IPP scientist Dr. Benedikt Geiger is one of 17 young researchers to be selected by the Helmholtz Association from 250 applicants to set up his own research group. This was preceded by a multi-stage competition process with external expert assessment. Benedikt Geiger will now be supported for five years with 250,000 Euro p.a.
Benedikt Geiger, born 1982 in Rosenheim, Germany, is conducting research on particle motion in hot fusion plasmas. This involves two different particle species: Firstly, there are the fast helium nuclei produced in the fusion process, these ensuring through their high kinetic energy that the plasma retains its temperature even without heating. The energy balance of the power plant requires that these particles remain confined in the magnetic cage long enough to allow them to pass on their energy to the plasma. Secondly, there are the heavy impurity particles emitted by the wall of the plasma vessel. These extract thermal energy from the plasma and conduct it out of the plasma in the form of electromagnetic waves. These unwanted particles should therefore be removed from the magnetic cage as soon as possible.
