Formation of stable direct current microhollow cathode discharge by venturi gas flow system for remote plasma source in atmosphere
We introduce a microhollow cathode configuration with venturi gas flow to ambient air in order to obtain glow discharge at atmospheric pressure. Stable microhollow cathode discharge was formed in a 200 μ m diameter at 9 mA and the optimum value of gas velocity × diameter for hollow cathode effect wa...
