“…The distance between the two voltage leads on the sample was 50 mm. An I c measurement system with an uncertainty of less than 2% was used in this study (refer [28] for the detailed description of apparatus). Up to 300 A DC current, 10-300 K temperature range, 0-3.5 T magnetic field range and 0 (parallel field)−90°(perpendicular field) field angle range can be achieved by the measurement system.…”

Two categories of high-temperature superconducting (HTS) tapes, the silver-sheathed BSCCO tape (1G HTS tape) and REBCO coated conductor (2G HTS tape), have been commercialized worldwide and widely used in applications. In this study, the 1G HTS tape produced by Sumitomo and 2G HTS tape produced by Superpower were selected for a systematic comparative study in critical current (I c) performances under various temperature and magnetic field conditions. The anisotropy and I c variation patterns of these two types of samples in the temperature range of 25-77 K, magnetic field from 0 to 7 T and field angle from 0 to 90° were compared and analyzed. The results of this study reveal certain comprehensive characteristic features of these two categories of HTS tapes, supplementing some new systematic information to the literature.

Devices made of High Temperature Superconductor (HTS) will suffer AC loss during AC operations, which has unnegligible influence on energy consumption, overall efficiency, cooling cost, and operational stability of the devices. In this study, comparative measurements on 1G and 2G HTS coil samples with an identical structure, geometry, and number of turns were systematically conducted with a calorimetric method at different current values (I rmss) and frequencies (fs). The AC loss characteristics of the HTS samples were analyzed and compared based on the experimental results. The results show that eddy current and coupling play a more dominant role than magnetic hysteresis in the total AC loss of coils made of HTS tapes. The AC loss of both samples increases with I rms and f, but the AC loss is more sensitive to I rms than to f. Under the same conditions, the 1G coil sample has a slightly larger AC loss than the 2G one.

“…(Bi, Pb) 2 Sr 2 Ca 2 Cu 3 O 10+y (Bi-2223) high temperature superconductor (HTSC) has a great potential for a variety of applications such as power transmission cables [1,2], superconducting magnets [3,4], motors [5,6], generators [7,8], transformers [9,10], current limiters [11,12] and current leads [13,14]. This is because the first generation of the Bi-2223 superconducting tapes can carry a sufficiently high transport critical current density, J c , and can be mass produced with a rather low price compared with the second generation of the superconducting tapes [15].…”

Superconducting Bi1.68Pb0.32Sr1.75Ca1.85Cu2.85O10+y (Bi-2223) powders were prepared by a conventional solid-state reaction using hand grinding and wet ball milling. The effects of the ball milling and sintering times on the phase evolution were examined by X-ray diffraction and magnetic susceptibility measurements. Single-phase Bi-2223 powders with a superconducting transition temperature of about 108 K were optimally prepared by wet ball milling for 20 h and sintering at 867 °C for 80 h. Finding these optimal preparation conditions were crucial for mass producing high-quality single-phase Bi-2223 precursor powders with a much lower cost of energy. Furthermore, we found that ball milling led to thinner grains than hand grinding.
