ABSTRACT:
A superconductive switch for a superconductive magnet is bifilarly wound on a bobbin with niobium-tin tape and laminated with stainless steel foil for structural rigidity is provided. The switch is vacuum pressure epoxy impregnated and cooled by copper bus bars which are heat stationed to a cryocooler which is also used to conduction cool the superconductive magnet. The bus bars are also used to introduce a voltage across the switch and the magnet windings which are connected in series with one another to ramp up the current.
