18.03.2013 - GAST: PROF. DR. IGOR DENYSENKO
Professor Igor Denysenko of the School of Physics and Technology, V. N. Karazin Kharkiv National University, Ukraine, is a guest of Experimental Physik II from 2nd March to 15th April 2013. We continue our collaboration with Prof. Denysenko in the research field of dusty plasmas. Prof. Denysenko has developed a space-averaged global model to characterize the afterglow of pulsed argon plasmas which contain the large density of hydro-carbonaceous dust particles . This global model is further developed in order to study the time evolution of the dust charge and the rate coefficient for electron collection by dust particles. During Prof. Denysenko’s stay in Bochum, we have prepared an article on this study. Furthermore, an article on a new non-invasive method for measurements of ion fluxes and ion densities in pulsed capacitively-coupled RF plasmas has been submitted. We kindly acknowledge the financial support of the Humbolt Foundation.
