This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce travail de thèse est une étude expérimentale, basée sur la spectroscopie d'émission et d'absorption de plasmas chauds et denses créés par une impulsion laser nanoseconde. La physique atomique au sein de ce type de plasmas représente un sujet complexe et de grand intérêt, notamment dans les domaines de l'astrophysique ou de la fusion par confinement inertiel. Du point de vue de la physique atomique, cela revient à déterminer des paramètres tels que l'ionisation moyenne ou l'opacité en fonction de la température électronique et de la densité de matière du milieu. Les codes de physique atomique ont alors besoin de données expérimentales pour se développer et être validés afin qu'ils soient prédictifs sur une large gamme de plasmas. Dans ce travail nous nous concentrons sur des plasmas dont la température électronique varie de 10 eV à plus d'une centaine d'électron-volts pour des densités de matière allant de 10−5 à 10−2 g/cm3. Dans ce manuscrit on distingue deux types de données spectroscopiques qui sont toutes les deux utiles et nécessaires au développement des codes de physique atomique car elles sont caractéristiques de l'état du plasma étudié : 1) des spectres d'absorption obtenus avec des plasmas proche de l'équilibre thermodynamique local de Cu, de Ni et d'Al ; 2) des spectres d'émission obtenus avec des plasmas hors équilibre thermodynamique local de C, d'Al et de Cu. Ce travail met en lumière différentes techniques expérimentales ainsi que diverses comparaisons avec des codes de physique atomique et d'hydrodynamique.
Book Synopsis Étude théorique et expérimentale des effets de hautes densités dans les spectres X émis par les plasmas de laser by : Philippe Malnoult

This book was released on 1989 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: La physique atomique est fondamentale dans les relations d'équilibre et les méthodes de diagnostic pour les plasmas laser. Dans le but d'étendre la théorie des perturbations spectrales à des plasmas ultradenses, nous avons exploré la structure des molécules transitoires qui se forment lors des fluctuations de la position des ions dans les plasmas denses et relativement chauds. Un premier calcul basé sur la distribution uniforme des électrons a permis d'obtenir le potentiel sous forme analytique. Les énergies de transition obtenues révèlent l'excitation de nouvelles composantes spectrales et un important rétrécissement de la largeur Stark des raies. Ce modèle a de plus fourni des conditions initiales adéquates pour un calcul plus général où l'équation de Schrödinger est couplée à l'équation de Poisson dans le cadre d'une théorie à champs autoconsistants. Des mesures spectroscopiques ont été effectuées sur les plasmas obtenus en irradiant des cibles de LiF par un faisceau laser au Néodyme à fréquence quadruple (0.263 μm). Afin de discriminer les effets de transfert radiatif et d'inhomogénéité transverse des effets de perturbation dûs aux particules, l'épaisseur de cible a été calibrée entre 40 et 120 μm. Par une comparaison théorie expérience des spectres obtenus nous avons établi le profil de densité qui varie suivant l'axe laser entre 10^22 et 10^23 cm-3. Une étude spécifique de la zone ultradense a montré que sur l'aile rouge de la raie F IX Ly-β apparaît un satellite dont la position spectrale est en bon accord avec la précédente théorie des molécules transitoires.

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.

Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer. This book was released on 1985-03 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 28 (thesis year 1 983) a total of 10,661 theses titles from 26 Canadian and 197 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 28 reports theses submitted in-1983, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Download or read book Introduction to Plasma Physics and Controlled Fusion written by Francis F. Chen and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: TO THE SECOND EDITION In the nine years since this book was first written, rapid progress has been made scientifically in nuclear fusion, space physics, and nonlinear plasma theory. At the same time, the energy shortage on the one hand and the exploration of Jupiter and Saturn on the other have increased the national awareness of the important applications of plasma physics to energy production and to the understanding of our space environment. In magnetic confinement fusion, this period has seen the attainment 13 of a Lawson number nTE of 2 x 10 cm -3 sec in the Alcator tokamaks at MIT; neutral-beam heating of the PL T tokamak at Princeton to KTi = 6. 5 keV; increase of average ß to 3%-5% in tokamaks at Oak Ridge and General Atomic; and the stabilization of mirror-confined plasmas at Livermore, together with injection of ion current to near field-reversal conditions in the 2XIIß device. Invention of the tandem mirror has given magnetic confinement a new and exciting dimension. New ideas have emerged, such as the compact torus, surface-field devices, and the EßT mirror-torus hybrid, and some old ideas, such as the stellarator and the reversed-field pinch, have been revived. Radiofrequency heat ing has become a new star with its promise of dc current drive. Perhaps most importantly, great progress has been made in the understanding of the MHD behavior of toroidal plasmas: tearing modes, magnetic Vll Vlll islands, and disruptions.
