TRR 24:  Fundamentals of Complex Plasmas

Subject Area Physics
Term from 2005 to 2017
Project identifier Deutsche Forschungsgemeinschaft (DFG) - Project number 5486308
 
The Transregional Collaborative Research Centre envisages the comprehensive study of plasmas that contain nanometer or micrometer-sized particles, negative ions, reactive molecules or radicals, or that are influenced by physical and chemical reactions at surfaces. The wide field of phenomena in complex plasmas requires a restriction to a subset of interrelated topics, which are of highest current interest.
-- forces, confinement, order phenomena and collective processes in dusty plasmas
-- chemical and physical processes of ions, atoms and molecules in the plasma and the interaction of the plasma with particles and solid surfaces
-- synthesis and properties of nanometer-sized particles in plasmas and deposition on surfaces
-- waves, self-organisation and plasma stability in multi-component plasmas
-- correlations and collective effects in many-particle systems
The involved project sections, which are arranged in two project areas, form a close network of experimental investigations, analytical theory, computer simulations and advanced data analysis methods.
Project area A - Dynamics and Order PhenomenaInvestigation of wave propagation and stability are performed in plasmas in the presence of negative ions and/or particles under the influence of an external magnetic field. In dusty plasmas the order phenomena, dynamical processes and thermodynamic properties will be investigated in experiments and discharge modelling. A systematic microscopic theory of strongly coupled dusty plasmas will be developed. Instabilities and pattern formation are studied in simulations of Coulomb systems in plasma traps.
Project area B - Reactivity and Surface ProcessesThe spatio-temporal behaviour and local plasma properties of non-stationary molecular plasmas, as well as the particle synthesis in reactive plasmas and chemical processes at particle or solid surfaces are studied. Micrometer-sized particles are used as probes in plasma to analyse charging processes and energy deposition on particles. Integrated data analysis will serve to assess diagnostic methods, to couple models and simulations with the experimental data, and to find optimum designs of experiments. Multi-scale simulations support the modelling of plasma, boundary layers and reactive surface processes.
