Waveguide-based Microwave Discharge

 

Plasma flow: Under expanded CO_{2} plasma flow
Plasma flow: Under expanded CO2 plasma flow

 

A portable waveguide microwave discharge (WMD) is used for the development of advanced optical diagnostics relevant for the study of aerospace plasma flows. Several configurations of the torch can be realized, which makes it possible to operate with different plasma flow regimes in low pressure environments.
