  1. 1. Bridge functions in strongly coupled plasmas : theory, simulations and applications

    Författare :Federico Castello Lucco; Svetlana V. Ratynskaia; Panagiotis Tolias; Giorgio Pastore; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Teoretisk fysik; Theoretical Physics; Atomic; Subatomic and Astrophysics; Atomär fysik; subatomär fysik och astrofysik;

    Sammanfattning : Strongly coupled or non-ideal plasmas are multi-component charged systems in which at least one species possesses an average interaction energy that is comparable or larger than its thermal energy. Non-ideal plasmas are naturally occurring in dense astrophysical objects (e.g. giant planet interiors) but also engineered in the laboratory (e. LÄS MER

  3. 2. A study of the structure and dynamics of Saturn's inner plasma disk

    Författare :Mika Holmberg; Jan-Erik Wahlund; Nikolai Piskunov; Svetlana Ratynskaia; Thomas Cravens; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Planetary magnetospheres; Saturn; magnetospheric dynamics; Saturn s inner plasma disk; ring plasma; ion densities; ion velocities; dayside nightside asymmetry; ion loss rates; Cassini; Langmuir probe; RPWS; Space Physics; Rymdfysik;

    Sammanfattning : This thesis presents a study of the inner plasma disk of Saturn. The results are derived from measurements by the instruments on board the Cassini spacecraft, mainly the Cassini Langmuir probe (LP), which has been in orbit around Saturn since 2004. LÄS MER

  4. 3. Modeling High Power Impulse Magnetron Sputtering Discharges

    Författare :Chunqing Huo; Nils Brenning; Svetlana Ratynskaia; James Bradley; KTH; []
    Nyckelord :;

    Sammanfattning : HiPIMS, high power impulse magnetron sputtering, is a promising technology that has attracted a lot of attention ever since its appearance. A time-dependent plasma discharge model has been developed for the ionization region in HiPIMS discharges. LÄS MER

  5. 4. Object-plasma interaction in the vicinity of Enceladus

    Författare :Jonas Olson; Svetlana Ratynskaia; Padma Shukla; KTH; []
    Nyckelord :;

    Sammanfattning :     The Cassini spacecraft orbits Saturn since 2004, carrying a multitude of instruments for studies of the plasma environment around the planet as well as the constituents of the ring system. Of particular interest to the present thesis is the large E ring, which consists mainly of water ice grains, smaller than a few micrometres, referred to as dust. LÄS MER

  7. 5. Plasma and dust interaction in the magnetosphere of Saturn
