“…The critical current ( ) of AFM conductors was measured in liquid nitrogen (LN ) and as a function of temperature between 77 K and within a nitrogen atmosphere, by means of the experimental apparatus described in [5]. has been determined by the 1 V/cm electrical field criterion and the temperature measured by T-type thermocouples evenly distributed along the specimens.…”

“…AFM conductors have been tested in LN and at higher temperature by means of the experimental apparatus described in [5], [8] where the AFM composite conductor under investigation is conduction cooled by two copper tube supports that are partially immersed in a LN bath. The AFM conductor is initially held at a constant temperature 78 K K and then a current in excess with respect to value is applied and kept constant to drive the HTS in a highly dissipative regime.…”

Current leads incorporating high-temperature superconductors (HTS) have the potential to greatly reduce the refrigeration requirements with respect to conventional leads. However, lead-design considerations include not only electrical and thermal performances of the HTS section, but also its structural integrity and reliability. In this paper, characteristics of low-loss AFM BSCCO-2223/AgAu composite conductors and the influence of thermal cycling between room temperature and 77 K on their critical current are presented and discussed.

“…The current interest paid to multilayered structures (in connection to its fabrication, and applications concerning superconductivity, skin effect, eddy currents, and photonic metamaterial structures) is witnessed in recent publications [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Nonetheless, the research topic on multilayered radially inhomogeneous cylindrical structures has received scarce attention.…”

Abstract-A matrix technique for the computation of the perunit-length internal impedance of radially inhomogeneous cylindrical structures is presented. The cylindrical structure is conceptually divided into a number of layers, each layer being characterized by its constitutive parameters, conductivity, permeability, and permittivity. Within this general framework, compound conductors, compound capacitors, compound magnetic cores, or any other compound structures resulting from a mix of the above, can be analyzed by using the very same tool. The developed software program, MLCS, which implements the mentioned matrix technique, also permits the evaluation of the electric and magnetic fields intensity at the layers' interfaces. The MLCS program is validated by using several application examples.
