  1. 1. Visible spectroscopic diagnostics application and development in fusion plasmas

    Detta är en avhandling från Stockholm : KTH

    Författare :Sheena Menmuir; KTH.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; visible spectroscopy; fusion; Doppler shift; Doppler broadening; TECHNOLOGY Engineering physics Plasma physics with fusion; TEKNIKVETENSKAP Teknisk fysik Plasmafysik med fusion;

    Sammanfattning : Diagnostic measurements play a vital role in experiments. Without them we would be in the dark with no way of knowing what was happening; of understanding the processes and behaviour occurring; or even of judging the success or failure of our experiments. The development of fusion plasma devices is no different. LÄS MER

  2. 2. Ion Beam Analysis of First Wall Materials Exposed to Plasma in Fusion Devices

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Sammanfattning : One major step needed for fusion to become a reliable energy source is the development of materials for the extreme conditions (high temperature, radioactivity and erosion) caused by hot plasmas. The main goal of the present study is to use and optimise ion beam methods (lateral resolution and sensitivity) to characterise the distribution of hydrogen isotopes that act as fuel. LÄS MER

  3. 3. Closed-loop control and identification of resistive shell magnetohydrodynamics for the reversed-field pinch

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Erik Olofsson; KTH.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Engineering physics Plasma physics with fusion; TEKNIKVETENSKAP Teknisk fysik Plasmafysik med fusion; TECHNOLOGY Information technology Automatic control; TEKNIKVETENSKAP Informationsteknik Reglerteknik;

    Sammanfattning : It is demonstrated that control software updates for the magnetic confinement fusion experiment EXTRAP T2R can enable novel studies of plasma physics. Specifically, it is shown that the boundary radial magnetic field in T2R can be maintained at finite levels by feedback. LÄS MER
