  1. 1. Stability and Statistical Analysis of Transient Waves in Fusion Plasmas

    Author : Gergö Pokol; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; short-time Fourier transform; transient MHD mode; wavelet transform; quasi-linear diffusion; runaway electron; transient transport; stellarator; tokamak disruption; fusion plasma physics; whistler wave;

    Abstract : Thermonuclear energy generation in magnetically confined plasmas offers an appealing energy source for coming generations. Some of the still unsolved problems in fusion plasma physics involve plasma transport and stability of plasma waves. Two such problems are addressed in the present thesis. READ MORE

  4. 4. Microinstabilities in Advanced Tokamak and Stellarator Geometries

    University dissertation from Stockholm : Alfvénlaboratoriet

    Author : Ansar Mahmood; [2008]
    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).

  5. 5. Numerical studies of current profile control in the reversed-field pinch

    University dissertation from Stockholm : KTH

    Author : Jon-Erik Dahlin; KTH.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Reversed-Field Pinch; RFP; Current Profile Control; CPC; DEBS; DEBSP; active control; feedback; MHD.; NATURAL SCIENCES Physics Geocosmophysics and plasma physics Fusion; NATURVETENSKAP Fysik Geokosmofysik och plasmafysik Fusion;

    Abstract : The Reversed-Field Pinch (RFP) is one of the major alternatives for realizing energy production from thermonuclear fusion. Compared to alternative configurations (such as the tokamak and the stellarator) it has some advantages that suggest that an RFP reactor may be more economic. READ MORE
