09.04.2013 - QUANTITATIVE DETERMINATION OF OH RADICALS BY CAVITY RINGDOWN SPECTROSCOPY IN ATMOSPHERIC PRESSURE MICRO-PLASMAS FOR BIO-MEDICAL APPLICATIONS

From March the 24rd to April 6th, 2013, the PhD-students Simon Schneider and Daniel Schröder from project C1 and A1, as well as Jun.-Prof. Dr. Jan Benedikt, all members of the DFG Research Unit FOR1123, visited the group of Prof. RNDr. Jaroslav Vlcek at the University of West Bohemia, Plzen, CZ.  
During this stay, absolute densities of OH radicals in the effluent of the micro-scaled atmospheric pressure plasma jet (µ-APPJ) have been measured in dependence of different concentrations of water impurities in the feed gas. This has been achieved by using a highly sensitive laser diagnostics called Cavity Ringdown Spectroscopy.
A common publication is in progress and a counter-visit is planned for next year.

28.01.2013 - STEFAN SPIEKERMEIER AT BILKENT UNIVERSITY IN ANKARA

From January 13th till 27th, 2013 Stefan Spiekermeier visited the Group of Prof. Ömer Ilday at Bilkent University, Ankara, Turkey. Dr. Marc Böke, his supervisor, visited as well from January 22nd till 24th, 2013.
His group developed the fiber-laser-system that is used for laser assisted plasma breakdown and phase resolved absorption spectroscopy at RUB. During the stay, a new temperature stabilized oscillator for the laser has been tested. Further improvements for the laser have been discussed. Aside from that, an attempt to ignite a plasma inside a hollow-core-PCF-fiber has been made.

21.01.2013 - DR. ILIJA STEFANOVIĆ AT KHARKIV NATIONAL UNIVERSITY IN UKRAINE

Dr. Ilija Stefanović visited the Kharkiv National University. From January 21st to February the 1st, 2013 Dr. Ilija Stefanović visited Prof. Igor Denysenko from Department of Physics and Technology of Kharkiv National University, Ukraine, and gave the lecture on «Diagnostics and Modeling of RF Plasmas with Nanoparticles». He visited low temperature plasma laboratories and got acquainted with application oriented research on the Department, especially with bipolar ion source. Beside of that, he was invited to Ukrainian National Institute for Physics and Technology, where he gave a lecture with the title «Stability and Similarity Laws of DC Microdischarges». The Ukrainian colleagues presented him their newest results of their different activities, including the basic research on two stelerators and application oriented, low temperature plasma reactors. Dr. Stefanović's travel to Kharkiv has been supported by Alexander von Humboldt-Stiftung in the frame of institutional partnership between Institut für Experimentalphysik II and Department of Physics and Technology, V. N. Karazin Kharkiv National University.
