Abstract
The manufacture of windings from all superconductors that appeared after wires based on the niobium-titanium alloy has been associated with overcoming difficulties due to their brittleness. The design, manufacturing process, and expected properties of helical windings are described. It expands the application capabilities of fragile materials. The proposal will allow manufacturing windings of various shapes without exceeding the critical deformation for the superconducting layer. The winding is protected and controllable. One of the possible schemes for manufacturing a helical substrate for sputtering layers similar to those of second-generation HTSC tapes is described.
Keywords: helicoidal winding; helicoidal substrate; material equation.deformation; controllability.
