Superconducting windings with parallel connected sections

A theoretical treatment of superconducting magnets with parallel connected sections has been performed. The method and results of calculation and optimization of magnet geometric and electromagnetic parameters is described. It is shown that by selecting the dimensions of sections with due regard for the superconductor critical current dependence on the magnetic field the conductor consumption can be markedly reduced. Main regularities of the quenching process in a sectioned winding are found. It is shown that segmentation improves the reliability of winding, especially in the case when the normal zone is localized in one section of the magnet. Criteria of segmented magnet reliability based on the parameters of constituent modules are found.
