1. Resonant magnetic perturbation effect on the tearing mode dynamics : Novel measurements and modeling of magnetic fluctuation induced momentum transport in the reversed-field pinch
Sammanfattning : The tearing mode (TM) is a resistive instability that can arise in magnetically confined plasmas. The TM can be driven unstable by the gradient of the plasma current. When the mode grows it destroys the magnetic field symmetry and reconnects the magnetic field in the form of a so-called magnetic island. LÄS MER
2. Tearing mode dynamics in the presence of resonant magnetic perturbations
Sammanfattning : Magnetically confined fusion (MCF) plasmas are typically subject to several unstable modes. The growth of one mode can limit the plasma energy confinement and might cause a termination of the plasma. Externally applied resonant magnetic perturbations (RMPs) are used to control and to mitigate some of the unstable modes. LÄS MER
3. The role of magnetic perturbations in runaway electron and sawtooth dynamics
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
4. The role of magnetic perturbations in runaway electron and sawtooth dynamics
Sammanfattning : Nuclear fusion in tokamaks is a possible future energy production mechanism. Some of the still unsolved problems are connected to the effect of magnetic perturbations on the radial plasma transport. Two such problems are addressed in this thesis. LÄS MER
5. Towards reliable seismic hazard assessment in underground mines
Sammanfattning : Seismic hazard is used for national, regional, and local level to ensure safe constructions in specific areas. In the mining industry this information is valuable e.g. to design infrastructure or rock support, to reduce the risk of rock burst and to minimise the risk of locating personnel in hazardous areas.
