Experimental Verification of the Temperature and Strain Dependence of the Critical Properties in Nb3Sn Wires
The critical current density in NbJSn conductors is described with an improved scaling formula for the temperature, magnetic field and strain dependence. In an earlier study it is concluded that the largest uncertainties in this description arise from the temperature dependence that is described with various slightly different empirical relations. For the optimization of the numerical codes, us...
متن کاملthe effect of using critical discourse analytical tools on the improvement of the learners level of critical thinking in reading comprehension
?it is of utmost priority for an experienced teacher to train the mind of the students, and enable them to think critically and correctly. the most important question here is that how to develop such a crucial ability? this study examines a new way to the development of critical thinking utilizing critical discourse analytical tools. to attain this goal, two classes of senior english la...
Performance Boost in Industrial Multifilamentary Nb3Sn Wires due to Radiation Induced Pinning Centers
We report non-Cu critical current densities of 4. 09 ⋅ 10(9) A/m(2) at 12 T and 2.27 ⋅ 10(9) A/m(2) at 15 T obtained from transport measurements on a Ti-alloyed RRP Nb3Sn wire after irradiation to a fast neutron fluence of 8.9 ⋅ 10(21) m(-2). These values are to our knowledge unprecedented in multifilamentary Nb3Sn, and they correspond to a Jc enhancement of approximately 60% relative to the un...
متن کاملTHE INFLUENCE OF TRANSVERSE, COMPRESSIVE STRESS ON THE CRITICAL CURRENT OF MULTIFILAMENTARY Nb,Sn AND NbTi WIRES
In order to investigate the critical current of multifilamentary wires as a function of the applied field and transverse, compressive stress, a special experimental arrangement has been developed. In this arrangement, the repulsive Lorentz force generated by a set of magnets is used, to press a sample between two parallel surfaces. From the first experimental results on a multifilamentary NbTi ...
متن کاملBending-Strain Test Results of ITER Nb3Sn Wires and Preliminary Model Analysis
Bending effects on Nb 3 Sn wires have been investigated to understand the critical current degradation of large Nb 3 Sn superconducting cables, such as the ITER conductors. Characterizations of the critical currents of various Nb 3 Sn wires were carried out by a previously reported pure-bending strand test device using the 20 T, 195 mm Bitter magnet at the National High Magnetic Field Laborator...
