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.

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.

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.

Design of a superconducting DC wind generator
Author: Liu, Yingzhen
Publisher: KIT Scientific Publishing
ISBN: 373150796X
Category : Technology & Engineering
Languages : en
Pages : 228
Book Description
The trend towards larger power ratings of wind turbines asks for innovations in power generation, which requires lower weight and cost, smaller size, higher efficiency and reliability. Due to high current-carrying capability and no DC losses of superconductors, a superconducting wind generator can have a superior power to weight/volume ratio with high efficiency. The work in the book mainly focuses on the feasibility study and design of a superconducting DC wind generator.

Introduction to Quantum Metrology
Author: Waldemar Nawrocki
Publisher: Springer
ISBN: 3319156691
Category : Technology & Engineering
Languages : en
Pages : 287
Book Description
This book presents the theory of quantum effects used in metrology and results of the author’s own research in the field of quantum electronics. The book provides also quantum measurement standards used in many branches of metrology for electrical quantities, mass, length, time and frequency. This book represents the first comprehensive survey of quantum metrology problems. As a scientific survey, it propagates a new approach to metrology with more emphasis on its connection with physics. This is of importance for the constantly developing technologies and nanotechnologies in particular. Providing a presentation of practical applications of the effects used in quantum metrology for the construction of quantum standards and sensitive electronic components, the book is useful for a wide audience of physicists and metrologists in the broad sense of both terms. In 2014 a new system of units, the so called Quantum SI, is introduced. This book helps to understand and approve the new system to both technology and academic community.
