Academic Career and Research Areas

Gregor Birkenmeier studied physics from 2002-2008 in Freiburg and Stuttgart. He got his PhD 2012 from Stuttgart University. Since he was a PostDoc at the Max Planck Institute for Plasma Physics (2012-2014) and at the TU Munich (2014-2017), he investigated the physics of the plasma edge at the fusion experiment ASDEX Upgrade. At the same facility, his group develops a special particle beam probe allowing for improved measurements of the structure formation at the plasma edge.  

 

The research of Gregor Birkenmeier (b. 1981) focuses on the formation of self-organized structures in high temperature plasmas. Modern fusion experiments confine a high temperature plasma by means of toroidal magnetic fields, in order to produce energy from nuclear fusion of hydrogen. Self-organized flows and filaments at the edge of the plasma can facilitate or hamper the operation of a future fusion power plant. Therefore, the young investigator group aims at a better understanding of the physics of the structure formation at the plasma edge.
