We present a heuristic for the automated extraction of state machine representations of rapid single-flux-quantum (RSFQ) digital logic circuits given a circuit SPICE representation. Furthermore, this heuristic uses the SPICE netlist to extract timing characteristics for the creation of a hardware description language (HDL) implementation of the circuit. This facilitates RSFQ logic design at an HDL... View full abstract»

We report on the microwave properties of coaxial cavities built by using bulk MgB2superconductor prepared by reactive liquid Mg infiltration technology. We have assembled a homogeneous cavity by using an outer MgB2cylinder and an inner MgB2rod and a hybrid cavity by using an outer copper cylinder and the same MgB2rod as inner conductor. By the analysis o... View full abstract»

An Evershed type of superconducting magnetic bearing is designed and fabricated. An alternative torque mechanism is proposed to drive the rotor of the designed bearing. The design consideration for the rotor consists of a permanent magnet with 7.5-kg mass and its force interaction with the superconductor defined in terms of a semi-analytical frozen image model. The driving mechanism is based on ed... View full abstract»

A 1.5-T whole-body magnetic resonance imaging (MRI) magnet was designed and manufactured at the Institute of High Energy Physics, Chinese Academy of Sciences, Beijing, China. The designed field inhomogeneity is less than 50 parts per million peak-to-peak in a sphere with a diameter of 50 cm. Unfortunately, during the process, there are many different manufacturing errors that can generate field in... View full abstract»

The design of a cable-in-conduit conductor (CICC) is a very complicated engineering process. In order to simplify the design for CICCs, a simulation design method is presented in this paper with the relationship between the operating current and the critical current, and the extreme case that the Stekly parameter is equal to 1. In addition, a novel optimization model for CICC design is proposed fo... View full abstract»

Rim-driven thrusters have received much attention concerning the potential benefits in vibration and hydrodynamic characteristics, which are of great importance in marine transportation systems. In this sense, the rim-driven permanent magnet, brushless dc, and induction motors have been recently suggested to be employed as marine propulsion motors. On the other hand, high-temperature superconducti... View full abstract»

| | PDF (1623 KB) | HTML

Compact and lightweight direct-drive generators in large rating are desired for offshore wind farm applications. A key goal for such generators is that they be manufactured and tested in a factory and shipped to the site as fully assembled units. A possible approach to achieving this goal is to construct both rotor and stator windings with high-temperature superconducting (HTS) materials. The magn... View full abstract»

• ### Experimental Studies of the Resistive Superconducting Fault Current Limiter Based on Double-Sided YBCO Thin Films

Publication Year: 2014, Article Sequence Number: 5600905
| | PDF (1137 KB) | HTML

This paper proposes a new thin-film superconducting fault current limiter (SFCL) that is composed of double-sided thin films to improve the compactness of SFCL systems. In the double-sided design with assembling SFCL units on a wafer comes a possibility of freeing from the negative effect of magnetic flux penetration at the film edges by orienting current paths and taking advantage of thermal inte...

We injected a dc near-critical current through a yttrium-barium-copper oxide (YBCO) superconductor microbridge in the presence of a high pulsed ac magnetic field (10 MT/s up to 20 T) parallel to the dc current flow - the so-called Lorentz force free configuration. A transmitted RF signal probed the YBCO mixed state that followed the ac magnetic field cycles. Based on inflection points on this modu... View full abstract»

| | PDF (450 KB) | HTML

All superconducting radio-frequency (RF) cavities are currently manufactured using high-purity Nb sheet, and although properties of the best cavities are excellent, there is still considerable variability, and we examine here the chemistry at the Nb grain boundaries (GBs), which may be a source of cavity performance degradation. Some oxidization at GBs in niobium cavities may be inevitable during ... View full abstract»

We have developed a fluorine-free metal-organic decomposition method using acrylic acid as the solvent for the synthesis of GdBCO superconducting thin films. Commonly used propionic acid was also used to make a comparison with acrylic acid. Acrylic acid was found to be polymerized during drying, resulting in high thermal stability of the precursor solution. Due to the elevated decomposition temper... View full abstract»

Numerical modeling of superconductors is widely recognized as a powerful tool for interpreting experimental results, understanding physical mechanisms, and predicting the performance of high-temperature-superconductor (HTS) tapes, wires, and devices. This is particularly true for ac loss calculation since a sufficiently low ac loss value is imperative to make these materials attractive for commerc... View full abstract»

Power losses are an important phenomenon in type-2 superconductors. Precise evaluation of power losses in superconducting coils is crucial for designing novel machines such as superconducting motors or generators. Although ac losses are relatively easy to measure with electrical methods, it is more difficult to measure power losses in the dc mode, which is induced by varying external magnetic fiel...

Field penetration and ac loss of high-temperature superconductor (HTS) windings wound by parallel-connected (PC) tapes are simulated and calculated. The simulation is given to a winding with six tapes, which are connected to produce either n = 1, 2, 3, or 6 PC current turns. The PC turns are basically organized as two main types according to whether the turn end is soldered or not. The soldering s... View full abstract»
