Book Description
For the analysis and optimization of the picosecond pulsed terahertz radiation generated by electron storage rings or other pulsed sources, ultra-fast detectors are required which are able to resolve picosecond dynamic processes directly in the time domain. In this book, a new direct terahertz detector technology based on the high-temperature superconductor YBa2Cu3O7-x has been developed which opens new routes in the analysis of picosecond time-domain processes with a wide dynamic range.

Electrical-field sensitive YBa₂Cu₃O₇₋ₓ detectors for real-time monitoring of picosecond THz pulses
Author: Raasch, Juliane

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.

Development of high-temperature superconductor cables for high direct current applications
Author: Preuß, Alan
Publisher: KIT Scientific Publishing
ISBN: 3731510413
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.

Improving the Spectral Bandwidth of Superconducting Nanowire Single-Photon Detectors (SNSPDs)
Author: Charaev, Ilya
Publisher: KIT Scientific Publishing
ISBN: 3731507455
Category : Nanowires
Languages : en
Pages : 176
Book Description
This work presents a comprehensive investigation of the influence of geometry-dependent factors on performance metrics of superconducting single-photon detectors. With fundamental knowledge, main investigations are focused to extend the spectral bandwidth and to enhance the detection efficiency, especially in infrared range. The developed technology of single-spiral detectors and unconventional electron-beam lithography allows to improve the performance of superconducting detectors.

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.

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.
