  1. 1. 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 :NATURAL SCIENCES; NATURVETENSKAP; 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

  2. 2. 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

  3. 3. 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

  4. 4. Plasma and dust interaction in the magnetosphere of Saturn

    Författare :Jonas Olson; Svetlana Ratynskaia; Carmine Castaldo; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; saturn; dusty plasma;

  5. 5. Modelling of macroscopic melt motion in fusion devices

    Författare :Emil Thorén; Svetlana V. Ratynskaia; Panagiotis Tolias; Guy Matthews; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Magnetic confinement fusion is one of the most well developed methods envisioned to achieve thermonuclear fusion energy in the future. A central obstacle that remains in the way of safe and sustainable reactor operation is the interaction that occurs between the plasma and vessel wall components. LÄS MER
