In the last two decades a rapid increase in research on nonequilibrium atmospheric-pressure discharges has occurred. Applications covers the fields of material science, plasma assisted combustion, plasma medicine. The different devices used (surface discharge, jets, microdischarge) are strongly influenced by several processes, and show a transient behaviour strongly influenced by collisions.
In the presence of such characteristics, the development and deployment of optical diagnostics is an essential tools for the understanding of microscopic processes and the development of new innovative plasma tools.
In our lab the diagnostics tools available are the following:
