  4. 12. Thermonuclear Instabilities and Plasma Edge Transport in Tokamaks

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

    Abstract : 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).

  5. 13. Modelling of macroscopic melt motion in fusion devices

    Author : Emil Thorén; Svetlana V. Ratynskaia; Panagiotis Tolias; Guy Matthews; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Magnetic confinement fusion is one of the most well developed methods envisioned to achieve thermonuclear fusion energy in the future. A central obstacle that remains in the way of safe and sustainable reactor operation is the interaction that occurs between the plasma and vessel wall components. READ MORE

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

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

    Abstract : 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. READ MORE

  7. 15. Microinstabilities in Advanced Tokamak and Stellarator Geometries

    Author : Ansar Mahmood; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tokamaks; microinstabilities; fusion plasmas; ITG; drift waves; stellarators;

    Abstract : The anomalous particle and heat transport observed in magnetically confined plasmas is generally attributed to plasma turbulence driven by short-scale instabilities, called microinstabilities. Understanding the stability limits of microinstabilities and their dependency on the equilibrium configuration is of paramount importance in the effort to predict the performance of future fusion devices such as the International Thermonuclear Experimental Reactor (ITER).
