“…In the present study, the gate width is set as 1000 ns to capture pure copper's plasma spectrum. Of various methods-doppler broadening, ratio method, Saha-Boltzmann plot, and Boltzmann plotfor the determination of plasma temperature (T ), the Boltzmann plot method is widely used for several reasons reported in the literature [20,35,36]. The method enables the calculation of T without knowledge of electron number density and gives a better result as a result of linear curve fitting [20].…”

The paper deciphers the potential of fractal analysis in unveiling the complex plasma dynamics. The light from copper plasma is focused on the slit of a spectrometer, and the spectral variations across the slit are analysed. The plasma temperature (T ) computed from the spectrum at various spatial points of the slit also exhibits a variation similar to that of power spectral fractal dimension (Dp). The study reveals a strong correlation between T and Dp, reflecting the complex dynamics and the compositional anisotropy in plasma. At the plasma core, where the temperature is the highest, and the matter is in the ionised state, the Dp is high, and the lower temperature regions show a lower Dp value. The fractalysis helps analyse plasma temperature without knowing transition probability and the energy of the upperlevel corresponding to each value of wavelength. Thus, the power spectral fractalysis can be considered a surrogate method for understanding the plasma temperature and the particle dynamics involved.

“…The slope of this line is −1/Texct leading to Texct which is a good approximation for Te in the case of LTE. This plot is called Boltzmann plot [38][39][40][41][42][43][44][45]. Each observed Ar atomic line wavelength has an associated energy level ϵi, a statistical weight gi, and atomic transition probability Aij as given in table 1.…”

DC Stabilized Discharges (DCSD) was generated in atmospheric pressure argon for a pin to plate. In this paper, discharge with a flowing argon gas into the air (plasma Source) is investigated by optical emission spectroscopy technique. The emission spectra of excited species of atomic-hydrogen, N2 and Ar were observed and measured. The rotational and vibrational temperatures of the discharge were measured by comparing modelled optical emission spectra with masured spectra from the discharge by using several different vibrational bands of the 2nd positive system (SPS) of N2 ( N2[C 3 Πu] → N2[B 3 Πg]). The optical characteristics of the discharge shown that the DCSD was found to be non-equilibrium with rotational temperature (Tr) of 1087 K and vibrational temperature (Tv) of 1661 K. Boltzmann plot method has been applied to estimate the electronic excitation temperature which was found to be 1.36 eV and 1.1 eV for discharges with argon flow rates of 1.0 SLM & 0.5 SLM respectively. This finding proved the strong non-equilibrium nature of the discharge conditions of the current work.
