Volker Schulz-von der Gathen

Schulz-von der GathenVolker Schulz-von der Gathen was born in Essen, Germany, on December 25, 1956. He received the PhD degree in Physics from the University of Essen in 1990. Until 2007 he worked at the Institute for Laser- and Plasma Physics at the University of Essen. Then he changed as senior scientist to the Ruhr-University Bochum to the Chair for Experimental Physics II, that is now dedicated to the physics of reactive plasmas. His field of work is the diagnostics of low-temperature plasmas. Apart from electrical diagnostics as Langmuir probes in particular optical diagnostics is in the center of the work group he is actually leading. Optical diagnostics cover passive methods such as optical emission spectroscopy and active laser methods such as e.g. Two-photon absorption laser induced fluorescence spectroscopy to measure absolute densities of a atomic species in the plasma. Since about 10 years his research is centered on atmospheric pressure discharges, so called micro discharges. These are of interest for biological, medical, and environmental applications. Here his group developed an rf excited microplasma jet especially suited for optical diagnostics. The second central device is a so-called microplasma array, that is investigated als in cooperation with the group of R. Dussart from the GREMI at Orleans.
