Study of model coils made of superconductor intended for the winding of the T-15 tokamak

After a series of tests of model windings of the current-carrying element intended for the STFW of the T-15 tokamak, it has been established that the material of the winding is suitable for use and has a considerable reserve of stability in stationary regimes and in pulsed perturbations by a longitudinal magnetic field. The currentcarrying element can be used in the STFW of the T-15 tokamak, but the requirements as to ensuring the rigidity of the winding are much more stringent. These tests constitute a portion of the preparation for outfitting the Tokamak-15 and were conducted on a superconducting current-carrying element to study the current-carrying capability of short specimens and to test model coils, full-scale test coils and the facility's regular windings.
