摘要： A vapor cooled current lead for a superconducting device located in a cryostat includes a normal conductor section extending from ambient conditions inward to an intermediate point, and a composite lead having a ceramic high temperature superconductor core with a metallic sheath extending between the normal conductor section and the superconducting device, preferably in a helical path to reduce heat leak by conduction. The metallic sheath is stripped away at spaced intervals, preferably adjacent the low temperature end of the composite lead, and the gaps are filled with a filler which provides mechanical strength for the core and reduces thermal conduction. A flow of cryogen vapor directed by a tubular housing maintains the high temperature superconducting material below its critical temperature, and cools the normal conductors.

摘要： A power lead for a cryostat has high temperature superconducting (HTSC) conductors extending inward toward a pool of liquid cryogen in the cryostat in series with normal conductors extending from the HTSC conductors to outside the cryostat. Tubular shrouds vented to atmosphere direct a flow of cryogen vapor along the HTSC conductors to maintain them superconducting, and along the normal conductors to remove Joule heat and heat leakage along the normal conductors. In one embodiment, a pool of liquid nitrogen maintained within a tubular inner shroud is the principal coolant for the normal conductors. Helium vapor is circulated over the HTSC conductors and is then directed by an outer tubular shroud around the inner tubular shroud to provide additional cooling for the normal conductors. Flexible connectors at one end of each of the HTSC conductors accommodate for individual thermal contractions of these conductors.

摘要： A multiple circuit hybrid cryostat power lead has a plurality of laterally spaced, electrically isolated lead elements inside a tubular enclosure. Each lead element has an inner section with a high temperature superconducting (HTS) conductor inward of a divider in the tubular enclosure, and an outer normal conductor section outward of the divider. The outer sections of the lead elements have a pair of copper conductors spirally wound in an annular chamber between an electrically insulating central support and an electrically insulating sleeve to form helical flow passages. Cryogen vapor flows outward in the tubular enclosure inward of the divider over the HTS conductors, through a slotted heat exchanger electrically connecting the HTS and copper conductors at the divider, and through the helical flow passages to vents at outer terminals. Flow distribution in the helical passages is regulated either by a flow baffle diverting flow at an intermediate point in the helical flow passages through apertures in the sleeves into the tubular enclosure for mixing and reintroduction of the mixed cryogen vapor back into the helical passages through additional apertures in the sleeve outward of the flow baffle, or by individual thermally responsive valves in the flow passages.

摘要： A current limiting device including a housing in which a chamber is formed. A pair of spaced electrical terminals are located at opposite ends of the housing to be disposed in communication with the chamber. An electrically conductive fusible metal is disposed in the chamber to provide an electrically conductive path between the terminals. An insulating member is disposed in the chamber between opposite ends of the housing to define a flow passageway between the electrical terminals. The flow passageway may include a constricted portion that has a cross-sectional area and a length that is substantially less than the rest of the flow passageway defined by the insulating member such that with the occurrence of a fault current, vaporization of the fusible metal initially occurs in the constricted portion of the flow passageway. Expansion means are also provided for buffering the pressure rise in the chamber when the fusible metal is vaporized.

摘要： A safety switch for use in an inductively driven electromagnetic launcher system includes three tubular conductors each having a substantially cylindrical internal surface, wherein these internal surfaces have substantially the same internal diameter and are positioned at spaced locations along a common axis. A fourth tubular conductor having a cylindrical external surface with a diameter which is substantially equal to the internal diameters of the first three conductors. This fourth conductor is mounted for movement along the common axis such that its external surface is capable of making sliding electrical contact with the internal surfaces of the first three conductors. The external surface of the fourth conductors has sufficient axial length to be capable of making electrical contact with each of the internal surfaces simultaneously. Means are provided for electrically connecting the first three tubular conductors to an external circuit and a switch actuating means serves to move the fourth tubular conductor axially along the common axis.

摘要： A control system for a linear motor adapted to accurately supply a moving window of power to the stator coils. A plurality of individually switched stator coils run the length of a linear motor to move a rotor down the long axis of the stator. Accurate inductive-based position sensors continuously provide position data for the moving rotor. A processing unit calculates a proper time delay from a source voltage peak in order to apply power to the next stator coil in the moving direction of the rotor such that no DC offshoot/undershoot occurs. The linear motor control system optionally includes a failure prevention switching scheme in which pairs of individual stator coils on opposite sides of a double-sided stator are switched together.

摘要： A projectile launch package for use in electromagnetic launching systems is provided with separable armature and projectile assemblies. The armature assembly includes a conductive element which initially conducts accelerating current. After a certain time, the conductive element fuses, thereby forming a plasma which further accelerates the projectile assembly. Following the plasma initiation, the armature assembly is expelled from the launcher under its own momentum.

摘要： An integrated switch-preaccelerator system for use in an electromagnetic launcher includes a pair of spaced generally parallel preaccelerator rails, a pair of spaced first and second conductive switch terminal elements disposed adjacent upstream ends of the rails, and three coaxially arranged conductive tubular members enclosing and extending axially along the rails, one of which being movable relative to the others between conducting and non-conducting positions. The terminal elements and selected ones of the tubular members are electrically connected together such that movement of the one tubular member from its conducting position to non-conducting position causes operation of the switch to commutate current from a first path wherein current flows from the first to the second terminal element by flowing through the tubular members in opposite directions along path segments spaced from and coaxially arranged about one another to a second path wherein current flows from the first to the second terminal element by flowing through portions of the rails and a solid armature being supported therebetween and bypassing the tubular members.
