  2. 1. Modelling Ion Cyclotron Resonance Heating and Fast Wave Current Drive in Tokamaks

    Author : Abdul Hannan; Torbjörn Hellsten; Dirk van Eester; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thermonuclear fusion; Tokamak; DIII-D; JET; ITER; DEMO; ICRF; ICRH; Fast magnetosonic waves; TTMP; ELD; ICRH; Thermonuclear;

    Abstract : 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. READ MORE

  4. 2. Optimization Methods for Robust Control with Application to Resistive Wall Modes in Tokamaks

    Author : Carl-Magnus Fransson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; H?; fusion; QFT; performance; tokamak; optimization; robustness; structured singular value; control; plasma; resistive wall modes; LMI; PID control;

    Abstract : In many research areas physical systems are described by mathematical models. We focus here on systems that are regulated by a controller, typically realized by software, whose design involves certain parameters. READ MORE

  5. 3. Turbulent and neoclassical transport in tokamak plasmas

    Author : Istvan Pusztai; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; thermonuclear fusion; tokamaks; microinstabilities; transport analysis; isotope effect; impurity transport; neoclassical transport; transport barriers; turbulent transport;

    Abstract : One of the greatest challenges of thermonuclear fusion is to understand, predict and to some extent control particle and energy transport in fusion plasmas. In the present thesis we consider theoretical and experimental aspects of collisional and turbulent transport in tokamak plasmas. READ MORE

  6. 4. Simulation and analysis of radiation from runaway electrons

    Author : Mathias Hoppe; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; tokamak; runaway electrons; synthetic diagnostics; fusion; synchrotron radiation; plasma physics; bremsstrahlung;

    Abstract : Electron runaway constitutes one of the primary threats to future tokamak fusion reactors such as ITER. Successful prevention and mitigation of runaways relies on the development of theoretical models which accurately describe the dynamics of runaway electrons, and these models must in turn be validated in experiments.
