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

    Författare :Erik Olofsson; Per Brunsell; Wolfgang Suttrop; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Plasma physics with fusion; Plasmafysik med fusion; Automatic control; 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

  5. 19. Tearing mode dynamics in the presence of resonant magnetic perturbations

    Författare :Richard Fridström; Per Brunsell; Marco Cecconello; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tearing mode; plasma; fusion; reversed-field pinch; RFP; magnetic; confinement; resonant; perturbation; magnetohydrodynamics; MHD; EXTRAP T2R; Madison Symmetic Torus; Fysik; Physics;

    Sammanfattning : Magnetically confined fusion (MCF) plasmas are typically subject to several unstable modes. The growth of one mode can limit the plasma energy confinement and might cause a termination of the plasma. Externally applied resonant magnetic perturbations (RMPs) are used to control and to mitigate some of the unstable modes. LÄS MER

  7. 20. An experimental investigation of electron confinement in reversed-field pinches

    Författare :Anders Welander; KTH; []
    Nyckelord :;

    Sammanfattning : Experimental studies aimed at an improved understanding ofelectron confinement in reversed-field pinch (RFP) plasmas arepresented. Different diagnostic methods have been employed:Thomson scattering and soft x-ray continuum measurements wereused to detect ektrons in the core of the plasma, x-rayemission from an insertable target was used to detect energeticelectrons in the edge region.
