Development and creation of powerful cryogenic electromagnetic systems (superconducting and hyperconducting windings)

A physical model of current flow in from high-purity aluminum giperprovodnike, taking into account the effect of the magnetic stray field of the self-field coil, which allowed to optimize the design of the winding because of its banding on the mechanical loads and flow-through cooling with liquid hydrogen. When choosing a winding structure the main criterion is to protect the plastic guide from the radial and axial strain. This is ensured by a special coil banding and strong material allows to maintain the high conductive properties of high-purity aluminum and provide a current density of 200 A/mm. Obtained at this stage of the assignment results confirm the fundamental possibility of generating strong magnetic fields in compact solenoidal systems promising for use in power systems on board spacecraft.
