Simulation and assessment of particle transport in fusion plasmas
Licentiate thesis, 2021
The plasma can be described in a number of different ways, fluid or kinetic descriptions. As the particles are confined to the magnetic field lines due to Lorentz force and this process, called gyromotion, is one of the fastest process in the plasma, it is beneficial to average out this motion. This is the basis of gyrofluid and gyrokinetic descriptions. Several different codes have been devolved such as EDWM, TGLF and GENE etc from the fluid, gyrofluid and gyrokinetic descriptions. All these describes the different instabilities which dominates the plasma: the Ion Temperature Gradient (ITG), Trapped Electron Mode (TEM) and Electron Temperature Gradient (ETG).
After introducing the aforementioned descriptions of the plasma we discuss the density peaking of the plasma as it important for the efficiency of a commercial fusion power plant
