Fundamenski W. Power Exhaust in Fusion Plasmas
CAMBRIDGE UNIVERSITY PRESS, 2010, - 426 p. (Анг. язык)

Power exhaust, by which we mean the safe removal of power from a buing plasma, is an essential requirement for the successful operation of any fusion reactor. Specifically, plasma thermal energy must be conveyed across the first wall without undue damage to plasma facing components (divertor and limiter tiles) by heat load related plasma–surface interactions (ablation, melting, erosion). Unlike other ‘technological’ problems related to fusion reactor design, e.g. tritium retention in plasma facing materials, neutron damage to structural components or non-inductive current drive, power exhaust is intimately linked to plasma confinement and thus a perennial conce for any fusion reactor. While only a minor issue in existing tokamaks, it will be critical for ITER (the next step plasma-buing experiment) and even more so for DEMO (the demonstration fusion power plant). Even non-buing, superconducting machines, such as EAST, KSTAR, JT60-SA,
W7-X, etc. will be forced to tackle this problem due to their long pulse capabilities. This monograph is an attempt to draw a unified and up-to-date picture of power exhaust in fusion plasmas, focusing primarily on the leading tokamak concept. Emphasis is placed on rigorous theoretical development, supplemented by numerical simulations when appropriate, which are then employed to explain and model a range of experimental observations. The objective is not just to provide the reader with a reliable map of the conquered territory and a guided tour over its many hills and valleys,1 but also to supply him or her with the tools necessary to embark on independent, and hopefully fruitful, joueys into the uncharted regions, the white spaces on the map, la terra incognita. In this respect, the book is aimed both at graduate students of magnetically confined plasmas and at researchers already working in the field wishing to develop a deeper understanding of plasma exhaust physics – a quickly emerging area of fusion research.

Springer-Verlag London, 2008, 161 pages The problem of confining a plasma, with sufficiently high density and temperature, is of crucial importance if nuclear fusion is to be made usable as a form of power generation. Tokamaks – devices with a toroidal geometry – are among the most popular candidates by which such confinement can be achieved. A tokamak separates a plasma from its surroundings by means of a magnetic field generated by several co...

Springer-Verlag Berlin, 2005, 461 pages It became clear in the early days of fusion research that the effects of the containment vessel (erosion of "impurities") degrade the overall fusion plasma performance. Progress in controlled nuclear fusion research over the last decade has led to magnetically confined plasmas that, in turn, are sufficiently powerful to damage the vessel structures over its lifetime. This book reviews current understandin...

Springer, 2010, -398p. This book is an outgrowth of courses in plasma physics which I have taught at Kiel University for many years. During this time I have tried to convince my students that plasmas as different as gas dicharges, fusion plasmas and space plasmas can be described in a unified way by simple models. The challenge in teaching plasma physics is its apparent complexity. The wealth of plasma phenomena found in so diverse fields makes i...
