Disputas - Master of Science Gregor Decristoforo

Master of Science Gregor Decristoforo will Friday May 21th at 12:15 publically defend his thesis for the PhD degree in Science

Title of the thesis:

«Numerical simulations and stochastic modeling of intermittent fluctuations in magnetized plasmas»

 

Popular scientific abstract:

The exhaust of heat and particles in the boundary of contemporary fusion experiments remains to this day a major obstacle on the road to commercially viable fusion energy production. It is recognized, that plasma turbulence is the main cause for particle transport, leading to damaging plasma-wall interactions. Due to the complexity of the physics involved in the boundary of fusion devices, numerical simulations are utilized in order to gain a better understanding of boundary plasmas.

In this thesis, well-established models for fusion plasmas are analyzed. The statistical properties of these numerical simulations are validated by a stochastic model which stands in excellent agreement with experimental measurements. The presented work identifies which numerical models accurately describe boundary plasmas and thereby which models can be utilized for simulations of current and next generation fusion devices.
