Development of high-temperature superconductor cables for high direct current applications by Preuß, Alan Pdf

A design process for HTS DC cables was developed for high current applications. Based on the design process, a 35 kA HTS DC cable demonstrator was developed. The superconducting elements of the demonstrator were manufactured and tested individually at 77 K. Afterwards, the demonstrator cable was assembled and tested at 77 K. The assembled demonstrator successfully reached 35 kA at 77 K and self field conditions.

Technology and readout for scaling up superconducting nanowire single-photon detectors by Knehr, Emanuel Marius Pdf

This work presents three advances to scale SNSPDs from few-pixel devices to large detector arrays: atomic layer deposition for the fabrication of uniform superconducting niobium nitride films of few-nanometer thickness, a frequency-multiplexing scheme to operate multiple detectors with a reduced number of lines, and the integration of SNSPDs with free-form polymer structures to achieve efficient optical coupling onto the active area of the detectors.

AC Losses in High-Temperature Superconductor Tapes and Cables for Power Applications by Godfrin, Aurélien Pdf

This work focuses on two topics. The first is the investigation of producing filaments on copper-stabilized coated conductors, with striations made after or before electroplating the tape. The second topic is the applicability of the striations for reducing the AC losses of cables, in particular the CORC® and RACC cables, which are made with high-temperature superconductor (HTS) striated tapes.

Prospective Life Cycle Assessment of High-Temperature Superconductors for Future Grid Applications by Buchholz, Alexander Pdf

High-temperature superconductors have distinct advantages compared to conventional conductors. Below their critical temperature, superconductors have immeasurably low ohmic losses. To maintain the superconducting state, superconductors require constant cooling. This study aims at identifying the environmental impacts of the application of superconductors in future grid technologies such as superconducting power cables.

Fluorescent thermal imaging method for investigating transient effects in high-temperature superconductor tapes and coils by Gyuráki, Roland Pdf

This work presents the development and application of high-speed fluorescent thermal imaging for quench analysis in high-temperature superconductors (HTS). Using a fluorescent coating, with a temperature-dependent light emission, temperature changes can be calculated over 2D surfaces. The technique uncovered peculiar transient effects in novel HTS tape architectures and also helped to verify and better understand hot spot development in both insulated and non-insulated, HTS–wound pancake coils.

Characterisation of REBCO Roebel cables by Otten, Simon J. Pdf

This work concerns the characterization of high-temperature superconducting REBCO Roebel cables for use in accelerator magnets. The effects of bending, torsion and compressive stress on the cable are investigated. The second part concerns the effect of inter-strand resistance on the cable properties. A two-parameter model is proposed to describe inter-strand connections and predict the effect on AC loss and stability. Additionally, the AC loss and stability are experimentally investigated.
