摘要： This invention describes a means by which lasers and laser beam controllers mounted on moving vehicles or other unstable platforms can be isolated from vibrations. By magnetically levitating the entire laser or just the beam controller hardware, targeting efficiency can be vastly improved. Superconducting levitation and control coils can be used to reduce added power losses. Cryogenic power conversion systems can be employed to drive the levitation system. The laser could also be cryogenically cooled, depending on the type of laser employed.

摘要： This invention describes a means by which performance characteristics of capacitors can be improved. This is achieved by reducing the temperature, preferably but not exclusively to cryogenic temperatures below 100 K. This is based on the observation that the dielectric strength, dielectric losses and plate losses in many capacitors, such as film capacitors, improve as the temperature is decreased. A cryogenic capacitor bank is also described, which exhibits energy densities up to four times those of conventional, room-temperature capacitor banks. Cryogenic capacitors can be combined with cryogenically operated semiconductors or with superconductors in such a way as to reduce the size, weight, and losses of a complete system.

摘要： A magnetic suspension system and a procedure for operating the system employ a superconducting magnet having a lift coil assembly for developing a magnetic field to interact with the magnetic field of an object to be supported about the superconducting magnet. Smaller and larger magnet coils are provided in the superconducting magnet with counter rotating flow of current to introduce a depression in a potential energy surface above the superconducting magnet, this allowing the object to seek a height at the depression for stably locating the object. The system and methodology employs a set of control coils which are energized to orient and to translate the object to maintain a desired position and orientation. Pairs of the control coils are energized to produce a tilting of the object, as in roll or pitch, or a displacement of the object relative to the vertical axis.

摘要： Switching losses and conduction losses are isolated by networks which are partially cryogenic and partially at room temperature. Switching losses are independent of temperature. Advantageously the switching losses are taken in a snubber network at room temperature and conduction losses are incurred at cryogenic temperatures, where majority carrier devices like MOSFETs operate with ultra low on-state resistance and corresponding low conduction losses. Low loss leads carry current efficiently from the cryogenic environment to room temperature without adversely affecting refrigeration. Switch and snubber network may both operate cryogenically.

摘要： In a high field superconducting magnet device, e.g., for NMR, a conventional low temperature superconducting solenoid type magnet is combined with an inserted superconducting magnet, which is fabricated from high temperature superconducting materials having very high critical currents. Both magnets operate with stability at the same low temperature in persistent modes after operating conditions are achieved. The flux field and superconducting currents in the inserted superconducting magnet are generated by flux trapping when the field of the low temperature superconducting solenoid type magnet is reduced. The field of the hybrid magnet assembly is the resultant of the respective fields of the two magnets.

摘要： A bi-directional power converter for cryogenic operation based on a bi-directional cryo-MOSFET switch. Cryogenic power electronics lends itself easily to bi-directional topologies, and brings higher efficiencies, further reductions in switching speed, higher-frequency operation, reduction in size and weight of associated transformers and inductors, and reductions in overall size and weight. In addition, cryogenic power electronics operating around liquid nitrogen temperatures is easily integrated with superconducting motors, motor drives, and transformers, all of which can reduce size and weight of shipboard power systems, allowing for greater payload.

摘要： An electrical switching topology for a hybrid switch provides extremely low losses in both cryogenic and non-cryogenic electronic systems. In this switch having switch modules connected in parallel, switching losses in a first module are separated from conduction losses in the parallel-connected second module. The conduction losses are then further reduced by cryogenically cooling the second module. Since the switching losses of the first module can be absorbed outside a cryogenic container, the switching losses do not add to the cryogenic heat load. In other applications, the switching module operates at lower temperatures to provide higher switching speeds and reduces switching heat generation.
