Book excerpt: The tokamak is modeled as typically 100 mutually-coupled toroidal circuits. The self and mutual inductances and the currents and voltages are calculated. Using the calculated currents, the poloidal magnetic field and the electromagnetic forces as functions of space and time are calculated. The major conclusion of the analysis is that the torus sectors should be electrically connected to each other near the plasma. Such connections reduce the structural loads, eliminate arcing, and reduce the induced potentials in the poloidal field coils.

Available in PDF, EPUB and Kindle. Book excerpt: To model the consequences of a plasma disruption in a tokamak one must combine a code that computes the detailed MHD behavior of the plasma with one that treats the three-dimensional features of the conducting toroidal components around the plasma. The NET (Next European Torus) Team have undertaken a treatment of electromagnetic effects from plasma disruptions using both open loop and closed loop integration of codes. In America, workers at Oak Ridge National Laboratory, Idaho National Engineering Laboratory, and Argonne National Laboratory have looked at plasma disruption effects on the ITER blanket using the codes TSC and EDDYNET. Results show how the forces on a blanket segment depend on the number and size of the segments and on the gap between them. 9 refs., 4 figs., 1 tab.

Download or read book The Physics of Plasmas written by T. J. M. Boyd and published by Cambridge University Press. This book was released on 2003-01-23 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Physics of Plasmas provides a comprehensive introduction to the subject, illustrating the basic theory with examples drawn from fusion, space and astrophysical plasmas. A particular strength of the book is its discussion of the various models used to describe plasma physics and the relationships between them. These include particle orbit theory, fluid equations, ideal and resistive magnetohydrodynamics, wave equations and kinetic theory. The reader will gain a firm grounding in the fundamentals, and develop this into an understanding of some of the more specialised topics. Throughout the text, there is an emphasis on the physical interpretation of plasma phenomena. Exercises are provided throughout. Advanced undergraduate and graduate students of physics, applied mathematics, astronomy and engineering will find a clear but rigorous explanation of the fundamental properties of plasmas with minimal mathematical formality. This book will also appeal to research physicists, nuclear and electrical engineers.

Book Synopsis Tokamak Disruptions by : Adrian Kristopher Fontanilla
Download or read book Tokamak Disruptions written by Adrian Kristopher Fontanilla and published by . This book was released on 2019 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plasma disruptions are a catastrophic loss of confinement that ultimately concludes with the release of the thermal and magnetic energy stored in the vessel containing the plasma. The threat of disruptions therefore factor into the development of fusion-grade tokamak reactors such as ITER. This work discusses the deleterious effects of disruption, particularly runaway electrons. Tokamaks are especially susceptible to runaway electrons because of their highly inductive nature. The lifetime of seed runaways are calculated and the likelihood for them to exponentiate is discussed. Strategies for alleviating the danger posed by disruptions are considered. The basic strategy, assuming a disruption is imminent, is to preemptively cool the plasma. ITER currently plans on deploying impurity pellets to safely radiate away the energy, so investigations of pellet heating and ablation are conducted
Book Synopsis Magnetohydrodynamic Stability of Tokamaks by : Hartmut Zohm
Download or read book Magnetohydrodynamic Stability of Tokamaks written by Hartmut Zohm and published by John Wiley & Sons. This book was released on 2014-11-24 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book bridges the gap between general plasma physics lectures and the real world problems in MHD stability. In order to support the understanding of concepts and their implication, it refers to real world problems such as toroidal mode coupling or nonlinear evolution in a conceptual and phenomenological approach. Detailed mathematical treatment will involve classical linear stability analysis and an outline of more recent concepts such as the ballooning formalism. The book is based on lectures that the author has given to Master and PhD students in Fusion Plasma Physics. Due its strong link to experimental results in MHD instabilities, the book is also of use to senior researchers in the field, i.e. experimental physicists and engineers in fusion reactor science. The volume is organized in three parts. It starts with an introduction to the MHD equations, a section on toroidal equilibrium (tokamak and stellarator), and on linear stability analysis. Starting from there, the ideal MHD stability of the tokamak configuration will be treated in the second part which is subdivided into current driven and pressure driven MHD. This includes many examples with reference to experimental results for important MHD instabilities such as kinks and their transformation to RWMs, infernal modes, peeling modes, ballooning modes and their relation to ELMs. Finally the coverage is completed by a chapter on resistive stability explaining reconnection and island formation. Again, examples from recent tokamak MHD such as sawteeth, CTMs, NTMs and their relation to disruptions are extensively discussed.
Book Synopsis Study of Tokamak Plasma Disruptions and Runaway Electrons in a Metallic Environment by : Sundaresan Sridhar
Download or read book Study of Tokamak Plasma Disruptions and Runaway Electrons in a Metallic Environment written by Sundaresan Sridhar and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tokamaks are the devices currently closest to achieve nuclear fusion power and disruptions are unfavorable events in which the plasma energy is lost in a very short timescale causing damage to tokamak structures. RE beams are one of the consequence of disruptions and they carry the risk of in-vessel component damage. Thus, the prevention and control of the RE are of prime importance. The current strategy for runaway electrons is to avoid their generation by a massive material injection (MMI). If their generation cannot be avoided, a 2nd MMI will be used to mitigate the generated RE beam. After the 1st MMI to prevent RE generation, a background plasma of 1st MMI impurities is formed which make the second MMI inefficient to mitigate RE beams inefficient, as observed in the JET tokamak. In this thesis, the physics of the interaction between the RE beam and the mitigation MMI in the presence of a cold background plasma is studied.
Book Synopsis Interpretable Machine Learning for Prediction and Avoidance of Disruptions in Tokamak Plasmas by : Kevin Joseph Montes
Download or read book Interpretable Machine Learning for Prediction and Avoidance of Disruptions in Tokamak Plasmas written by Kevin Joseph Montes and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the first, databases of thousands of discharges on multiple tokamaks were used to develop a random forest disruption predictor, demonstrating a relatively low limit for feasible disruption prediction on Alcator C-Mod when compared to DIII-D and EAST. Its predictions are shown to be interpretable using metrics known as feature contributions, which were made available in real-time experiments on the DIII-D tokamak to inform control actions. For the second contribution, the semi-supervised label spreading algorithm is applied to detect events often preceding disruptions in a large set of discharges, given few manually labeled examples. A method is proposed to construct event databases from scratch with the algorithm, and an accompanying software module was developed and made available for this purpose.
