Dr. Enno Middelberg auf der Jahrestagung der VLBI Community in Manchester
Dr. Enno Middelberg works as a junior scientist at the Astronomical Institute of the Ruhr-University Bochum. His field of work is the investigation of radio sources with Very Long Baseline Interferomerty (VLBI) techniques. A significant fraction of these radio sources at cosmological distances are so-called active galactic nuclei (AGNs), i.e. black holes with collimated outflows of relative plasmas that act as accelerators for cosmic ray particles with the highest known energies. The study of such phenomena is considered the main focus of the astrophysical part of our RD. The work of Mr. Middelberg is therefore complementary to the work at LS TP4, where the theoretical description of the corresponding phenomena is in the foreground.
Applications of VLBI technology at the RUB are new and must be publicized accordingly so that the Ruhr-Universität Bochum is also perceived as a new location in the community. Since there is no other site in Germany outside of Bonn with users of VLBI, a RUB presence here is very significant.
In order to strengthen the international visibility of Dr. Middelberg accordingly, he attended the 10th European VLBI Network Symposium and the EVN Users Meeting "VLBI and the new generation of radio arrays" from September 20 to 24, 2010 with the support of the Research Department "Plasmas with Complex Interactions".

Dr. Marian Lazar at COSPAR 2010
The Scientific Assembly of the Committee on Space Research (COSPAR) is the biggest interdisciplinary conference on space science worldwide, and this year it took place in Bremen (July 18-25, 2010). A large number of technical exhibitions from space industry and research have also been associated to the scientific program.
The Research Department enabled the participation of Dr. Marian Lazar to this special event. He presented new kinetic models for the plasma waves and instabilities based on the existence of suprathermal populations in the solar environments: the corona, the solar wind and the Earth’s magnetosphere. Waves and instabilities play an important role in the acceleration and general transport processes of electrons and ions in interplanetary space. Modeling deviations from Maxwellian equilibrium with suprathermal distributions of Kappatype provides better predictions and fits to the observations. This was a great opportunity to find an increasing interest and support for further analysis of these realistic models, but also to establish new valuable contacts.

Edmund Schüngel at the ESCAMPIG in Novi Sad, Serbia
The cooperation between the group of Prof. Zoltan Donkó at the "Research Institute for Solid State Physics and Optics" in Budapest and the Chair of Plasma and Atomic Physics could be intensified by a research stay in Hungary, which was made possible by the Research Department Plasma.
The joint participation in the ESCAMPIG conference ("Europhysics Conference on the Atomic and Molecular Physics of Ionized Gases") offered the opportunity to collectively present the results obtained in the collaboration between Prof. Donkó's institute and the Chair of Experimental Physics V in Bochum. Through the joint conference contributions of Dr. J. Schulze from Prof. Donkó's group and myself ("The Electrical Asymmetry Effect in geometrically asymmetric discharges", "Charge dynamics in capacitively coupled radio frequency discharges", "Excitation dynamics in electrically asymmetric capacitively coupled radio frequency discharges - experiment, simulation, and model") the results of the RD Plasma cooperation were presented on an international level. The journey from Budapest was very economical, so that the low costs are justified by the necessity and importance of this presentation at an ESCAMPIG (13.07.2010 to 17.07.2010), which is strongly perceived in our field of work.
