Idea / History

The idea of the COST Reference Microplasma Jet design was to create an inexpensive, simple and robust design. It should be usable in different laboratories and composed of inert materials. It should include internal probes and be electrically safe. Additionally, the design should be openly available for the research community.
The COST Reference Microplasma Jet design is based on the concept of the micro-scaled atmospheric pressure plasma jet developed by Schulz-von der Gathen et al. [see preceeding publications]. The µ-APPJ has already been well characterized during the past 10 years using modeling techniques and experimental approaches.

For the COST Reference Microplasma Jet, the design of the µ-APPJ was further improved and several shortcomings of the original design were addressed.
