AbstractMost treatments of lower hybrid waves include either electromagnetic or warm-plasma effects, but not both. Here we compare numerical dispersion curves for lower hybrid waves with a new analytic dispersion relation that includes both warm and electromagnetic effects. Very good agreement is obtained over significant ranges in wavenumber and plasma parameters, except where ion magnetization effects become important.

We investigate particle acceleration by strong lower-hybrid turbulence produced by the relaxation of an energetic perpendicular ion ring distribution. Ion ring distributions are associated with counterstreaming plasma flows in a magnetic field, and are found at perpendicular shocks as a result of ion reflection from the shock surface. Using a 2½D particle-in-cell (PIC) code that is fully electromagnetic and relativistic, we show that the ion ring is unstable to the generation of strong plasma turbulence at the lower-hybrid resonant frequency. The lower-hybrid wave turbulence collapses in configuration space, producing density cavities. The collapse of the cavities is halted by particle acceleration, producing energetic electron and ion tails. For solar flare plasmas with temperatures of 1 keV and a ratio of the plasma frequency to the electron cyclotron frequency of ½, we demonstrate electron acceleration to energies up to MeV, while the ions are accelerated to energies in the region of several MeV.

Dust-lower-hybrid waves in quantum plasma have been studied. The dispersion relation of the dust-lower-hybrid wave has been examined using the quantum hydrodynamic model of plasma in an ultra-cold Fermi dusty plasma in the presence of a uniform external magnetic field. Graphical analysis shows that the electron Fermi temperature effect and the quantum corrections give rise to significant effects on the dust-lower-hybrid wave of the magnetized quantum dusty plasma.

De nos jours, les plasmas sont principalement utilisés à des fins industrielles. L'un des exemples les plus fréquemment cités d'utilisation industrielle est la production d'énergie électrique via des réacteurs nucléaires à fusion. Pour contenir le plasma correctement à l'intérieur du réacteur, un champ magnétique est imposé en arrière-plan, et la densité et la température du plasma doivent être précisément contrôlées. Cela est effectué en envoyant des ondes électromagnétiques à des fréquences et dans des directions spécifiques en fonction des caractéristiques du plasma.La première partie de cette thèse de doctorat est consacrée à l'étude du modèle du plasma avec un fort champ magnétique en arrière-plan, ce qui correspond à un métamatériau hyperbolique. L'objectif est d'étendre les résultats existant en 2D au cas 3D et de dériver une condition de radiation. Nous introduisons une séparation des champs électriques et magnétiques ressemblant à la décomposition TE et TM habituelle, puis nous présentons quelques résultats sur les deux problèmes résultants. Les résultats sont dans un état très partiel et constituent un brouillon approximatif sur le sujet.La deuxième partie étudie l'EDP dégénérée associée aux ondes résonantes « lower-hybrid » dans le plasma. Le problème aux limites associé est bien posé dans un cadre variationnel « naturel ». Cependant, ce cadre n'inclut pas le comportement singulier présenté par les solutions physiques obtenues via le principe d'absorption limite. Ce comportement singulier est important du point de vue physique car il induit le chauffage du plasma mentionné précédemment. Un des résultats clés de cette deuxième partie est la définition d'une notion de saut à travers l'interface à l'intérieur du domaine, ce qui permet de caractériser la décomposition de la solution d'absorption limite en parties régulière et singulière
Nowadays, plasmas are mainly used for industrial purpose. One of the most frequently cited examples of industrial use is electric energy production via fusion nuclear reactors. Then, in order to contain plasma properly inside the reactor, a background magnetic field is imposed, and the density and temperature of the plasma must be precisely controlled. This is done by sending electromagnetic waves at specific frequencies and directions depending on the characteristics of the plasma.The first part of this PhD thesis consists in the study of the model of plasma in a strong background magnetic field, which corresponds to a hyperbolic metamaterial. The objective is to extend the existing results in 2D to the 3D-case and to derive a radiation condition. We introduce a splitting of the electric and magnetic fields resembling the usual TE and TM decomposition, then, it gives some results on the two resulting problems. The results are in a very partial state, and constitute a rough draft on the subject.The second part consists in the study of the degenerate PDE associated to the lower-hybrid resonant waves in plasma. The associated boundary-value problem is well-posed within a ``natural'' variational framework. However, this framework does not include the singular behavior presented by the physical solutions obtained via the limiting absorption principle. Notice that this singular behavior is important from the physical point of view since it induces the plasma heating mentioned before. One of the key results of this second part is the definition of a notion of weak jump through the interface inside the domain, which allows to characterize the decomposition of the limiting absorption solution into a regular and a singular parts

The whole universe is filled with plasma. There are different kinds of plasmas filling large volumes, separated by distinct boundaries. Many important energy conversion, particle acceleration and plasma transport processes occur at these boundaries, and therefore it is important to study the plasma processes there. It will for example help us to better understand the interaction and energy exchange between the Sun and the Earth. The lower hybrid drift waves (LHDW) are strong plasma waves that are often excited within boundaries, but their role in different plasma processes are still unclear. Many studies of the LHDW have been done, both in space and in laboratory. However, the LHDW are electron scale waves, and due to their small wavelength it has been difficult to study them in detail experimentally. For the first time we are able to make very detailed studies of the LHDW using observations by the Cluster spacecraft in the plasma surrounding Earth. By making cross spacecraft correlations of the electric field and examining existence conditions, we were able to determine the velocity of propagation and wavelength of the waves and thereby identify them as LHDW. We also calculate the electrostatic potential and find that it corresponds to about a third of the electron temperature. This indicate that they might be able to affect the electrons and thus take part in the processes within the boundary layer. By deriving a linear relation between the electrostatic potential, and the wave magnetic field, we compare them both and find that they correspond very well. We can use this to estimate the electrostatic potential in cases when cross spacecraft correlation is not possible.

Cataloged from PDF version of thesis.
Includes bibliographical references (pages 195-204).
In this thesis, two experimental investigations are presented in an attempt to understand the loss of lower hybrid current drive (LHCD) efficiency in reactor-relevant, high-density plasmas on the diverted Alcator C-Mod tokamak. While the previous work has identified that edge interactions, such as collisional absorption and excessive up-shift of the parallel refractive index due to full-wave effects, could potentially explain the observed loss of LHCD efficiency in a wide range of line-averaged densities, these simulations still over-predict the fast electron population generated by LHCD above line-averaged densities of 1 x 10²⁰ m- ³. It is critical to identify remaining mechanisms in order to demonstrate advanced tokamak operation at reactor-relevant densities. The first investigation is to perform microwave backscattering experiments to detect electrostatic lower hybrid (LH) waves in the scrape-off layer (SOL), where a significant amount of the injected LH power may be deposited due to a number edge loss mechanisms. An existing ordinary-mode (O-mode) reflectometer system has been modified to measure the backscattered O-mode wave as a result of Bragg backscattering of the incident O-mode wave off the LH wave. The detection of LH waves in a region that is not magnetically connected to the launcher implies a weak single pass absorption of LH waves in high density plasmas. The observed spectral width of the backscattered signals indicates the presence of non-linear effects on the propagation of LH waves, but no experimental evidence is found to confirm whether the non-linear mechanism that is responsible for the observed spectral broadening is responsible for the observed loss of LHCD efficiency. The second investigation is to examine the change in LH frequency spectra due to density-dependent non-linear effects, such as parametric decay instability (PDI) above the line-averaged density of 1 x 10²⁰ m-³, using the probes installed on the launcher, outer divertor, and inner wall. Ion cyclotron PDI is found to be excited above line-averaged densities of 1 x 10²⁰ m -³, suggesting that ion cyclotron PDI may be a remaining mechanism to understand the loss of LHCD efficiency. Ion cyclotron PDI is observed to be excited not only at the low-field-side edge but also at the high-field-side (HFS) edge of Alcator C-Mod, further corroborating that LH waves are weakly absorbed on their first pass. Evidence of pump depletion is found with the onset of ion cyclotron PDI at the HFS edge in lower-single-null plasmas. However, no apparent pump depletion is seen when the magnetic geometry is switched to an upper-single-null. Moreover, ion cyclotron PDI is excited at the LFS edge in this case. Thus, the role of the observed ion cyclotron PDI on the loss of LHCD efficiency needs further experimental investigation to be conclusive due to the different ion cyclotron PDI strength and excitation location, depending on magnetic configurations. A summary of the new findings of this thesis is as follows: First measurements of PDI below the classical threshold (wo/wLH(0) ~~ 2). First ever observation of PDI on HFS of a tokamak and its relationship to being in a multi-pass damping regime. " Advancement of PDI as a candidate mechanism for the LHCD density limit.

Cette thèse fournit en premier lieu une brève introduction à la fusion nucléaire par confinement magnétique et aux tokamaks. Elle explique la nécessité de disposer de systèmes électromagnétiques aux fréquences cylctronique ionique (ICRF) et hybride basse (LHRF) pour le chauffage du plasma et la génération de courant. En second lieu les conditions à satisfaire afin d’assurer une propagation de l'onde plasma et une résonance onde-particules sont définies.

Dans une 1ere partie, on construit des formulations variationnelles associées aux équations de Maxwell résonantes. Les équations dégénèrent dans le domaine, entraînant la non-unicité et la singularité des solutions. L’ajout de viscosité permet de les désingulariser, et par un procédé d’absorption limite, lorsque ce paramètre de viscosité tend vers zéro, on identifie la solution physique. Mais la dégénérescence sépare le problème à la limite en deux équations sur des domaines différents couplées par leur interface, le long de laquelle les solutions explosent. Ce travail caractérise la solution limite de manière explicite comme solution d’une formulation bien posée, ce qui permet d’approcher numériquement la solution physique des équations de Maxwell résonantes. L’étude est motivée par la modélisation de résonances hybrides dans un plasma de fusion. Une 2nde partie concerne les méthodes numériques de décomposition de domaine (DDM). En présence de coins et de points de croisement, lorsqu’on utilise un mailleur automatique par exemple, il est nécessaire de traiter ces points pour obtenir des conditions d’absorption (ABC) ou de transmission (TC) d’ordre supérieur à 1. Nous définissons des ABC d’ordre 2 pour l’équation de Helmholtz sur un domaine à coins, avec en vue des TC traitant les points de croisement. Chaque algorithme présenté est lié à une énergie décroissante et converge
In 1st part, variational formulations associated with resonant Maxwell equations are constructed. The equations degenerate in the domain, leading to the non-unicity and singularity of the solutions. Adding viscosity desingularizes the equations, and a limiting absorption process, when this viscosity parameter goes to zero, allows to identify the physical solution. The degeneracy separates the problem at the limit into two equations on different domains coupled by their interface, along which the solutions blow up. This work explicitly characterizes the limit solution as a solution of a well-posed formulation, which allows the numerical approximation of the physical solution to the resonant Maxwell equations. The study is motivated by the modeling of hybrid resonances in fusion plasma. A 2nd part concerns numerical domain decomposition methods (DDM). In the presence of corners and cross points, when using an automatic mesher for example, it is necessary to treat these points to obtain absorption (ABC) or transmission (TC) conditions of order higher than 1. We define ABCs of order 2 for the Helmholtz equation on a polygonal domain, with the further intention of deriving TCs treating cross points. Each algorithm presented is endowed with a decreasing energy and is convergent

Durant les 15 dernières années, le couplage fort lumière-matière avec des matériaux organiques a attiré un intérêt croissant, notamment à cause des valeurs extrêmes que peut atteindre l'écart énergétique entre les modes couplés dans ces systèmes. Ces modes couplés sont des hybrides lumière-matière, aussi appelés états polaritons et notés habituellement P+ et P-. La valeur de I' écart énergétique entre les modes couplés, également appelé énergie de Rabi-splitting, est provoqué par une transition efficace de dipôle moments entre des molécules et aussi par des cavités ou des plasmons en surface de petits volumes en mode de micro-Fabry-Pérot métalliques (FP) qui sont utilisés dans ces études. Rabi-splittings - 1eV représente souvent une fraction importante de l'énergie de transition électronique, dans ce cas, le système est appelé dans le régime de couplage ultra-forte. Dans ce régime, la physico-chimie des molécules ou des propriétés des matériaux du système couplé peuvent être modifié. En effet, d'effet a déjà été montré sur les voies de relaxation dans le système couplé, les taux de réactions photochimiques, le travail d'extraction et de la conductivité des semi-conducteurs organiques dans l'obscurité, entre autres choses. Une étude récente a pu montrer que l'énergie de l'état non-excité dans une étude thermodynamique peut également être décalée dans le régime de couplage ultra-fort. De plus, le couplage fort ne se limite pas à des transitions électroniques, mais peut aussi être utilisé pour perturber les vibrations de l'état non-excité de molécules dans la région infrarouge. Tous ces résultats montrent que le couplage fort en lumière-molécule a beaucoup de potentiel pour le matériel et la science moléculaire et mérite donc une étude plus approfondie
Over the past 15 years, light-matter strong coupling involving organic materials has been of increasing interest due to the very large energy splitting such systems exhibit between the two hybrid light-matter states, also known as the polaritonic states typically denoted P+ and P-. The large energy splitting, so-called Rabi splitting, is the result of the high transition dipole moments of the molecules and the small mode volumes of micro-metallic Fabry-Pérot (FP) cavities or surface plasmons used in these studies. Rabi-splittings -1 eV have been observed, often representing a significant fraction of the electronic transition energy in which case the system is said to be in the ultra-strong coupling regime. ln this regime the physical chemistry of molecules or the properties of materials of the coupied system should be modified. lndeed, it has already been shown to affect the relaxation pathways in the coupled system, the rates of photochemical reactions, thework-function and conductivity of organic-semiconductors in the dark, among other things. A recent thermodynamic study demonstrated that the ground state energy can also be shifted in theultra-strong coupling regime. Moreover, the strong coupling is not limited to electronic transitions, but also can be used to perturb the ground-state vibrations of molecules in the infrared region. Ali these results suggest that light-molecule strong coupling has much potential for material and molecular science and therefore merits further study
