    The mechanical properties and the critical current were studied in three commercial multifilamentary Bi2Sr2Ca2Cu3O10+x/Ag tapes subjected to monotonic and fatigue tension at 77 K in the longitudinal direction. It was found that transport properties were not compromised under monotonic tension if the maximum tensile stress remained below the co... View full abstract»

    Reinforcing multifilamentary Bi2Sr2Ca2Cu3Oy (2223-BSCCO) requires careful evaluation of magnetic losses and, in general, of the quantities related to the hysteresis loop (e.g., coercive field and residual magnetization). In this paper, the results of magnetic quantity measurements performed on superconductive tapes reinforced by both AISI 304 and AISI 31... View full abstract»

    The high-temperature superconductor (HTS) development is presently intensive, and one can expect that HTSs will be used in different electric devices in the future. In some of these devices, e.g., a magnetostrictive actuator, the conductor will be exposed to both ac and dc transport currents and external magnetic fields. One of the most important parameters in the design of electric devices is the... View full abstract»

    The magneto-optical imaging (MOI) technique is widely employed to characterize the magnetic properties of superconductors and other magnetic materials because it can easily show the variation of flux density over a plane with relatively high resolution. In this paper, flux profiles visualized by the MOI technique will be presented for different experimental conditions. The sample investigated is a... View full abstract»

  • Magnetic-shield-type fault current limiter equivalent circuit

    In order to investigate how a superconducting fault current limiter (SFCL) can enhance the performance of a power system, an accurate circuit model of the device needs to be introduced in power system simulators. In this paper, we present a finite-element numerical model to calculate the time evolution of the voltage across a magnetic-shield-type SFCL, when it is connected to an external circuit. ...

    We introduce and analyze an optoelectronic mixer (OEM) based on the kinetic inductive photoresponse in high-temperature superconducting (HTS) films. This device combines photodetection and optoelectronic mixing functions through a nonlinear change in the kinetic inductance of the HTS film when it is irradiated by an optically modulated microwave signal. A comprehensive theoretical analysis is pres... View full abstract»

  • An FDTD model for calculation of gradient-induced eddy currents in MRI system

    In most magnetic resonance imaging (MRI) systems, pulsed magnetic gradient fields induce eddy currents in the conducting structures of the superconducting magnet. The eddy currents induced in structures within the cryostat are particularly problematic as they are characterized by long time constants by virtue of the low resistivity of the conductors. This paper presents a three-dimensional (3-D) f... View full abstract»

    Design, parameters, and application areas of a superconducting fault current limiter (FCL) are analyzed on the basis of the requirements of power systems. The comparison of resistive and inductive designs is carried out. An example of the effective application of FCLs in distribution substations is considered and the gain from the FCL installation is discussed. It is shown that an FCL not only lim...

    This paper examines the "magnetic potential well" effect by the example of two ring-shaped superconductive coils. This effect allows us to create a noncontact magnetic suspension of one coil and to define its movements by measuring the current in the stationary coil. It is shown that the system of these two coils is unstable with respect to the tilt angle. The new construction of the levitated coi... View full abstract»

    Designs of magnetic resonance imaging (MRI) main magnets obtained from both a functional method and a genetic algorithm method have been compared. While most features in the two approaches are similar, there are several important differences. The functional method leads to fewer coil bundles and a reduced total current, i.e., total ampere turns, (e.g., 6-8 MA) that can be as much as 70% of the tot... View full abstract»

    An investigation on short-term and long-term mechanical characteristics of Bi2Sr2Ca2Cu3Oy reinforced tapes is presented in this paper. Results of critical current measurements obtained after bending, as well as during application of tensile stress and strain, are shown. Data are processed to provide a threshold model for the bending test, acco... View full abstract»
