The purpose of these studies was to examine the axial evolution of the negative glow in a hollow cathode discharge. The time-average negative glow profiles along the central axis of a hollow cathode were recorded for 81 pulse widths over the range of 5-25 µs In Increments of 0.25 at a constant interpulse delay of 206.4 µs. Subsequent numerical processing yielded the instantaneous negative glow profile. The negative glow was viewed through a mesh-covered slot along the length of the hollow cathode. The negative flow profiles were Imaged using a vidicon video camera. A PC-based frame grabber digitized the video Images and stored them for subsequent processing.
