Popis: |
In a discharge with a hollow cathode the electron energy distribution functions (EEDFs), electron concentration, and absolute intensities of pure helium and helium mixtures with water vapor at pressures of 2-3 mbar were measured. It was shown that under the experiment conditions, the EEDFs were significantly different from the Maxwellian function since the amount of high-energy electrons in the energy range of 7-24 eV was much larger. As the concentration of water molecules in plasma increased, the amount of high-energy electrons decreased. The absolute intensities of a number of helium lines were calculated in coronal model approximation. It was determined that the lines reasonably agreed with the experimental measurements of the absolute intensities. |
