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

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

    Sammanfattning : 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. LÄS MER

    Författare :Frida Eriksson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NBI; numerical modelling; turbulence; drift waves; bump-on-tail; density peaking; Fusion plasma physics; wave-particle interaction;

    Sammanfattning : The presence of highly energetic (fast) ions, be it fusion born alpha particles or ions accelerated by auxiliary heating schemes, can affect the heating and transport of all particles in the plasma through two main mechanisms. First, fast ions may excite fast ion driven instabilities. LÄS MER
