Abstract :
The study on the critical current dependencies on magnetic field values in the range 3-12 T and on temperature in the range 4.2-15 K of Nb3 Sn strands samples is presented. It is shown that experimental values of Ic(T, B) are well described by relation of Summers with the deformation of -0.25%. The results of volt-temperature characteristics measurements taken in magnetic fields at different currents of a sample are given. The analysis of the dependencies has been done.
