An analytical approach is used to calculate the AC losses of round superconducting cables subjected either to external fields applied perpendicularly to the cable length. Losses for fields applied in one fixed direction but varying sinusoidally in time are compared to losses for applied fields with fixed (with time) amplitudes that rotate around the sample (rotating around an axis parallel to...
A fifteen layer CORC (Cable on Round Conductor) cable, 82 cm long, was tested for stability and normal zone propagation at 77 K in liquid nitrogen bath. The cable had 15 layers, each layer containing 3 tapes, 4 mm wide each. The cable was instrumented with thermocouples, potential taps and wires including as well as excluding its current lug connections. 3 heaters were placed on top of the...
Within the framework to establish standards of test methods for superconducting technical wires, various standards have been published by the International Electrotechnical Commission IEC (standard documents IEC 61788-1 to -20). Following the experience of the successful Round Robin Test RRT for Tensile Test on REBCO Wires at Room Temperature, the effort is extended to Tensile Test on REBCO...
YBCO coated conductors are of interest in a number of possible High Energy Physics applications, like e.g. high field solenoids for muon colliders. A new approach in making YBCO magnets has been suggested recently, where the coils are neither insulated nor epoxied. It is believed that in this approach, the coil is much easier to protect, because one a given zone becomes normal, the lack of...
