  2. 1. Drift ballooning and ITG instabilities in tokamak plasmas

    Author : Bhanpersad Jhowry; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ballooning mode; torus; FLR effects; toroidal instabilities; reverse shear; elongation; ITG-mode;

    Abstract : A major aim in fusion research is to understand, predict and control confined plasma instability in terms of equilibrium, stability and transport. Substantial progress has been made in recent years in understanding stability and transport in terms of MHD instability and drift wave instabilities. READ MORE

    Author : Johan Anderson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; fusion plasmas; instabilities; toroidal geometry; drift waves;

    Abstract : One of the main concerns in fusion research is to understand the anomalously high transport in magnetically confined plasmas. In recent years, substantial progress in the understanding of transport in terms of drift waves in fusion plasmas has been achieved. READ MORE

  6. 4. Temperature Gradient Instabilities and Transport in Toroidal Plasmas

    Author : Mats Fröjdh; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis focuses on temperature gradient driven modes and their implications for heat and particle transport in toroidal plasmas. Some of the consequences of including an ion impurity species in a model for low frequency electrostatic modes and fluctuation driven transport are discussed. READ MORE

  7. 5. Turbulent impurity transport in tokamaks

    Author : Albert Mollén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gyrokinetic; tokamak; impurity; poloidal asymmetry.; turbulence; transport; fusion plasma physics;

    Abstract : Nuclear fusion is foreseen as one of the options for future energy production. One of the remaining scientific challenges for establishing the physics basis of future magnetic fusion reactors is to find scenarios where the impurity content in the core can be kept low. READ MORE
