Highly ionized hollow cathode discharge
WebA hollow cathode discharge may be used as a reservoir of sputtered atoms for spectroscopic investigations. The negative glow from the opposite walls of the inner surface of hollow cathode merge to produce a high density of neutral and excited atoms as well as of ions at the center of the hollow cathode. WebA hollow cathode discharge (HCD) is described that produces a highly ionized steady-state plasma (n/sub e/ approximately 10/sup 13/ to 10/sup 14//cm/ sup 3/) at a temperature 1 to …
