  1. 1. Rosetta Observations of Plasma and Dust at Comet 67P

    Författare :Fredrik Leffe Johansson; Anders Eriksson; Jan-Erik Wahlund; Nicolas André; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Rosetta; Comets; Plasma; Langmuir Probes; Dust; Spacecraft-plasma interaction; Electrostatic Probes; Rosetta; kometer; plasma; stoft; rymdfarkost-plasma växelverkan; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

    Sammanfattning : In-situ observations of cometary plasma are not made because they are easy. The historic ESA Rosetta mission was launched in 2004 and traversed space for ten years before arriving at comet 67P/Churyumov-Gerasimenko, which it studied in unprecedented detail for two years.

  3. 2. Plasma Characterization & Thin Film Growth and Analysis in Highly Ionized Magnetron Sputtering

    Författare :Jones Alami; Ulf Helmersson; James Bradley; Linköpings universitet; []
    Nyckelord :Highly ionized pulsed magnetron sputtering; HPPMS; HPPIMS; thin film; plasma analysis; Langmuir probe; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The present thesis addresses two research areas related to film growth in a highly ionized magnetron sputtering system: plasma characterization, and thin film growth and analysis. The deposition technique used is called high power pulsed magnetron sputtering (HPPMS). LÄS MER

  4. 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
