A fusion plasma consists of deuterium, tritium, its fusion product helium and unfortunately also impurities in form of heavy ions like carbon and tungsten.  The parallel dynamics of the different species are very important to understand ahead of future fusion reactors; e.g. will heavier ions be left in the outer layer of a fusion reactor or will they be embedded in the plasma and advected/transported along the magnetic field lines to the designed place for removing of the exhausted plasma?

In the absence of collisions, we do expect kinetic effects to play a role in the dynamics. The project set out to investigate the kinetic aspect of the transport in the outer layer of a fusion reactor. But, as electrons have a much smaller mass than ions their thermal velocities are much faster than ions. Therefore, only the ions are treated kinetically and electrons are treated either adiabatically or as a fluid.

In this project, the students will create a hybrid 1-D particle code, coded in either Python or Matlab. Each particle act under the influence of a combined electrical field created by all particles. Based on realistic parameters from the ASDEX Upgrade fusion reactor and for a wide combination of different ions, the parallel distribution of the different species should be determined.
