Superconducting On-chip Fourier Transform Spectrometer [PDF]

open access: yesJournal of Low Temperature Physics, 2020
Kinetic inductance in thin film superconductors has been used as the basis for low-temperature, low-noise photon detectors. In particular thin films such as NbTiN, TiN, NbN, the kinetic inductance effect is strongly non-linear in the applied current, which can be utilized to realize novel devices.

Superconducting traction transformer

open access: yesTransformers Magazine, 2021
An ongoing project to develop HTS traction transformers for the Chinese Fuxing high-speed train is demonstrating that the high-power density can be reached using high-temperature superconductors (HTS). The findings are spectacular: the existing 6.5 MVA traction transformers can be replaced with drop-in superconducting transformers, achieving targets of

SUPERCONDUCTING TRANSFORMER FOR SUPERCONDUCTING CABLE TESTS IN A MAGNETIC FIELD [PDF]

open access: yesAIP Conference Proceedings, 2010
To meet the need in the applied superconductivity community of a cable test facility at high magnetic fields, a superconducting current transformer that was designed to deliver about 40 kA of DC current in Rutherford cables was designed and fabricated for operation in a 14 T/16 T solenoid with 77 mm bore. The existing infrastructure of the Short Sample

Quench protection of superconducting transformers.

open access: yesTEION KOGAKU (Journal of Cryogenics and Superconductivity Society of Japan), 1990
Methods to protect superconducting transformers from premature quench due to local disturbances and excess current at accidental short-circuit were studied with regard to structure of the conductor and construction of the transformer. Average variations in temperature of the winding were calculated by a heat balance equation under the conditions both ...
