  1. 1. 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

  3. 2. Momentum-space dynamics of runaway electrons in plasmas

    Författare :Adam Stahl; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; synchrotron radiation; tokamak; critical electric field; non-linear collision operator; slide-away; runaway electrons; fusion-plasma physics;

    Sammanfattning : Fast electrons in a plasma experience a friction force that decreases with increasing particle speed, and may therefore be continuously accelerated by sufficiently strong electric fields. These so-called runaway electrons may quickly reach relativistic speeds. LÄS MER

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

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

    Sammanfattning : 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.
