Book Synopsis MultPhysics Modelling towards the Stabilization of PAN Fibers with Microwaves Based on Experimental Data by : Hofele, Julia
Download or read book MultPhysics Modelling towards the Stabilization of PAN Fibers with Microwaves Based on Experimental Data written by Hofele, Julia and published by KIT Scientific Publishing. This book was released on 2024-07-10 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: High energy demand is one reason for high costs of carbon fibers. One option to decrease them is to use microwave heating instead of conventional heating. In this work, steps towards a microwave assisted process during the stabilization phase are presented. In-situ dielectric measurements are performed and a reaction kinetics model is setup in connection to the dielectric loss. This allows to calculate a stabilization degree and fiber temperatures leading to a basic process understanding.
Book Synopsis Automated Mode Recovery and Electronic Stability Control for Wendelstein 7-X Gyrotrons by : Wilde, Fabian
Download or read book Automated Mode Recovery and Electronic Stability Control for Wendelstein 7-X Gyrotrons written by Wilde, Fabian and published by KIT Scientific Publishing. This book was released on 2024-08-07 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetic confinement fusion relies on plasma heating and plasma control using gyrotron oscillators providing at megawatt power levels. The operational reliability decreases when operating at the performance limits due to increasing parasitic mode activity. This work demonstrates for the first time the automated, fast recovery of nominal gyrotron operation during a pulse by exploiting the hysteretic gyrotron behaviour after a mode switch being in use at the Wendelstein 7-X ECRH facility.

Book Synopsis New Type of sub-THz Oscillator and Amplifier Systems Based on Helical-Type Gyro-TWTs by : Marek, Alexander
Download or read book New Type of sub-THz Oscillator and Amplifier Systems Based on Helical-Type Gyro-TWTs written by Marek, Alexander and published by KIT Scientific Publishing. This book was released on 2023-01-26 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work presents the development of a new sub-THz source for the generation of trains of coherent high-power ultra-short pulses at 263 GHz via passive mode-locking of two coupled helical gyro-TWTs. For the first time, it is shown that the operation of such passive mode-locked helical gyro-TWTs in the hard excitation regime is of particular importance to reach the optimal coherency of the generated pulses. This could be of particular interest for some new time-domain DNP-NMR methods.

Book Synopsis Under an Ionized Sky by : Elana Freeland
Download or read book Under an Ionized Sky written by Elana Freeland and published by Feral House. This book was released on 2018-02-13 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is difficult to believe that our planet has been weaponized before our very eyes, but that is exactly what has happened. First, we were seduced by the convenience of a wireless world; then, atmospheric weather experimentation in the guise of carbons “climate change” converted the air we breathe into an antenna. Now, the geo-engineering we’ve been subjected to for two decades is being normalized as the “Star Wars” Space Fence rises around and within us. Is this the Space Age we were promised?

Book Synopsis Bringing Fusion to the U.S. Grid by : National Academies of Sciences Engineering and Medicine
Download or read book Bringing Fusion to the U.S. Grid written by National Academies of Sciences Engineering and Medicine and published by . This book was released on 2021-11-17 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fusion energy offers the prospect of addressing the nation's energy needs and contributing to the transition to a low-carbon emission electrical generation infrastructure. Technology and research results from U.S. investments in the major fusion burning plasma experiment known as ITER, coupled with a strong foundation of research funded by the Department of Energy (DOE), position the United States to begin planning for its first fusion pilot plant. Strong interest from the private sector is an additional motivating factor, as the process of decarbonizing and modernizing the nation's electric infrastructure accelerates and companies seek to lead the way. At the request of DOE, Bringing Fusion to the U.S. Grid builds upon the work of the 2019 report Final Report of the Committee on a Strategic Plan for U.S. Burning Plasma Research to identify the key goals and innovations - independent of confinement concept - that are needed to support the development of a U.S. fusion pilot plant that can serve as a model for producing electricity at the lowest possible capital cost.

Download or read book Fusion Neutronics written by Yican Wu and published by Springer. This book was released on 2017-08-16 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a systematic and comprehensive introduction to fusion neutronics, covering all key topics from the fundamental theories and methodologies, as well as a wide range of fusion system designs and experiments. It is the first-ever book focusing on the subject of fusion neutronics research. Compared with other nuclear devices such as fission reactors and accelerators, fusion systems are normally characterized by their complex geometry and nuclear physics, which entail new challenges for neutronics such as complicated modeling, deep penetration, low simulation efficiency, multi-physics coupling, etc. The book focuses on the neutronic characteristics of fusion systems and introduces a series of theories and methodologies that were developed to address the challenges of fusion neutronics. Further, it introduces readers to the unique principles and procedures of neutronics design, experimental methodologies and methodologies for fusion systems. The book not only highlights the latest advances and trends in the field, but also draws on the experiences and skills collected in the author’s more than 40 years of research. To make it more accessible and enhance its practical value, various representative examples are included to illustrate the application and efficiency of the methods, designs and experimental techniques discussed.
