  1. 1. Kinetic modelling of runaway in plasmas

    Författare :Ola Embréus; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fokker-Planck equation; synchrotron radiation; plasma; runaway; bremsstrahlung; Boltzmann equation;

    Sammanfattning : The phenomenon of runaway occurs in plasmas in the presence of a strong electric field, which overcomes the collisional friction acting on the charged particles moving through the plasma. A subpopulation of particles can then be accelerated to energies significantly higher than the thermal energy. LÄS MER

  4. 3. The role of magnetic perturbations in runaway electron and sawtooth dynamics

    Författare :Gergely Papp; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetic perturbation; fusion plasma physics; runaway mitigation; sawtooth oscillation; tokamak; runaway electrons;

    Sammanfattning : As the world's fusion energy program is increasingly focused towards burning plasma experiments, it is important to address the remaining theoretical issues. In this thesis we focus on the effect of magnetic perturbations on the radial plasma transport. LÄS MER

  7. 5. Synchrotron radiation from runaway electrons in plasmas

    Författare :Adam Stahl; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; runaway electrons; critical electric field; fusion plasma physics; tokamak; synchrotron radiation;

    Sammanfattning : Highly relativistic runaway electrons are of great concern in the area of fusion energy research, since their presence in tokamak plasmas have the potential to hinder the successful and stable operation of the device, and potentially cause severe structural damage. In this thesis, runaway electron generation dynamics is investigated using the newly developed efficient computational tool CODE. LÄS MER
