1. Drift-Type Waves in Rotating Tokamak Plasma
Abstract : The concept of energy production through the fusion of two light nuclei has been studied since the 1950’s. One of the major problems that fusion scientists have encountered is the confinement of the hot ionised gas, i.e. the plasma, in which the fusion process takes place. READ MORE

2. Fast Particle Driven Instabilities in Tokamak Plasmas
Abstract : The burning plasmas of the next generation tokamak fusion experiment ITERwill contain signicant populations of highly energetic ions. Both fusion gener-ated alpha particles and fast ions accelerated by auxiliary heating schemes arecapable of exciting instabilities in the Alfven frequency range, which may inturn cause redistribution of energetic particles and lead to deleterious eventssuch as e.

3. Modeling RF waves in hot plasmas using the finite element method and wavelet decomposition : Theory and applications for ion cyclotron resonance heating in toroidal plasmas
Abstract : Fusion energy has the potential to provide a sustainable solution for generating large quantities of clean energy for human societies. The tokamak fusion reactor is a toroidal device where the hot ionized fuel (plasma) is confined by magnetic fields. Several heating systems are used in order to reach fusion relevant temperatures.

4. Collisional transport in edge transport barriers and stellarators
Abstract : Nuclear fusion has the potential to generate abundant and clean energy. In magnetic confinement fusion, the temperatures needed to achieve fusion are obtained by confining a hot plasma with magnetic fields. READ MORE

5. Simulation of runaway electron generation during plasma shutdown by impurity injection
Abstract : Disruptions are dangerous instabilities in tokamaks that should be avoided or mitigated. One possible disruption mitigation method is to inject impurities into the plasma to shut it down in a controlled way. Runaway Electrons (REs) can be generated after the plasma is cooled down bythe impurities and these electrons can damage the tokamak. READ MORE
