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.
