This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans les plasmas de fusion, les parois faisant face aux plasmas sont érodées, ce qui réduit leur durée de vie, et les particules rejetées dégradent le confinement de l'énergie en rayonnant. Nous étudions ce phénomène à l'aide d'une modélisation cinétique de type Vlasov-Poisson. Celle-ci nous permet d'étudier la transition entre un plasma basse pression faiblement collisionnel à l'équilibre thermodynamique et une paroi, en présence d'un champ magnétique. Une étude détaillée de la transition a permis d'établir les mécanismes agissant dans les trois zones qui la composent (gaine de Debye, prégaine magnétique et prégaine collisionnelle). Une attention particulière apportée aux conditions d'entrée des ions dans la gaine a permis de montrer que les collisions pouvaient conduire à la non-satisfaction du critère de Bohm. Nous avons de plus mis en évidence que la présence de la paroi, combinée à celle d'un champ magnétique, induit d'importantes déformations de la distribution des ions, justifiant pleinement le traitement cinétique. L'exploitation des distributions obtenues au niveau de la paroi a permis d'estimer le taux de pulvérisation de celle-ci en fonction du champ magnétique. Nous avons pu montrer qu'un champ magnétique rasant permet non seulement d'étaler le flux ionique sur une plus grande surface, mais aussi de réduire l'énergie des ions la percutant, limitant ainsi sa pulvérisation. Les plasmas étant généralement composés de plusieurs types d'ions, notre modèle a ensuite été étendu au cas des plasmas composés d'argon et d'hélium. Notre étude s'est concentrée sur l'influence d'une seconde espèce ionique sur le critère de Bohm à l'entrée de la gaine de Debye.

This book was released on 1988 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Étude théorique et expérimentale de l'intéraction non linéaire de deux faisceaux d'ondes électromagnétiques. Les modes électroniques du plasma chaud sont d'abord présentés, en insistant sur les effets thermiques intervenant sur les cônes de résonance. Le courant non linéaire et le champ électrique excités sont évalués, de même que l'efficacité du processus. Le travail expérimental repose sur la caractérisation des modes électrostatiques, réalisée dans un double-plasma en champ magnétique.

Download or read book Topics in Kinetic Theory written by Thierry Passot and published by American Mathematical Soc.. This book was released on 2005 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers a variety of topics related to kinetic theory in neutral gases and magnetized plasmas, with extensions to other systems such as quantum plasmas and granular flows. A comprehensive presentation is given for the Boltzmann equations and other kinetic equations for a neutral gas, together with the derivations of compressible and incompressible fluid dynamical systems, and their rigorous justification. Several contributions are devoted to collisionless magnetized plasmas. Rigorous results concerning the well-posedness of the Vlasov-Maxwell system are presented. Special interest is devoted to asymptotic regimes where the scales of variation of the electromagnetic field are clearly separated from those associated with the gyromotion of the particles. This volume collects lectures given at the Short Course and Workshop on Kinetic Theory organized at the Fields Institute of Mathematical Sciences in Toronto during the Spring of 2004.

Download or read book Quantum Mechanics Volume 3 written by Claude Cohen-Tannoudji and published by John Wiley & Sons. This book was released on 2019-12-16 with total page 790 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new, third volume of Cohen-Tannoudji's groundbreaking textbook covers advanced topics of quantum mechanics such as uncorrelated and correlated identical particles, the quantum theory of the electromagnetic field, absorption, emission and scattering of photons by atoms, and quantum entanglement. Written in a didactically unrivalled manner, the textbook explains the fundamental concepts in seven chapters which are elaborated in accompanying complements that provide more detailed discussions, examples and applications. * Completing the success story: the third and final volume of the quantum mechanics textbook written by 1997 Nobel laureate Claude Cohen-Tannoudji and his colleagues Bernard Diu and Franck Laloë * As easily comprehensible as possible: all steps of the physical background and its mathematical representation are spelled out explicitly * Comprehensive: in addition to the fundamentals themselves, the books comes with a wealth of elaborately explained examples and applications Claude Cohen-Tannoudji was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris where he also studied and received his PhD in 1962. In 1973 he became Professor of atomic and molecular physics at the Collège des France. His main research interests were optical pumping, quantum optics and atom-photon interactions. In 1997, Claude Cohen-Tannoudji, together with Steven Chu and William D. Phillips, was awarded the Nobel Prize in Physics for his research on laser cooling and trapping of neutral atoms. Bernard Diu was Professor at the Denis Diderot University (Paris VII). He was engaged in research at the Laboratory of Theoretical Physics and High Energy where his focus was on strong interactions physics and statistical mechanics. Franck Laloë was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris. His first assignment was with the University of Paris VI before he was appointed to the CNRS, the French National Research Center. His research was focused on optical pumping, statistical mechanics of quantum gases, musical acoustics and the foundations of quantum mechanics.
