  1. 1. Experimental studies of confinement in the EXTRAP T2 and T2R reversed field pinches

    Författare :Marco Cecconello; KTH; []
    Nyckelord :extap t2; extrap t2r; reversed field pinch; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : The confinement properties of fusion plasmas are affected bymagnetic and electrostatic fluctuations. The determination ofthe plasma confinement properties requires the measurement ofseveral global and local quantities such as the ion andelectron temperatures, the electron and neutral densityprofiles, the radiation emissivity profiles, the ohmic inputpower and the particle and heat diffusivities.

  3. 2. Experimental studies of tearing mode and resistive wall mode dynamics in the reversed field pinch configuration

    Författare :Jenny-Ann Malmberg; KTH; []
    Nyckelord :Nuclear fusion; reversed field pinch; resistive wall instabilities; wall locked modes; tearing modes; resistive shell modes; field errors; Extrap T2; Extrap T2R; TPE-RX;

    Sammanfattning : It is relatively straightforward to establish equilibrium inmagnetically confined plasmas, but the plasma is frequentlysucceptible to a variety of instabilities that are driven bythe free energy in the magnetic field or in the pressuregradient. These unstable modes exhibit effects that affect theparticle, momentum and heat confinement properties of theconfiguration. LÄS MER

  7. 5. Importance of radial profiles in spectroscopic diagnostics applied to the EXTRAP-T2R reversed-field pinch

    Författare :Bob Gravestijn; KTH; []
    Nyckelord :reversed-field pinch; extap-t2r; wuantitaitve plasma spectrosocpy; vuv spectroscopy; line-integrated electron tempreature;

    Sammanfattning : The determination of the plasma confinement propertiesdemand data as the electron temperature, the ionic and electrondensity profiles and the radiative emissivity profiles. Thefocus of this thesis is the importance of radial profiles inspectroscopic diagnostics applied to the EXTRAP-T2Rreversed-field pinch. LÄS MER
