General radio-frequency properties of bounded plasma systems in connection with the production and heating of dense plasmas

The present review is centred on work done at the Laboratoire de Physique des Plasmas of the Ecole Royale Militaire and the references are therefore mostly those of the laboratory. We cover the following ground : Firstly, a brief review of the linear resonance properties of bounded plasma systems in the electron wave domain together with some applications to diagnostics and plasma coated antennas. Secondly, the properties of radio-frequency resonantly sustained plasmas with densities high above critical density and it is stressed that these interesting plasma sources can be understood on the basis of the general resonance properties of bounded systems. Thirdly, we study the absorption and resonance properties of hot-ion magnetized plasma columns in the magneto-ion domain, i.e. in that domain in which both the ions (largely because of the magnetic field) and the non-zero temperature of electrons play a significant role. We discover there absorption zones and a wealth of interesting plasma resonances which are due to the bounded hot character of the plasma and which are indirectly linked to the usual characteristic frequencies (ion cyclotron, lower hybrid) of the cold infinite plasma.

Efimov physics in two nuclear-spin sublevels of bosonic lithium is studied and it is shown that the positions and widths of recombination minima and Efimov resonances are identical for both states within the experimental errors, which indicate that the short-range physics is nuclear-spin independent. We also find that the Efimov features are universally related across Feshbach resonances. These results crucially depend on careful mapping between the scattering length and the applied magnetic field which we achieve by characterization of the two broad Feshbach resonances in the different states by means of rf-spectroscopy of weakly bound molecules. By fitting the binding energies numerically with a coupled channels calculation we precisely determine the absolute positions of the Feshbach resonances and the values of the singlet and triplet scattering lengths.On présente une étude expérimentale de l'effet d'Efimov dans deux états de spin nucléaire du lithium bosonique, et l'on montre que les positions et les largeurs des résonances d'Efimov sur le taux de recombinaison sont les mêmes pour les deux états à l'incertitude des mesures près, ce qui indique que la physique à courte portée ne dépend pas du spin nucléaire. On trouve également que les paramètres clés de la physique d'Efimov obéissent aux relations universelles attendues sur toute la résonance de Feshbach. Ces résultats dépendent crucialement de la connnaissance de la longueur de diffusion en fonction du champ magnétique, déduite d'une caractérisation des deux résonances de Feshbach larges dans les différents états par spectroscopie radio-fréquence des états moléculaires faiblement liés. En ajustant les énergies de liaison à l'aide d'un modèle numérique à voies couplées, on détermine les positions absolues des résonances de Feshbach and les valeurs des longueurs de diffusion singulet et triplet.
