Cylindrical Hollow Cathode

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.

Image Analyses

Experimental study on the effect of cylindrical hollow cathode, working pressure and magnetic field on spatial glow distribution and the characteristics of plasma produced by dc discharge in Argon gas, were investigated by image analyses for the plume within the plasma. It was found that the emission intensity appears as a periodic structure with many peaks appeared between the electrodes. Increasing the pressure leads to increase the number of intensity peaks finally converted to continuous form at high pressure, especially with applied of magnetic field, i.e. the plasma is more stable with the presence of magnetic field. The emission intensity study of plasma showed that the intensity has a maximum value at 1.07 mbar pressure and decrease with more pressure.

Cylindrical Hollow Cathode

Abstract The electric field distribution in the cathode fall and the current-voltage characteristic of a cylindrical hollow cathode are calculated on a purely radial model. The theoretical characteristic is compared with results measured on a H2-and Ar-discharge. From the experimental data, the current density ratio of electrons and ions on the cathode can be calculated. This ratio appears in the correct order of magnitude only if the carrier generation in the cathode fall is taken into account. Comparisons are made with the results of linear theories.
