摘要：
The effect of the inside profile of a hollow cathode on the intensity of plasma plume has been studied in a low-pressure (approximately 3 torr) argon discharge. The effectiveness of three different "inside" profiles of a hollow cathode was compared by performing emission spectroscopy on the plasma plume in each case. A conical-profile hollow cathode produced a plasma plume that was much more intense than the one in a commonly used cylindrical-profile hollow cathode.
