摘要： A high temperature superconductor fault current limiter and a method of using same. The fault current limiter comprises a high temperature superconductor material structure at least partially encapsulated in an epoxy having thermal conductivity properties that enable the superconductor to heat rapidly during a fault condition while preventing thermal runaway. The epoxy encapsulation decreases the critical current density of the superconductor material structure and increases the rate at which resistance increases with increasing current once the critical current density is exceeded. Preferably, the epoxy has thermal expansion properties approximately equal to the thermal expansion properties of the superconductor material structure.

摘要： A method of measuring a cryogenic fluid level utilizing a high temperature ceramic superconductor material driven above its level of critical current density. A high temperature ceramic superconductor is placed in cryogenic fluid and a voltage is applied between two points on the superconductor. The voltage drop is then measured at a third point on the superconductor. This voltage drop corresponds to the change in cryogenic fluid level, and thus can be used to measure the fluid level. Sensitivity of the measurement is increased by driving the high temperature ceramic superconductor above its level of critical current density.

摘要： An improved process for preparing superconducting ceramic powder includes calcining superconducting precursor compounds in an atmosphere having a controlled amount of oxygen, generally not more than that found in air, the remainder of the atmosphere composed of a gas or mixture of gases inert with respect to the ceramic. A preferred process includes forming the precursor compounds into a slurry, granulating the slurry, drying the granules (a binder can be added to the slurry to promote green strength), and calcining in the controlled atmosphere to provide the desired HTSC (high temperature superconductor) composition.

摘要： A high rate lithium battery can include a cathode composition coated on a substrate. The cathode composition can include first and second active materials and binder. The first and second active materials can have different characteristics including, for example, particle size, tap density, and amount of conductive component. The first and second active materials can be combined to achieve higher packing densities of the active material, which may allow for a higher capacity battery as compared to conventional batteries formed with a single active material.

摘要： A stripline resonator has a center conductor between layers of dielectric which are, in turn, between ground planes. The center conductor is made of a high-temperature superconducting material, preferably having a total superconductor thickness from at least about one micron to at least about one-hundred microns. The superconducting material has an electromagnetic penetration depth and the ratio of the thickness of the superconductor to the penetration depth is from at least about 4:1 to at least about 100:1. The center conductor may be formed of a substrate coated with the high-temperature superconducting material so that the center conductor is discrete from the dielectric element. The center conductor may have a length which is greater than the length of the dielectric element.

摘要： An electromagnetic device, such as a resonator for a filter, incorporates a high-purity polycrystalline alumina. The device may include a superconducting component, which must be cooled significantly below room temperature. The high-purity polycrystalline alumina may be a dielectric slab in a stripline resonator, or may be used as a stand for holding other components. The high-purity polycrystalline alumina exhibits a very low loss tangent at cryogenic temperatures, and therefore will result in an electromagnetic device with superior performance characteristics.
