Measurement of the DC Stark shift for visible NeI lines and electric field distribution in the cathode sheath of an abnormal glow discharge

Influence of a target on the electric field profile in a kHz atmospheric pressure plasma jet with the full calculation of the Stark shifts

“…Multiple spectroscopic methods based on, for example, line width and line intensity have been developed to obtain these parameters from atomic spectra. [4][5][6][7] Another important parameter is the macroscopic electric field that is formed at the head of the plasma bullet in the plasma jet. The characteristics of the electric field, among which is the space and time evolution of the electric field, commonly determine the energy and flux of the charged particles in the plasma and thus determine the behavior of the discharge.…”

The Study of Ar I and Ne I Spectral Line Shapes in the Cathode Sheath Region of an Abnormal Glow Discharge

“…The corresponding best fit value of E together with the distance d from cathode surface is shown in Figure 7. For more details about the measurement of electric field strength distribution in CS region analyzing the Hα line profiles, see [27]. The analysis of Ne I 511.367 nm line dc Stark shift, previously reported by Jäger and Windholz [14], revealed that the line splits into three Stark components (Figure 3a) but under experimental conditions in [14], only one component is detected.…”

“…The presence of the central peak enabled us to present data in Figure 7 in the function of wavelength shift Δλ instead of wavelength λ. The solid (red) line represent the best fit of experimental data obtained by advanced model function, see Equation 8, given in [27]. The corresponding best fit value of E together with the distance d from cathode surface is shown in Figure 7.…”

Estimation of the maximum electric field strength in the cathode sheath of a Grimm-type glow discharge by end-on view optical emission spectroscopy in neon and argon

“…21,22 Further investigations were extended to the inuence of the Stark effect on the non-hydrogen lines starting with helium, [23][24][25][26] towards heavier elements like neon and argon. [27][28][29][30][31] In a most recent development, [32][33][34] the inuence of the CS electric eld on the complex shapes of Ne II lines is reported as a tool for electric eld mapping.…”
