Book Description
Nuclear fusion is a key technology to satisfy the basic demand for electric energy sustainably. The official EUROfusion schedule foresees a first industrial DEMOnstration Fusion Power Plant for 2050. In this work several high temperature superconductor sub-size cables are investigated for their applicability in large scale DEMO toroidal field coils. Main focus lies on the electromechanical stability under the influence of high Lorentz forces at peak magnetic fields of up to 12 T.

AC Losses in High-Temperature Superconductor Tapes and Cables for Power Applications
Author: Godfrin, Aurélien
Publisher: KIT Scientific Publishing
ISBN: 3731510960
Category : Technology & Engineering
Languages : en
Pages : 146
Book Description
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.

Category : Technology & Engineering
Languages : en
Pages : 194
Book Description
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.

Characterisation of REBCO Roebel cables
Author: Otten, Simon J.
Publisher: KIT Scientific Publishing
ISBN: 3731509040
Category : Technology & Engineering
Languages : en
Pages : 208
Book Description
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.

Fluorescent thermal imaging method for investigating transient effects in high-temperature superconductor tapes and coils
Author: Gyuráki, Roland
Publisher: KIT Scientific Publishing
ISBN: 3731510642
Category : Science
Languages : en
Pages : 194
Book Description
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.

Magnetization of High Temperature Superconducting Trapped-Field Magnets
Author: Zou, Shengnan
Publisher: KIT Scientific Publishing
ISBN: 3731507153
Category : Technology (General)
Languages : en
Pages : 174
Book Description
High temperature superconducting (HTS) bulks and stacks of coated conductors can be magnetized to become trapped-field magnets that provide much stronger magnetic fields than those reachable with conventional permanent magnets. This work investigates the flux dynamics during the magnetization of HTS trapped-field magnets and proposes possible strategies to improve the trapped field produced by the pulsed field magnetization method that is promising for practical applications.

Prospective Life Cycle Assessment of High-Temperature Superconductors for Future Grid Applications
Author: Buchholz, Alexander
Publisher: KIT Scientific Publishing
ISBN: 3731511940
Category : Technology & Engineering
Languages : en
Pages : 246
Book Description
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.

Electrical-field sensitive YBa₂Cu₃O₇₋ₓ detectors for real-time monitoring of picosecond THz pulses
Author: Raasch, Juliane
Publisher: KIT Scientific Publishing
ISBN: 3731507862
Category : Technology (General)
Languages : en
Pages : 226
Book Description
This work investigates the capability of the high-temperature superconductor YBCO to sense the evolution of the electrical field of THz pulses. A deposition process for ten unit-cell thin films and a sub-μm patterning process were developed to enable high sensitivities. The detector response to THz exctiations and its electrical-field sensitivity were studied. This unique characteristic allows for the investigation of instabilities of the THz radiation emitted from synchrotron storage rings.
