Abstract The negative glow plasma of a cylindrical hollow cathode dc discharge (0.05 - 1 Torr Argon, 1-30 mA) is investigated as to the position of the glow edge, the axial dependence of the cathode current density, the axial and radial potential distributions, the density and energy of electrons (from Langmuir probe measurements) as dependent on pressure, discharge current and position, etc. It is found that two groups of electrons exist whose energies are < 0.5 eV ~ 3 eV and the ratio of their denisties being 3 up to 20. A phenomenological explanation is given for the relatively high denisty of the fast group, The results are compared with those of other auhors concerning hollow-cathode and linear discharges.

The Difference

Radial distribution of the electric field in the cathode fall region of neon hollow cathode discharge has been derived through the observation of the linear Stark effect of the nd′ ( n = 10–12)-3 p′[½]1 transitions by two-step optogalvanic spectroscopy. The field strength was found to decrease monotonically from the cathode to the negative glow. The depth of the cathode fall region was 0.80 ± 0.05 mm, and the electric field at the cathode surface was 5.2 ± 0.2 kV/cm*—values which compare with the reported values of around 3–4 mm and 3–4 kV/cm in the cathode fall region of Ne glow discharge. The difference and similarity in the values of derived parameters are discussed.
