week 5: Creating a low temperature plasma
To create a plasma we have to separate some of the electrons from their parent atoms or molecules. This means adding energy. The energy has to be concentrated and applied pretty quickly, before it is lost to the surroundings, and if we want the plasma to keep burning we have to keep up the energy supply.
