Book excerpt: This book deals with the specific contact between the fourth state of matter, i.e. plasma, and the first state of matter, i.e. a solid wall, in controlled fusion experiments. A comprehensive analysis of the main processes of plasma-surface interaction is given together with an assessment of the most critical questions within the context of general criteria and operation limits. It also contains a survey on other important aspects in nuclear fusion.

Book Synopsis Plasma-Material Interactions in a Controlled Fusion Reactor by : Tetsuo Tanabe

Download or read book Plasma-Material Interactions in a Controlled Fusion Reactor written by Tetsuo Tanabe. This book was released on 2021-03-08. Available in PDF, EPUB and Kindle. Book excerpt: This book is a primer on the interplay between plasma and materials in a fusion reactor, so-called plasma–materials interactions (PMIs), highlighting materials and their influence on plasma through PMI. It aims to demonstrate that a plasma-facing surface (PFS) responds actively to fusion plasma and that the clarifying nature of PFS is indispensable to understanding the influence of PFS on plasma. It describes the modern insight into PMI, namely, relevant feedback to plasma performance from plasma-facing material (PFM) on changes in a material surface by plasma power load by radiation and particles, contrary to a conventional view that unilateral influence from plasma on PFM is dominant in PMI. There are many books and reviews on PMI in the context of plasma physics, that is, how plasma or plasma confinement works in PMI. By contrast, this book features a materials aspect in PMI focusing on changes caused by heat and particle load from plasma: how PFMs are changed by plasma exposure and then, accordingly, how the changed PFM interacts with plasma.

Book Synopsis Atomic and Plasma-material Interaction Processes in Controlled Thermonuclear Fusion by : Ratko K. Janev

Download or read book Atomic and Plasma-material Interaction Processes in Controlled Thermonuclear Fusion written by Ratko K. Janev. This book was released on 1993. Available in PDF, EPUB and Kindle. Book excerpt: Atomic and plasma-material interaction processes play an important role in thermonuclear fusion plasmas and the knowledge of these processes has a significant impact on fusion energy research and development. The present volume provides a comprehensive survey of atomic and plasma-material interaction aspects of controlled thermonuclear fusion. The review articles included in this volume describe the role of atomic and plasma-material interaction processes in the currently most active fusion research areas and emphasize the need for accurate quantitative information on these processes for resolving many outstanding issues in fusion research and reactor design development such as plasma energy balance, particle transport and confinement, impurity control, thermal power and helium exhaust, plasma heating and fuelling, edge plasma physics, development of fusion reactor plasma facing components and plasma diagnostics and modelling.

Book Synopsis Physics of Plasma-Wall Interactions in Controlled Fusion by : D. E. Post

Download or read book Physics of Plasma-Wall Interactions in Controlled Fusion written by D. E. Post. This book was released on 2013-11-21. Available in PDF, EPUB and Kindle. Book excerpt: Controlled thermonuclear fusion is one of the possible candidates for long term energy sources which will be indispensable for our highly technological society. However, the physics and technology of controlled fusion are extremely complex and still require a great deal of research and development before fusion can be a practical energy source. For producing energy via controlled fusion a deuterium-tritium gas has to be heated to temperatures of a few 100 Million °c corres ponding to about 10 keV. For net energy gain, this hot plasma has to be confined at a certain density for a certain time One pro mising scheme to confine such a plasma is the use of i~tense mag netic fields. However, the plasma diffuses out of the confining magnetic surfaces and impinges on the surrounding vessel walls which isolate the plasma from the surrounding air. Because of this plasma wall interaction, particles from the plasma are lost to the walls by implantation and are partially reemitted into the plasma. In addition, wall atoms are released and can enter the plasma. These wall atoms or impurities can deteriorate the plasma performance due to enhanced energy losses through radiation and an increase of the required magnetic pressure or a dilution of the fuel in the plasma. Finally, the impact of the plasma and energy on the wall can modify and deteriorate the thermal and mechanical pro perties of the vessel walls.
