• ### Magnetizing performance evaluation of HTS bulk magnet using a 12 K refrigerator with high cooling capacity

Publication Year: 2018, Page(s): 1
| | PDF (1373 KB)

We study a high magnetic field generation using HTS bulk magnets activated by pulsed-field magnetization (PFM) with the goal of their industrial application. In our previous study, a single-stage GM-type refrigerator and a dual-stage GM-type refrigerator with air-cooled-type compressor and a Stirling refrigerator were used for cooling an HTS bulk aiming at simplifying the bulk magnet system. Now, ... View full abstract»

• ### Electrical Characteristics of Long Josephson Junctions Based on Tungsten Nanorods as Weak Links: Effect of Random Critical-Current Distributions

Publication Year: 2018, Page(s): 1
| | PDF (481 KB)

The numerical model of long Josephson junctions with Gaussian spread of critical currents have been developed. The model allowed calculating IV-characteristics and power of emission of long junctions. Zero-field steps in IV-characteristics in the hysteretic region were found. When spread of critical currents was comparable with the value of the averaged critical current, particularities correspond... View full abstract»

• ### Flux pinning mechanisms and competition between δl and δT_c pinning in polycrystalline nano-alumina doped YBa2Cu3O7-y

Publication Year: 2018, Page(s): 1
| | PDF (1285 KB)

Flux-pinning mechanisms of Al2O3 doped YBa2Cu3O7-y (Y-123) has been investigated by electrical and magnetic measurements. Using the Ambegaokar and Halperin (AH) model applied to magnetoresistivity$\rho$(T,H), we calculated the critical current density in the grain boundaries at zero temperature. The field dependence of the critical density, J_c (B), was analyzed withi... View full abstract»

• ### Mechanical Properties of Superconducting (Gd,Y)BaCuO Large Single-Grain Material Fabricated by RE Compositional Gradient Technique

Publication Year: 2018, Page(s): 1
| | PDF (541 KB)

In order to investigate the mechanical properties of a (Gd,Y)BaCuO large single-grain bulk material, bending tests were carried out at room temperature for the specimens cut from the bulk material. A precursor which consisted of three regions with different Gd and Y contents was used for the fabrication of the large single-grain bulk material in order to overcome the un-desirable nucleation apart ...

• ### Optimization of high-energy ball milling time for$Fe_{1.1}Se_{0.5}Te_{0.5}$polycrystalline superconductors

Publication Year: 2018, Page(s): 1
| | PDF (2412 KB)

The$Fe_{1.1}Se_{0.5}Te_{0.5}$polycrystalline superconductors were prepared by a high energy ball milling (HEBM) technique. The different ball milling time of 0, 2, 4, 6 and 8 h was adopted to optimize this technique. The influences of ball milling time on the phase distributions of milled powders and sintered bulks, the morphology of ball milled powders and supercondu... View full abstract»

• ### Calculation Method Study of HTS Coils' Critical Current

Publication Year: 2018, Page(s): 1
| | PDF (1493 KB)

A method to calculate second-generation (2G) high temperature superconducting (HTS) coils' critical current is presented. Critical current and n value of HTS tapes measured under different magnet field are used for calculation of the coil. The distribution of HTS coils' magnetic field intensity, current density and electric field intensity is calculated with COMSOL 2D based on H formulation. A Par... View full abstract»

• ### High-Temperature Superconducting Periodic Transmission Line

Publication Year: 2018, Page(s): 1
| | PDF (1171 KB)

In this paper, a high-temperature superconducting (HTS) transmission line periodically loaded with small insulator gaps is studied in order to investigate its microwave characteristics. We calculate dispersion and impedance equations for both cases of infinite and finite periodic structures. For the infinitely long periodic structure, the method of analysis is based on the ABCD matrix representati... View full abstract»

• ### The Present Status and Progress of the CHMFL 40 T Hybrid Magnet

Publication Year: 2018, Page(s): 1
| | PDF (177 KB)

The development of new high magnetic field facilities in the Chinese High Magnet Field Laboratory (CHMFL) will soon be completed according to the present situation. For the construction of the 40 T hybrid magnet, which will be the highest magnetic field facility in China, great progress has been achieved so far, for example, the engineering design of the resistive insert composed of six Florida-Bi...
