I'm new to PF, I have an engineering background, but am trying to understand how microwave plasmas are generated. I'm trying to work out if a tuned microwave waveguide can create a plasma in a specific point in the waveguide say over 30 seconds as the microwave energy heats up the waveguide thus causing the plasma to occur? Or does the plasma need a spark or ignition source to start the air ionizing and then the microwave keeps it going/enhances it?
Once the plasma is going, is the spark/ignition source required to keep operating to keep the plasma going, or is the plasma self sustaining?
Just trying to understand.
