To measure the spatial distribution of electric field strength in an atmospheric-pressure helium plasma jet operating in bullet and streamer mode.
Applied optical emission spectroscopy to evaluate an atmospheric-pressure helium plasma jet.
Determined electric field strength profiles using Stark polarization spectroscopy targeting the He I 492.19 nm emission line.
Measured electric field strength remains nearly constant along the axial trajectory of the plasma jet, matching theoretical models of atmospheric helium streamer propagation.
Radial profiling of the axial electric field demonstrates that the observed ring-shaped light emission structure directly results from the spatial field distribution.
