The role of Ar III in quantitative spectroscopy on hot argon plasmas
We perform quantitative optical emission spectroscopy on the hot core of the cathode region of a free-burning arc in argon under atmospheric pressure. As the peak temperatures in the centre of the discharge exceed 22 000K we are able to observe three spectra of argon (Ar I, Ar II and Ar III) and the continuum emission. We report on some inconsistencies concerning the evaluation of Ar III radiat...
متن کاملNonequilibrium phenomena and determination of plasma parameters in the hot core of the cathode region in free-burning arc discharges.
We present spectroscopic measurements of plasma parameters (electron density n(e), electron temperature T(e), gas temperature T(g), underpopulation factor b) in the hot-core region in front of the cathode of a low-current, free-burning arc discharge in argon under atmospheric pressure. The discharge is operated in the hot-core mode, creating a hot cathode region with plasma parameters similar t...
متن کاملInvestigation of Cold Atmospheric Pressure Plasma at Radio-frequency 13.56 MHZ
In this study we designed an RF plasma circuit. By using argon as plasma-forming gas, we investigated argon cold plasma plume at atmospheric pressure. Due to the tendency of transferring into arc mode after gas breakdown, resulting from the avalanche of electrons, we employed a glass tube as a dielectric barrier layer to inhibit the occurrence of the arc mode. We used an RF power supply at freq...

متن کاملAbsolute Spatially- and Temporally-Resolved Optical Emission Measurements of rf Glow Discharges in Argon
Spatially- and temporally-resolved measurements of optical emission intensities are presented from rf discharges in argon over a wide range of pressures (6.7 to 133 Pa) and applied rf voltages (75 to 200 V). Results of measurements of emission intensities are presented for both an atomic transition (Ar I, 750.4 nm) and an ionic transition (Ar II, 434.8 nm). The absolute scale of these optical e...
