Does anybody suggest me the appropriate method for the estimation of electron temperature and electron density of plasma discharge using optical emission spectroscopy?
Intensity ratio, Stark broadening, Doppler broadening, and Boltzmann plot are the methods to determine electron density and temperature of the cold plasma discharge.
I don't think that the Intensity method is a very good method for estimating electron density and temperature of plasma.
I further have a query; Is the result of the temperature and density obtained by the use of any of these methods same?
I measured electron temperature by using infrared photodiode in Pulsotron-3, as long as said before the watts/m2 depends on plasma temperature (so electron temperature if the thermal stabilized plasma), but it works in high-density plasma, in a low-density plasma a Langmuir probe must be used. You have all needed to build one using formula number 501 at "Fisica" sheet here: Method Useful formula and excel tables for plasma physics V09
I think using Langmuir probes would be efficient.
it is used for example in the Thorello device of low-temperature low density magnetized plasma.
I can show you the method for argon plasma, when you will be in Lodz. We will work together.
