Design and characteristics of the COST Reference Microplasma Jet for bio-medicine — •Judith Golda, Julian Held, and Volker Schulz-von der Gathen — Experimental Physics II, Ruhr-University Bochum, Bochum, Germany

Low temperature atmospheric pressure plasma jet devices enable the production of reactive species while the gas temperature is low. Hence, a variety of different sources is commonly used for surface modification and especially considered for use in bio-medicine. To understand and predict the interaction of plasma with biological tissue, a profound knowledge of the complex system and the underlying processes is crucial.

However, the variety of sources complicates the comparability of results and thus leads to a huge delay in scientific progress. To solve this problem, we developed the COST Reference Microplasma Jet within the European COST Action MP1101 for scientific purposes. Researchers around the world should be able to compare the characteristics of their own sources and their results with this device.

Here, we show the simple and robust design as well as a basic characterization of the COST-Jet. Requirements for reproducible results as well as power, optical emission spectroscopy and gas temperature measurements are presented. Additionally, the heat impact on a treated surface is investigated by Schlieren imaging, thermocouple measurements and comparison to numerical simulations.
