Abstract
The hollow cathode is an effective source of dense, low energy plasma. Hollow cathodes
find use in ion beam sources for laboratory and space applications. They can also be used
independently for satellite charge control, and ion beam neutralization. A heaterless hoi
-low cathode design was tested with argon gas used as a propellant. This thesis work inve
-stigated the device properties, that is, the emission currents as a function of discharge
current, propellant flow rate and other physical parameters. Starting behavior was a main
point of the investigation. The results of these experiments were compared with studies of
the conventional hollow cathode.
