Abstract

Superconducting transposed cables with different transverse resistivities have been investigated. These cables consist of NbTi-Cu wires with different coatings. The magnitude of interwire resistance has been varied from 10^-3 up to 10^-7 Ω. The methods and results of measuring the transverse resistance and its dependence upon compression and external magnetic field are discussed. On the basis of the results obtained, the construction of the cables with the anisotropic transverse resistance providing a high stability level is proposed. The coupling losses in the cables with different transverse resistances have been measured. The proposed construction of the cables should provide reduction of coupling losses by a factor of 10 ²-10³ as compared with soldered cables
