Determination of Electrons Temperature and Density For Ag, Zn, and Cu metals using Plasma jet System at atmospheric pressure

Abstract

Under atmospheric pressure, an argon plasma stream was sustained and its plasma characteristics were examined. The emission spectra of plasma created in a plasma jet system using argon gas were observed for three metals (Ag, Zn, and Cu) for the anode and varied flow rates ranging from 1–4 L/min. at constant voltage, and normal atmospheric pressure. The spectral lines of excited Ar, Ag, Zn, and Cu species were identified at a wavelength of (650–900) nm .The Debye length, sphere, and temperature of an electron are all measured. Optical emission spectrometer (OES) equipment was used to capture the spectrum produced by the plasma at various argon gas flow rates.The temperature and density of the electron (Te) and (ne) ranges for Ar-gas, Ag, Zn, and Cu-anode increased as the stream pace of argon gas to the plasma made by the release current (D.C.) expanded.(1.241- 1.473)eV and (1.93 x1018–6.38 x1018 ) cm-3 , (1.187– 1.245) eV and (4.32 x1016–6.23 x1016 ) cm-3 , (1.374 -1.631)eV and (4.01 x1018 – 12.1 x1018 ) cm-3 respectively . The intensity of spectral lines, on the other hand, increased.

“…This increase leads to more electrons for the gas, thereby intensifying the ionization process within the water. Figure 1 shows a DC plasma jet device (Aadim & Abbas, 2023;Jihad & Aadim, 2022).…”

Characterization of Magnetized-Plasma System Induced by Laser

“…The average temperature of the electrons, denoted by T e , and the plasma density, denoted by n e , are the two most important parameters that determine the properties of plasma [21][22][23]. The intensity of electronic transition changes obeys the Boltzmann distribution principle according to the plasma temperature (T e ), the transition probability (A ji ) of the detected line, and the statistical weight (g j ) of its upper level, as presented by the formula [24].…”
