superconductivity ieee paper

with computed values, Superconducting Fault Current Limiter (SFCL) is an attractive appliance for modern electrical power system. Furthermore, we took the opportunity to test a new magnetic quench inducing system. Grade => Non-Member, Eligibility Criteria Failure. Using an ANSYS code the effect of the eddy currents on build-up of the gradient fields is firstly investigated. work done is presented. By adopting vertically stacked SIS junctions (VSJs), which have an equivalent geometric capacitance inversely proportional to the junction number, it becomes feasible to increase the junction tuning inductance. IEEE Transactions on Applied Superconductivity, 2007 This paper proposes an effective parametric design for high temperature superconducting (HTS) synchronous motors with 3D equivalent magnetic circuit network (EMCN) method. In addition, the IF-output-power stability and aging effect of fabricated NbN SIS junctions are investigated. We found that the height of the current steps depended on the loss of the resonator. interruption of power could lead to a long and costly shutdown. In this paper, we report on the design, fabrication, and characterization of twin Nb/Al-AlOx/Nb/Al-AlOx/Nb VSJs for the 500-GHz frequency band. Double sideband (DSB) receiver noise temperatures of 920 K at 1.6 THz and 1630 K at 2.5 THz have been obtained at 4.2 K without corrections. rotational properties of the rotor are discussed. In the first year of this 3-year program, we have completed magnetic analysis and design of both coils. In order to improve SNR, a surface coil that is made of a Bi-2223 tape is fabricated for a 0.3T permanent MRI system. In Phase II experiment of a large helical device (LHD) of the National Institute for Fusion Science (NIFS), the helical coils are planned to be operated at 1.8 K by employing pressurized superfluid cooling to raise the magnetic field up to 4 T using a current of 17.3 kA. A Bi-2223 surface RF coil was developed for a 0.3T permanent MRI system to achieve better signal-to-noise ratio (SNR) of images. A thermal model of the overall cryogenic system was calibrated from those measurements. commercialized μ-SMES concepts are based on NbTi technology. Appl. The topology and control strategy are illustrated in this paper. The lower substrate temperature seems to be favorable for the better biaxial orientation of the NdBa₂Cu₃O₇ grains; the film deposited at 650°C had an excellent biaxial crystal orientation, while on the textured Ag tape heated at 720°C, NdBa₂Cu₃O ₇ phase grew in two orientations, 45° apart, Direct transport critical current density ( J _c) IEEE Council on Superconductivity (IEEE CSC) The purpose of the Council is to advance and coordinate work in the fi eld of superconductivity conducted throughout the IEEE, and as such is primarily technical and educational in character. J _c( H ) showed very different behavior for The solenoid will be tested in the SULTAN To reduce the effect of induced eddy currents in the pole plates by pulsed gradient fields, a couple of specially-designed steel sheets were fixed on the pole plates. It is important to develop a 20 kA-class current feedthrough into the 1.8 K region with high current capacity and low heat leakage in the maximum leakage magnetic field of 1 T. The YBCO bulk conductors of 20 mm in width, 140 mm in length and 10 mm in thickness were assembled into a prototype 1.8 K current feedthrough. We also highlight recent and technical results of importance, including information on useful tools, etc. In particular, the The magic-angle-spinning magnet comprises a z-axis 0.866-T solenoid and an x-axis 1.225-T dipole, each to be wound with NbTi wire and operated at 4.2 K in persistent mode. films with field applied normal to the film surface, the pinning Some peculiar features of deformation of non-uniform composites containing the nanostructured elements have been presented.
