Abstract
A superconducting apparatus comprises a superconducting coil, a cryogenic fluid for cooling the coil, a vessel for enclosing the superconducting coil and the cryogenic fluid, a current lead penetrating into and supported by the vessel and electrically connected to the superconducting coil, and an electrically insulating tube disposed around the current lead. The insulating tube includes an electrically insulating ring disposed around the current lead between the vessel and the current lead and outside of the vessel for electrically insulating and hermetically sealing between the current lead and the vessel, a hollow electrically insulating cylinder disposed around the current lead, and means disposed between the insulating ring and the cylinder for continuously connecting the ring and the cylinder thereby to substantially close any gap therebetween against electrical discharges therethrough.
