“…According to the trace shown in Fig. 8 and the impossibility to continue OES analysis at higher power values, we can predict an LTE plasma discharge at 360 W, guaranteeing high-quality CNF synthesis with respect to the results obtained at lower power values as established in [16].…”

“…This converter has been tested in different reactor configurations and different plasma morphologies, and its universality has been demonstrated [12], [15]. The special application of this converter is in the synthesis of Carbon Nanofibers (CNFs), where its morphology and chemical analysis are reported in [16]. In this paper, we report the optical and electrical diagnostic during the glowto-arc discharge at helium-methane atmosphere.…”

In this paper, a detailed diagnostic of an ac glowto-arc discharge transition is presented. The behavior of the temporal evolution of voltage and current discharges is studied under an atmosphere of helium-methane. In order to determine the rotational temperature, an optical emissionspectroscopy analysis from glow-to-arc regime discharge is carried out, where the OH and C 2 bands, respectively, which are situated at 306.357 nm (A 2 Σ + , ν = 0 → X 2 Π, ν = 0) and 516.52 nm (d 3 Π g , ν = 0 → a 3 Π u , ν = 0), are used. Several metallic atomic lines were used to calculate the electron temperature. The principal discharge parameters, such as temperature and electron density in the arc regime, are determined. As an application of this glow-arc discharge, the synthesis of carbon nanofibers is reported.Index Terms-Carbon nanofibers (CNFs), glow-arc, highfrequency discharge, swan band, UV-OH band.
