  1. 1. Drift-Type Waves in Rotating Tokamak Plasma

    Författare :Elina Asp; Vladimir Pavlenko; Hans Nordman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Space and plasma physics; fusion; plasma; tokamak; rotation; drift; ship; ITG; TE; Landau; Te Ti; hot-electron; confinement; stiffness; Weiland; Rymd- och plasmafysik; Space physics; Rymdfysik; Space and Plasma Physics; rymd- och plasmafysik;

    Sammanfattning : The concept of energy production through the fusion of two light nuclei has been studied since the 1950’s. One of the major problems that fusion scientists have encountered is the confinement of the hot ionised gas, i.e. the plasma, in which the fusion process takes place. LÄS MER

  3. 2. Collisional transport in edge transport barriers and stellarators

    Författare :Stefan Buller; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fusion; tokamak; plasma physics; stellarator; impurity transport; collisional transport; transport; pedestal;

    Sammanfattning : Nuclear fusion has the potential to generate abundant and clean energy. In magnetic confinement fusion, the temperatures needed to achieve fusion are obtained by confining a hot plasma with magnetic fields. LÄS MER

  4. 3. Simulation and assessment of particle transport in fusion plasmas

    Författare :Emil Fransson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Fusion -- Plasma physics -- Turbulent transport --Gyrofluid --Gyrokinetic;

    Sammanfattning : A civilized society need energy to function. An attractive new energy source is nuclear fusion with its abundance of fuel, intrinsic safety and limited environmental impact. Although the concept of fusion for energy has been well understood for over a century, to create it here on earth has been more irksome. LÄS MER

  5. 4. Disruption Mitigation in Tokamaks with Massive Material Injection

    Författare :Oskar Vallhagen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; shattered pellet injection; fusion plasma; disruption mitigation; runaway electron;

    Sammanfattning : The sudden loss of confinement of the energy content of fusion plasmas in off-normal events, called disruptions, is among the most severe threats to the future of fusion energy based on the tokamak design. An efficient disruption mitigation system will therefore be of utmost importance for future large, high-current devices such as ITER. LÄS MER

  7. 5. Runaway-electron model development and validation in tokamaks

    Författare :Mathias Hoppe; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetic confinement fusion; Fokker--Planck equation; synchrotron radiation; tokamaks; runaway-electrons; plasma physics;

    Sammanfattning : Magnetic confinement fusion (MCF), in which a hot plasma at more than 100 million kelvin is confined using magnetic fields, is the most successful fusion energy concept developed to date. After decades of research, MCF devices designed to demonstrate a positive net energy output are being constructed, completing a crucial milestone on the path to making fusion a commercially viable energy source.
