Different elements, same results: time-resolved temperature determination by oxygen and nitrogen elements

Abstract The core purpose of this research is to use optical emission spectroscopy determine the electron temperature ( T e ) a hydrogen plasma generated in capillary discharge plasma, with focus on its temporal variation. density n first determined using Stark broadening technique, which measures spectral lines as result electric field plasma. Subsequently, passive spectroscopic technique employed estimate by detecting emitted light from This detection performed visible range spectrometer. In study, two elements, oxygen and nitrogen, are specifically selected based chemical composition capillary. estimated line ratio method, involves comparing intensities specific elements. By analyzing these ratios, can be inferred. combination method provides valuable insights into plasma's physical characteristics, temperature.
