Transport and Mechanical Property Evaluation for Cu Stabilized PLD-${\hbox{GdBa}}_{2}{\hbox{Cu}}_{3}{\hbox{O}}_{\rm y}$ Coated Conductor

$I_{\rm c}$– $B$–$T$ Evaluation for High-$T_{\rm c}$ Superconductors in Pressurized/Depressurized Liquid Nitrogen

“…In the case of GdBCO, although the present I c at 77 K and self-field is similar to our previous result [5], which were evaluated in wide range of magnetic field and temperature, infield I c property were improved for both B tape and B ⊥ tape (Fig. 1(c) and (d)).…”

“…Specifications are shown in Table I. A 60-mm long specimens were prepared for each superconductor. The specimen was set on the sample holder, which was described in [4] and [5]. Both ends were mechanically pressed onto the current terminals using copper blocks.…”

High field Ic characterizations of commercial HTS conductors

“…The sample dimensions are slightly different, 30 mm samples for P1 and 35 mm samples for P2. The samples are mounted on GFRP (Glass Fibre Reinforced Plastics) support stage with embedded copper current terminals by mechanical press method [18,19], by pressing the sample on the current leads with copper mounting pieces and screws, without soldering to the current leads. This is a common method to avoid the risk of overheating while soldering and also to facilitate the sample exchange after the measurements.…”

Development of a simplified numerical model for the design of 2G high-temperature superconductors

“…The location of neutral axis position (z n ) can be obtained using the equilibrium equation in the axial direction: (4) which leads to the following expression:…”

“…Experimental studies of the delamination process of HTS conductors 2 nd generation were conducted by (Van der Laan, et al, 2007) and (Gorospe, et al, 2014). Researches on this issue were also conducted by (Jeong, et al, 2012), (Zhang, et al, 2011), (Myazato, et al, 2011), (Nishijima & Kitaguchi, 2012) and (Yanagisawa, et al, 2011), (Van der Laan, et al, 2007) and (Jeong, et al, 2012) showed that it was necessary to investigate the mechanicals properties of HTS materials in order to overcome the mechanical fragility problem. In some applications, the YBCO tape is submitted to bending.…”
