Discharge Parameters

The results of investigation of low-pressure glow discharge with the hollow cathode for the conditions when the cathode cavity depth is comparable with cavity diameter are presented. Data on current distribution over the hollow-cathode surface using sectioned electrodes are obtained and the length of the cathode sheath is measured. It is shown that for the regime of suppressed glow discharge the main fraction of the total discharge current closes to the nearest to the anode cathode section. For the regime of ordinary glow discharge, when the cavity depth is equal to cavity diameter, discharge current over the cathode surface is distributed uniformly. The estimations of the discharge parameters and the values of the cathode sheath using the model of hollow-cathode discharge sustainment were done. Model agrees well with the experimental data.

Abstract Measurement of Excitation Temperatures in a Glow Discharge Lamp Excitation temperatures indicated from Fe-I and Fe-II spectral lines have been measured in a glow discharge lamp using relative intensities of 49 selected spectral lines. Different excitation temperatures resulted: the temperatures were in the range of 3000 -5000 K (Fe-I lines) and 20000 K (Fe-II lines). The former are hardly, the latter ones strongly affected by discharge parameters. The results are discussed.
