless septum configuration (with an opening in the shield) is also possible and gives satisfactory field quality with realistic superconducting material properties.
