    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thermonuclear fusion; Tokamak; DIII-D; JET; ITER; DEMO; ICRF; ICRH; Fast magnetosonic waves; TTMP; ELD; ICRH; Thermonuclear;

    Sammanfattning : Fast magnetosonic waves in the ion cyclotron range of frequencies have the potential to heat plasma and drive current in a thermonuclear fusion reactor. A code, SELFO-light, has been developed to study the physics of ion cyclotron resonantheating and current drive in thermonuclear fusion reactors. LÄS MER

  4. 3. Pressure driven instabilities in the reversed-field pinch : numerical and theoretical studies

    Författare :Ahmed Akram Mirza; Jan Scheffel; Roberto Paccagnella; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fusion plasma; thermonuclear; Reversed-field pinch; resistive MHD; resistive g modes; thermal conduction; the boundary value theory;

    Sammanfattning : According to classical linearized resistive magnetohydrodynamics theory, pressuredriven modes are unstable in the reversed-field pinch (RFP) due to unfavorable magnetic field line curvature. The result is based on the assumption of an adiabatic energy equation where anisotropic thermal conduction effects are ignored as compared to convection and compression. LÄS MER

  7. 5. Thermonuclear Instabilities and Plasma Edge Transport in Tokamaks

    Författare :Tünde Fülöp; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : High-energy ions generated by fusion reactions in a burning fusion plasma may give rise to different types of wave instabilities. The present thesis investigates two types of such instabilities which recently have been observed in fusion experiments: the Toroidal Alfvén Eigenmode (TAE) instability and the magnetoacoustic cyclotron instability (MCI) which is predicted to give rise to ion cyclotron emission (ICE).
