Plasma sources

Development and characterization of atmospheric pressure plasmas is a core competence of INP . Various methods and systems are developed depending on the specific application and customer requirements. Precise characterization of the sources and basic knowledge of plasma parameters and processes makes it possible for us to selectively design new processes, or optimize existing technologies.

The objective of our activities is research and development of integrated atmospheric pressure plasma systems as new production tools, or for use in environmental technology and the healthcare sector. For these tasks, the INP has special laboratories in which plasma sources can be designed and created or characterized via plasma diagnostics. Moreover, the activities are supported through an extensive research infrastructure of the entire institute, which in addition to state-of-the-art methods of plasma diagnostics, also offers a microbiological laboratory, a cell culture laboratory, plasma chemical analysis, environmental monitoring systems, and diagnostics for surface properties and material properties.
