TL;DR: In this paper, the magnetization loss of a multifilamentary YBCO coated conductor was studied experimentally, where the sample was accomplished by laser ablation. And the measured magnetization losses of the 100mm striated conductor was less than 9% of the measured loss of the non-striated conductor at f = 11.3

TL;DR: In this article, a mechanically rotating superconducting flux pump was used to excite an HTS double pancake coil at 77 K. This flux pump is found to possess an effective internal resistance, Reff, which varies linearly with frequency, and is two orders of magnitude larger than the measured series resistance of the soldered contacts within the circuit.

TL;DR: In this article, a brushless HTS-PM exciter is proposed to inject a superconducting DC current into the rotor coil circuit, which can significantly alter the thermal load upon the cryogenic system by removing the need for thermally inefficient normalconducting current leads.

TL;DR: In this article, the effect of varying the size of the flux gap between the rotor magnets and coated conductor stator from 1 to 7.5 mm was investigated and it was shown that the performance of an experimental mechanically rotating HTS flux pump ceases to maintain a measurable output at flux gaps above 7.

TL;DR: In this article, a high-Tcsuperconducting (HTS) homopolar dynamo which outputs a DC open-circuit voltage when the stator is in the superconducting state, but behaves as a conventional AC alternator when in the normal state is observed, which is attributed to screening currents in the HTS stator wire.
